public class IsWhitespaceOfCharacterClass {
    public static void main(String[] args) {
        // It returns true because the passing character is space

        // It returns false because the passing character is not whitespace   
        boolean result3 = Character.isWhitespace('6');

        // Display values of result1 , result2 and result3
        System.out.println("Character.isWhitespace(' '): " + result1);
        System.out.println("Character.isWhitespace('\n'): " + result2);
        System.out.println("Character.isWhitespace('6'): " + result3);
