Java Byte compareUnsigned() method

The compareUnsigned() method of Java Byte class compares two byte objects numerically by treating the values as unsigned.

Syntax:

Parameters:

The parameters 'x' and 'y' represent the first and second byte 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 JavaByteCompareUnsignedExample1 {
	public static void main(String[] args) {
		byte b1=-9;
		byte b2=-10;
		int val=Byte.compareUnsigned(b1, b2);
		System.out.println("compareUnsigned method will return "+val);
	}
}

Test it Now

Output:

compareUnsigned method will return 1

Example 2

public class JavaByteCompareUnsignedExample2 {
	public static void main(String[] args) {
		byte b1=-9;
		byte b2=-10;
		int val=Byte.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);
		}
	}
}
