Question

Write the output of the following.

boolean b1 = Character.isDigit('h');

System.out.println(b1);

Answer 1

false

Explanation:

The method Character.isDigit('h') checks whether the character inside the parentheses is a numeric digit (0–9). Because it 'h' is a lowercase letter and not a number, the method evaluates to it, which is then stored in b1 and printed.
