Write the output of the following String methods:

The outputs are:

(a) true

(b) -1

Explanation:

Given Strings:

String x = "Galaxy";
String y = "Games";

(a) System.out.println(x.charAt(0) == y.charAt(0));

1. x.charAt(0): Retrieves the character at index 0 of x → 'G'.

2. y.charAt(0): Retrieves the character at index 0 of y → 'G'.

3. Comparison: 'G' == 'G' → true.

(b) System.out.println(x.compareTo(y));

1. x.compareTo(y): Compares x ("Galaxy") with y ("Games") lexicographically (character by character based on Unicode values). The comparison is based on the first differing character:

   • 'G' == 'G' → Equal, move to the next characters.
   • 'a' == 'a' → Equal, move to the next characters.
   • 'l' == 'm' → 'l' (Unicode 108) is less than 'm' (Unicode 109).

2. Result:

   • x.compareTo(y) → 108 - 109 = -1.
