What You’ll Learn

S2 Labs

Integer datatypes are those whose variables can store negative and positive values.

Types of Integer Datatype

There are 2 integer types that we can use to store values.

  1. Integer (4 bytes) →  Range(-2147483647 to +2147483647)
  2. Long (8 bytes) → Range (-263 to +263-1)

Syntax of Integer Datatype

Integer intValue = 343;

  • If the literal goes out of the integer range then append l or L at the end of the literal because by-default a number is treated as an integer.

Long largeValue = 3434343434L;

  • If the value is not in the range of type defined then the compiles time error is generated.
