Byte Class Fields in Java with example

Last Updated : 11 Jul, 2025
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 
    // 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 
    // 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 
    // 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 
    // 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
