Give the output of the following Character class methods:
(a) Character.toUpperCase ('a')
(b) Character.isLetterOrDigit('#')
Answer:
(a) Character.toUpperCase ('a')

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('#')

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.
