Java Integer compareUnsigned() method

The compareUnsigned() method of the 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 01 :To show working of java.lang.Integer.compareUnsigned() method. 

java

// 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

Example 02: To show the working of ‘compareUnsigned()’ method. 

Java

import java.io.*; //imports the java.io package,

class GFG {
    public static void main(String[] args)
    {
        int x = -100;
        int y = 200; // initialize them to the values -100
                     // and 200

        int result = Integer.compareUnsigned(x, y);
        if (result < 0) {
            System.out.println(
                "x is less than y"); // print statement
        }
        else if (result > 0) {
            System.out.println("x is greater than y");
        }
        else {
            System.out.println("x is equal to y");
        }
    }
}

Output:

x is greater than y
