• JavaScript programming
• C++ programming
• Python programming

are the basic building blocks of Java programs. They store simple values directly in memory.

• Object data types
• Reference types
• Primitive data types
• Complex data structures

store references (addresses) to objects instead of directly holding values.

• Non Primitive data types

• Static memory allocation
• Direct values
• References to objects

• Used to describe the code for better readability. • Does not affect program execution

• Variable
• Documentation Section (Comments)

• Function
• Loop

Specifies the package in which the class belongs.

• Helps in organizing code.

• Package Declaration

• Namespace
• Library
• Module

Used to import built-in or user-defined classes. • Allows access to predefined Java libraries

• package statement
• import statement
• class declaration
• method definition

• Every Java program must have at least one class. • The class name should match the file name.

• Every Java program can have multiple classes with different names.
• The class name can be anything regardless of the file name.
• Java programs do not require a class to run.
• Class Declaration

The entry point of a Java program. • The program execution starts from here.

• static void main(String args)
• Main Method

• public void start(String[] args)
• void main(String[] args)

Stores data in a program. • Uses different data types (int, double, String, etc.).

• Constants
