From Beginning
Java is a versatile, high-level programming language that has been widely used since its release in the mid-1990s. It’s known for its portability, robustness, and ease of use, making it a popular choice for various types of software development.
Java is an object-oriented programming (OOP) language developed by Sun Microsystems (now part of Oracle Corporation). It is designed to be platformindependent, meaning code written in Java can run on any device that has a Java Virtual Machine (JVM) installed.
To start coding in Java, you'll need:
Java is a powerful and widely used programming language that is suitable for beginners and experienced developers alike. Its platform independence, rich ecosystem, and strong community support make it a great choice for a wide range of applications, from web development to mobile apps. Whether you're starting your programming journey or expanding your skills, learning Java can open many doors in the tech industry.

Java is a high-level, object-oriented programming language developed by Sun Microsystems. It is designed to be platform-independent, meaning code written in Java can run on any device that has the Java Virtual Machine (JVM) installed. This "write once, run anywhere" capability is one of Java's key features.
Platform Independence: Java code can run on any platform that supports the JVM.
A class in Java is a blueprint for creating objects. It defines the properties (attributes) and methods (functions) that the objects created from the class can have. For example:
java Copy code
public class Car
{ String
color; int
year;
void drive() {
System.out.println("The car is driving.");
}
}
is a reference comparison operator that checks if two references point to the same object in memory. equals() is a method defined in the Object class that checks if two objects are logically equal based on their content. It's common to override equals() in user-defined classes to provide meaningful equality checks.
Inheritance is a mechanism in Java that allows one class (subclass) to inherit fields and methods from another class (superclass). This promotes code reusability and establishes a relationship between classes. For example:
java Copy code public
class Animal {
void eat() {
System.out.println("Eating...");
}
}
public class Dog extends Animal {
void bark() {
System.out.println("Barking...");
}
}
An interface in Java is a reference type similar to a class but only contains abstract methods (methods without a body) and constants. Interfaces allow for multiple inheritance and define a contract that implementing classes must follow. For example:
java Copy
code
public interface Animal {
void sound();
}
public class Cat implements Animal {
public void sound() {
System.out.println("Meow");
}
}
Exception handling in Java is a mechanism to handle runtime errors, allowing the program to continue its execution without crashing. It uses try, catch, and finally blocks. For example:
java Copy
code try { int result = 10 / 0; // This will throw
an ArithmeticException
} catch (ArithmeticException e) {
System.out.println("Cannot divide by zero.");
} finally {
System.out.println("This block always executes.");
}
Collections in Java are frameworks that provide data structures and algorithms to store, manipulate, and retrieve groups of objects. The main interfaces in the collections framework include List, Set, and Map, each serving different use cases. For example, ArrayList implements the List interface and allows duplicate elements.
The JVM is an abstract computing machine that enables a computer to run Java programs. It converts Java bytecode (compiled Java code) into machine code that the host operating system can execute. The JVM also provides memory management and garbage collection.
