Byte compare() method in Java with examples

The compare() method of Byte class is a built in method in Java which is used to compare two byte values.

Syntax

Byte.compare(byte a, byte b)

Parameters: It takes two byte value ‘a’ and ‘b’ as input in the parameters which are to be compared.



Return Value: It returns an int value. It returns:

  • 0 if ‘a is equal to ‘b,
  • a positive value ‘a’ is greater than ‘b’,
  • a negative value ‘b’ is greater than ‘a’

Below is the implementation of compare() method in Java:

// Java code to demonstrate
// Byte compare() method
  
class GFG {
    public static void main(String[] args)
    {
  
        // byte value 'a'
        byte a = 20;
  
        // byte value 'b'
        byte b = 20;
  
        // compare method of Byte class
        int output = Byte.compare(a, b);
  
        // printing the output
        System.out.println("Comparing " + a
                           + " and " + b + " : "
                           + output);
    }
}
