what is the range of int in java
An int is a high performance, streamlined beast for calculating numbers in the range -2,147,483,648 [-2 31] aka Integer.MIN_VALUE to +2,147,483,647 [2 31-1] aka Integer.MAX_VALUE. An int is a bare bones 32-bit chunk of information. int variables are mutable. Unless you mark them final, you can change their value at any time.
