Give the output of the following program:
public class StringCheck {
boolean foo(String str) {
int x = str.compareTo("INCOMMUTABLE");
System.out.println("x=" + x);
boolean ret = x == 0 ? true : false;
return ret;
}
public static void main(String[] args) {
StringCheck obj = new StringCheck();
boolean a = obj.foo("INCOMPUTABLE");
System.out.println(a);
}
}

Answer
x=3
false
Working
Output of "INCOMPUTABLE".compareTo("INCOMMUTABLE") will be:
ASCII of P - ASCII of M
⇒ 80 - 77
⇒ 3
Value of x becomes 3. As x is not equal to 0 so ternary operator assigns false to ret. foo method returns back this false that gets assigned to a in main method and then printed as the output.
