In Java, the substring(int beginIndex, int endIndex) method returns a new string starting from beginIndex (inclusive) and ending at endIndex (exclusive).
Example:
String str = “example”;
System.out.println(str.substring(0, 0));
Output: “”
This means an empty string is returned.
Explanation:
beginIndex = 0 (inclusive)
endIndex = 0 (exclusive)
No characters are selected, so the result is an empty string “”.

Key Difference
Term Whitespace Unicode Space Character
Definition Any character that creates “blank” space in text (invisible characters that separate words or lines). Specific space-like characters defined in the Unicode standard.
Scope A broad category that includes a variety of invisible characters like spaces, tabs, and newlines. A subset of Unicode characters that are defined as various types of space.
Examples ‘ ‘ (space), \n (newline), \t (tab), \r (carriage return) U+0020 (Space), U+00A0 (No-Break Space), U+2003 (Em Space), U+2009 (Thin Space), etc.
In Java / Programming Identified by Character.isWhitespace() Each Unicode space has a specific code point, width, and behavior in rendering.
1. Whitespace Characters
These are general characters that create space but are often interpreted by programming languages or parsers.
In Java, Character.isWhitespace(c) returns true for:
Standard space ‘ ‘ (U+0020)
Tab \t (U+0009)
Newline \n (U+000A)
Carriage return \r (U+000D)
Vertical tab \u000B
Form feed \u000C
All Unicode characters categorized as whitespace.
2. Unicode Space Characters
Unicode defines many space characters explicitly, each with a specific purpose or width. Here are a few notable ones:
Unicode Name Width/Use
U+0020 Space Standard space character
U+00A0 No-Break Space Same as space but prevents line breaks
U+2000 En Quad Space equal to 1 en
U+2001 Em Quad Space equal to 1 em
U+2002 En Space Narrower than em space
U+2003 Em Space Wider space for typesetting
U+2009 Thin Space Very narrow space
U+202F Narrow No-Break Space Narrower than no-break space
U+3000 Ideographic Space Used in East Asian scripts, full-width
These characters may not be detected by simple string manipulations unless Unicode-aware methods are used.
Important Distinctions
All Unicode space characters are whitespace, but not all whitespace characters are Unicode space characters.
Some whitespace characters (like \n, \t) are control characters, not printable spaces.
Unicode spaces may have width, non-breaking behavior, or typographic purpose.
Summary
Concept Includes
Whitespace Spaces, tabs, newlines, form feeds, etc.

Primary amebic meningoencephalitis (PAM) is a rare, usually fatal brain infection caused by the amoeba Naegleria fowleri. This free-living amoeba is commonly found in warm freshwater environments like lakes, rivers, and hot springs, as well as in poorly maintained pools or contaminated water supplies.
PAM occurs when the amoeba enters the body through the nose, typically during activities like swimming or diving. From there, it travels to the brain, causing severe inflammation of the brain and its surrounding membranes (meningoencephalitis). Symptoms usually start within 1–9 days and include headache, fever, nausea, vomiting, stiff neck, confusion, seizures, and coma. The infection progresses rapidly, often leading to death within days if untreated.
Diagnosis is challenging and typically involves detecting the amoeba in cerebrospinal fluid or brain tissue, often confirmed posthumously. Treatment is difficult due to the rapid progression and limited effective drugs, but regimens may include antifungal and antimicrobial agents like amphotericin B, miltefosine, and others, with supportive care. Survival is rare, with only a few documented cases globally.
Prevention focuses on avoiding exposure: using nose clips while swimming in warm freshwater, ensuring proper pool maintenance, and avoiding untreated water for nasal irrigation. The CDC and WHO emphasize that PAM is not contagious and cannot be contracted from drinking contaminated water.

