Java Integer compareUnsigned() method

The compareUnsigned() method of Integer class compares two int objects numerically by treating the values as unsigned.

Syntax

public static int compareUnsigned(int x , int y)

Parameters

The parameters ‘x’ and ‘y’ represent the first and second int value to compare.

Return Value

This method returns an integer value.

• It returns zero, if both the parameters are equal(x==y).
• It returns value greater than zero, if x is greater than y as unsigned values(x>y).
• It returns value less than zero, if x if smaller than y as unsigned values (x<y).

Example 1

public class JavaIntegerCompareUnsignedExample1 {
    public static void main(String[] args) {
        byte b1=-9;
        byte b2=-10;
        int val=Integer.compareUnsigned(b1, b2);
        System.out.println("compareUnsigned method will return "+val);
    }
}

Output

compareUnsigned method will return 1

Example 2

public class JavaIntegerCompareUnsignedExample3 {
    public static void main(String[] args) {
        byte b1=-9;
        byte b2=-10;
        int val=Integer.compareUnsigned(b1, b2);
        if (val==0){
            System.out.println(b1+" and "+b2+" are equal");
        }
        else if (val>0){
            System.out.println(b1+" is greater than "+b2);
        }
        else{
            System.out.println(b2+" is greater than "+b1);
        }
    }
}

Output

-9 is greater than -10
