Byte Class Fields in Java with example
  • Last Updated : 12 Oct, 2018

Byte class is a wrapper class for the primitive type byte which contains several methods to effectively deal with a byte value like converting it to a string representation, and vice-versa. An object of Byte class can hold a single byte value.

Byte class offers four constants in the form of Fields. These are:

  • MAX_VALUE:The MAX_VALUE is a instance variable of Byte class which is used to return the maximum byte value.

    Syntax:

    public static final byte MAX_VALUE

    Usage:



    Byte.MAX_VALUE

    Return Value: It returns a byte value equal to 127.

    Below is the implementation of MAX_VALUE:




    // Java code to implement
    // MAX_VALUE of Byte class
      
    class GFG {
        public static void main(String[] args)
        {
      
            // byte variable
            byte max_value;
      
            // MAX_VALUE Byte class
            max_value = Byte.MAX_VALUE;
      
            // printing the MAX_VALUE
            System.out.println(max_value);
        }
    }
    Output:
    127
    
  • MIN_VALUE:The MIN_VALUE is a instance variable of Byte class which is used to return the minimum byte value.

    Syntax:

    public static final byte MIN_VALUE

    Usage:

    Byte.MIN_VALUE

    Return Value: It returns a byte value equal to -128.

    Below is the implementation of MIN_VALUE:




    // Java code to implement
    // MIN_VALUE of Byte class
      
    class GFG {
        public static void main(String[] args)
        {
      
            // byte variable
            byte min_value;
      
            // MIN_VALUE Byte class
            min_value = Byte.MIN_VALUE;
      
            // printing the MIN_VALUE
            System.out.println(min_value);
        }
    }
    Output:



    -128
    
  • SIZE:The SIZE is a instance variable of Byte class which is used to return number of bits required to represent a byte value in binary representation (two’s complement).

    Syntax:

    public static final int SIZE

    Usage:

    Byte.SIZE

    Return Value: It returns a int value equal to 8.

    Below is the implementation of SIZE:




    // Java code to implement
    // SIZE of Byte class
      
    class GFG {
        public static void main(String[] args)
        {
      
            // SIZE Byte class
            int output = Byte.SIZE;
      
            // printing the output
            System.out.println(output);
        }
    }
    Output:
    8
    
  • TYPE: The TYPE is a instance variable of Byte class which is used to return Class instance representing the primitive data type byte.

    Syntax:

    public static final Class<Byte> TYPE

    Usage:

    Byte.TYPE

    Return Value: It returns an Class instance representing the primitive data type byte.

    Below is the implementation of TYPE:




    // Java code to implement
    // TYPE of Byte class
      
    class GFG {
        public static void main(String[] args)
        {
      
            // TYPE variable of Byte class
            Class<Byte> output = Byte.TYPE;
      
            // printing the output
            System.out.println(output);
        }
    }
    Output:
    byte