The capital of the Chola Empire during its peak was Gangaikonda Cholapuram , but since there is no such option so “Thanjavur” is the best choice.
Here’s a detailed breakdown:
1. Original Capital: Thanjavur (Tanjore)
Thanjavur was the initial and historic capital of the Chola Empire, especially under kings like Rajaraja Chola I (985–1014 CE).
It was here that the iconic Brihadeeswarar Temple was built — a UNESCO World Heritage Site and a symbol of Chola architectural and political grandeur.
2. New Capital: Gangaikonda Cholapuram
In the reign of Rajendra Chola I (1014–1044 CE), the empire expanded vastly — reaching up to the Ganges River in the north and Southeast Asia (Srivijaya) by naval conquest.
To commemorate this northern expedition and Ganges conquest, he built a new capital called:
Significance:
Served as the imperial capital during the height of Chola power.
Featured a grand temple, the Gangaikondacholeeswarar Temple, modeled on the Brihadeeswarar Temple but with refined architectural innovations.
It symbolized political dominance, cultural sophistication, and religious patronage.
Summary Table:
Final Note:
While Thanjavur laid the foundations of Chola grandeur, Gangaikonda Cholapuram represented the zenith of their political, military, and cultural power.

The Tao Te Ching, attributed to Laozi (Lao Tzu) and composed around the 6th century BCE, is not just a foundational text of Taoism — it is its philosophical heartbeat. Its 81 short chapters, written in poetic verse, provide a cryptic yet profound vision of how to live in harmony with the Tao, or “The Way.”
Below is a deep and structured exploration of how the Tao Te Ching shapes Taoism — culturally, spiritually, ethically, and philosophically.
1. Defines the Concept of Tao (The Way)
The Tao Te Ching is the first and most influential source that attempts to articulate what the Tao is:
This sets the tone for Taoism’s central idea:
The Tao is an unseen, unnameable force that underlies all existence.
It is not a god or a doctrine, but a natural flow — the way things are.
In Taoist practice, this inspires:
Non-interference (wu wei)
Simplicity and naturalness (ziran)
Respect for cycles, change, and paradox
The Tao Te Ching becomes a lens through which reality is interpreted — not controlled.
2. Establishes Wu Wei (Non-action) as a Core Virtue
One of the most revolutionary teachings of the Tao Te Ching is wu wei, often misunderstood as laziness or passivity.
Wu wei means:
Acting in alignment with the Tao — effortlessly and spontaneously.
Avoiding forced actions that go against nature.
Trusting the rhythm of life rather than imposing will upon it.
In Taoist lifestyle, this becomes:
Letting go of overthinking.
Allowing relationships, creativity, and decisions to unfold organically.
3. Provides a Model for the Taoist Sage
The Tao Te Ching doesn’t just speak of abstract ideals — it presents a model human being: the sage or Zhenren (the “true person”).
Qualities of the sage:
Detached from ego, fame, and competition.
Guided by inner clarity and humility.
Leads not by force, but by quiet example.
Taoism embraces this sage archetype, not as a saint, but as a fully natural human — integrated, grounded, and free from duality.
4. Influences Taoist Ethics and Governance
Laozi writes extensively about rulers and governance — using the Tao to guide statecraft.
This reflects a Taoist ethic of minimalism, decentralization, and moral restraint:
Don’t over-regulate.
Don’t impose rigid systems.
Lead by being, not by controlling.
This teaching profoundly shaped early Taoist political thought — as a counterpoint to Confucianism’s structured social order.
5. Shaped Taoist Cosmology and Religion
Although the Tao Te Ching is philosophical, it laid the groundwork for religious Taoism, which emerged centuries later.
Influences include:
The idea of Tao as the source of heaven and earth.
The reverence for balance (yin-yang) and emptiness (wu).
The concept of the immortal or perfected person (xian).
Religious Taoism integrated these with rituals, deities, and practices — but always kept the Tao at its metaphysical core.
6. Promotes Paradox as Spiritual Insight
The Tao Te Ching is rich in paradox:
“Soft overcomes hard.”
“The way forward is back.”
“To know that you do not know is the best.”
This nonlinear, poetic style teaches Taoists to:
See beyond dualistic thinking.
Embrace the unknowable.
Accept contradictions as part of truth.
Taoism thus evolves as a tradition that prizes intuition over logic and emptiness over certainty.
7. Permeates Art, Nature, and Daily Life in Taoism
Because of the Tao Te Ching’s emphasis on:
Flow
Nature
Stillness
Uncarved simplicity (pu)
It influences not just theology, but aesthetics and daily living:
Taoist art emphasizes spontaneity and nature.
Taoist medicine values balance and internal energy.
Taoist diet, exercise (e.g., qigong), and rituals reflect effortless living.
Conclusion: A Book That Is the Tao
The Tao Te Ching doesn’t just describe Taoism — it is Taoism.
Every major principle of Taoism can be traced back to its verses:
Tao as the Source
Wu Wei as practice
Simplicity as wisdom
Paradox as truth
Emptiness as fullness
Its timeless brevity and mystical tone allow it to remain relevant — not just as ancient scripture, but as a living guidebook for balance, freedom, and peace.

