Datatypes in java
Data Types In Java There are two data types available in Java: 1.Primitive Data Types 2.Reference/Object Data Types (Non Primitive) Primitive Data Types: There are eight primitive data types supported by Java. Primitive data types are predefined by the language and named by a keyword. The eight primitive data types are explained below: byte: Byte data type is an 8-bit signed two's complement integer. Minimum value is -128 (-2^7) Maximum value is 127 (inclusive)(2^7 -1) Default value is 0 Byte data type is used to save space in large arrays, mainly in place of integers, since a byte is four times smaller than an int. Example: byte a = 100 , byte b = -50 short: Short data type is a 16-bit signed integer. Minimum value is -32,768 (-2^15) Maximum value is 32,767 (inclusive) (2^15 -1) Short data type can also be used to save memory as byte data type. A short is 2 times smaller than an int Default value is 0. Example: short s = 10000, short r = -20000 int : Int data type is a 32-b...
