Compare Signed and Unsigned Numbers

Write a Java program to compare two signed and unsigned numbers.

Sample Solution:

Java Code:

public class Main {
    public static void main(String[] args) {
        int in1 = Integer.MIN_VALUE;
		int in2 = Integer.MAX_VALUE;
		System.out.println("Signed integers: " + in1 + ", " + in2);
		System.out.println("-----------------------------------------");
		int compare_Signed_num = Integer.compare(in1, in2);
		System.out.println("Result of comparing signed numbers: " + compare_Signed_num);
		int compare_Unsigned_num = Integer.compareUnsigned(in1, in2);
        System.out.println("Result of comparing unsigned numbers: " + compare_Unsigned_num);
    }
}

Sample Output:

Signed integers: -2147483648, 2147483647
-----------------------------------------
Result of comparing signed numbers: -1
Result of comparing unsigned numbers: 1