1. Zazen: The Heart of Zen Practice
In Zen Buddhism, zazen (seated meditation) is not merely a technique — it is the practice. The word “Zen” itself comes from the Sanskrit dhyāna, which means meditation.
Zazen is not a means to an end. It is the end.
Key Features of Zazen:
Practiced with eyes open, facing a wall or natural space.
Focuses on posture, breath, and presence.
Letting thoughts arise and pass without attachment.
No mantra, visualization, or goal.
This style reflects the Zen ideal: radical simplicity, direct experience, and being fully present.
2. Experiencing ‘Satori’ (Awakening) Through Meditation
Zen does not teach enlightenment through study or belief. Instead, it emphasizes sudden insight (satori) — a flash of understanding or awakening — often cultivated during deep meditation.
Satori is not mystical escapism; it’s a direct perception of reality without filters.
Zazen creates the stillness and awareness necessary for such moments to occur.
As Zen Master Dōgen said:
This forgetting of the self often happens in the stillness of zazen.
3. Beyond the Self: Letting Go of Ego
Zazen reveals the illusion of a fixed, separate self — the very source of suffering in Buddhist thought. Through quiet sitting:
The ego’s chatter quiets.
One witnesses impermanence and interconnectedness.
The mind stops grasping, labeling, and resisting.
This leads to non-dual awareness — a key theme in Zen — where distinctions between self and other dissolve.
4. Living Zen: Meditation Off the Cushion
In Zen, meditation isn’t confined to the cushion. It extends to every act — walking, eating, cleaning, speaking.
This reflects the idea of “everyday mind is the Way.”
When washing dishes, just wash dishes.
When walking, just walk.
This is meditation in action — a seamless life of mindfulness.
Thus, meditation trains the mind to be fully present in the ordinary, turning the mundane into the sacred.
5. Silence Over Scriptures
Zen is known for its “direct transmission outside the scriptures.”
While traditional Buddhism reveres texts, Zen favors experiential wisdom.
Zazen becomes a silent teacher — one that leads to self-realization beyond words.
As a famous Zen saying goes:
Meditation is the act of dropping those opinions — layer by layer.
6. Discipline and Structure: The Role of the Sangha
Meditation in Zen is also practiced in structured environments, like sesshin (intensive retreats) and daily zazen in Zen monasteries.
These sessions emphasize:
Routine and discipline
Group energy (sangha)
Ritual simplicity
Even in strict form, Zen meditation remains profoundly personal.
Conclusion: Why Meditation is the Soul of Zen
Zen meditation is not about achieving something. It’s about being with what is. It’s the practice of:
Observing reality directly,
Letting go of concepts,
Experiencing truth without filters.
It’s not about escaping life — but waking up to life in its raw, unfiltered form.
In Zen, meditation is the gate. But it is also the path, and ultimately, it becomes the destination itself.
