Java Integer compareUnsigned() method
  • Last Updated : 05 Dec, 2018

The compareUnsigned() method of Integer class of java.lang package compares two integer values (x, y) given as a parameter, treating the values as unsigned and returns the value zero if (x==y), if (x < y) then it returns a value less than zero and if (x > y) then it returns a value greater than zero.

Syntax :

public static int compareUnsigned(int x, int y)
Parameter :
x : the first int to compare
y : the second int to compare
Return :
This method returns the value zero if (x==y), 
if (x < y) then it returns a value less than zero 
and if (x > y) then it returns a value greater than zero,
treating the values(x, y) as unsigned.

Example :To show working of java.lang.Integer.compareUnsigned() method.




// Java program to demonstrate working
// of java.lang.Integer.compareUnsigned() method
import java.lang.Integer;
  
class Gfg {
  
    // driver code
    public static void main(String args[])
    {
        int a = 100;
        int b = 200;
  
        // as 100 less than 200, Output will be a value less than zero
        System.out.println(Integer.compareUnsigned(a, b));
  
        int x = 28;
        int y = 28;
  
        // as 28 equals 28, Output will be zero
        System.out.println(Integer.compareUnsigned(x, y));
  
        int w = 15;
        int z = 8;
  
        // as 15 is greater than 8, Output will be a value greater than zero
        System.out.println(Integer.compareUnsigned(w, z));
  
        int m = 15;
        int n = -8;
  
        // as 15 is greater than -8,
        // but -8 will be treated as an unsigned number
        // which will be greater than 15
        // Output will be a value less than zero
        System.out.println(Integer.compareUnsigned(m, n));
    }
}


Output:

-1
0
1
-1
