Answer with Explanation

(a) Character.toUpperCase ('a')

Output
A
Explanation

In Java, the Character.toUpperCase(char ch) method is used to convert a given character to its uppercase equivalent, if one exists. So, the output is uppercase 'A'.

(b) Character.isLetterOrDigit('#')

Output
false
Explanation

Character.isLetterOrDigit() method returns true if the given character is a letter or digit, else returns false. Since, hash (#) is neither letter nor digit, the method returns false.
