Please explain me, output of this code?

Question

public class Program {
public static void main(String[] args) {
String s1="java";
String s2="java";
String s3="JAVA";
int i=s1.compareTo(s2);
int j=s2.compareTo(s3);
int k=s3.compareTo(s2);
System.out.println(i);
System.out.println(j);
System.out.println(k);
}
}

//output
/*
o
32
-32
*/

Answer 1

ASCII value of 'j': 106
ASCII value of 'J': 74

first output is 0 because s1 == s2.
second output is positive because s2 > s3.
third output is negative because s3 < s2.

You get 32 because the first different letters in s2 and s3 are 'j' and 'J', and the difference between them is 106-74 = 32.
