Introduction to Java

Java

• Java is a popular programming language.
• Java is used to develop mobile apps, web apps, desktop apps, games and much more.

Features of Java:

Platform Independence

Simple and Familiar

Multithreading

High Performance

Portable

Object Oriented

Robust and Secure

Dynamic

Distributed

Platform Independence:

Java is bytecode can be executed on any platform with the appropriate JVM.

Object Oriented:

Java follows the object-oriented programming paredigm, encapsulation, ingeritance,and polymarphism.

Simple:

Java is syntax is inspired by C++ and C ,making it familiar to may programmers.

Robust and Secure:

Java has feature like memory management, strong type checking, and
exception handling to ensure robust and secure programs.

Multithreading:

Java supports multithreading, allowing multiple tasks to be executed concurrently.

Dynamic:

Java supports dynamic memory allocation and garbage collection, simplifying memory management.

High Performance:

While java programs might not be as fast as compiled languages like C++, javas performance has improved over time,thanks to JVM optimizations.

Distributed:

Java "write once,run anywhere"capability makes it highly portable.

Architecture of Java:

Compiler: Compiler can convert java code to byte code (.java file to .class file) with help of Java development kit(JDK). It translate entire code of the program.

Interpreter: In Java, an interpreter is a program that executes Java bytecode instructions line by line. It's a key component of the Java Virtual Machine (JVM).
