04 Java Programming in Urdu- - Variables & Data Types

 Variables and Types

Although Java is object oriented, not all types are objects. It is built on top of basic variable types called primitives.

Here is a list of all primitives in Java:

·         byte (number, 1 byte)

·         short (number, 2 bytes)

·         int (number, 4 bytes)

·         long (number, 8 bytes)

·         float (float number, 4 bytes)

·         double (float number, 8 bytes)

·         char (a character, 2 bytes)

·         boolean (true or false, 1 byte)

Java is a strong typed language, which means variables need to be defined before we use them.
