Primitive Data Types in Java

in Java, primitive data types are the most basic types of data. They store simple values (not objects) and are very fast. 1. byte Size: 1 byte (8 bits) Range: -128 to 127 Used to save memory in large arrays Example: byte b = 100; 2. short Size: 2 bytes Range: -32,768 to 32,767 Example: short s = 20000; 3. int Size: 4 bytes Most commonly used Range: -2³¹ to 2³¹-1 Example: int num = 100000; 4. long Size: 8 bytes Used for very large numbers Example: long l = 1000000000
