💻 Program Code


public class CompareToMethodExample {

public static void main(String args[]){
	String s1="hello";
	String s2="hello";
	String s3="meklo";
	String s4="hemlo";
	String s5="flag";
	System.out.println(s1.compareTo(s2));//0 because both are equal
	System.out.println(s1.compareTo(s3));//-5 because "h" is 5 times lower than "m"
	System.out.println(s1.compareTo(s4));//-1 because "l" is 1 times lower than "m"
	System.out.println(s1.compareTo(s5));//2 because "h" is 2 times greater than "f"
   }
