primitive types in java

Primitive Types and Values
  • A primitive type is predefined by the Java programming language and named by its reserved keyword
PrimitiveType:NumericType boolean
IntegralType: one ofbyte short int long char
FloatingPointType: one offloat double
  • Primitive values do not share state with other primitive values.
  • A variable whose type is a primitive type always holds a primitive value of that same type.
  • The value of a variable of primitive type can be changed only by assignment operations on that variable and decrement operator.
  • The numeric types are the integral types and the floating-point types.
  • The integral types are byte, short, int, and long, whose values are 8-bit,16-bit, 32-bit and 64-bit signed two’s-complement integers, respectively, andchar, whose values are 16-bit unsigned integers representing UTF-16 code units.
  • The floating-point types are float, whose values include the 32-bit IEEE 754
    floating-point numbers, and double, whose values include the 64-bit IEEE 754
    floating-point numbers.
  • The boolean type has exactly two values: true and false.
