How does the compareTo method work for Strings? if a word comes after another word in the alphabet then it returns positive or negative?

Question

Let's say i write this:

String a = "Hello";
String b = "Goodbye";
int compare = a.compareToIgnoreCase(b);
System.out.println(compare);

What will the printout be?

Answer 1

It compares character by character for each string.

For example in this case When a = "hello" and b = "Goodbye"

It checks first character of a with first character of b and computes the relative difference, if it's same then it checks the next character, else it computes the difference and returns it.
If string a is greater than string b it returns a positive difference else it returns a negative difference.

Answer 2

in this case the out are be 1, because H comes after of G
