// method of Character.UnicodeBlock class
public class Of {
public static void main(String args[]) {
// By using of(Char ch) method is to return the UnicodeBlock name
// containing the given char value
Character.UnicodeBlock ub1 = Character.UnicodeBlock.of('+');
Character.UnicodeBlock ub2 = Character.UnicodeBlock.of('u');
Character.UnicodeBlock ub3 = Character.UnicodeBlock.of('/');
Character.UnicodeBlock ub4 = Character.UnicodeBlock.of('a');
Character.UnicodeBlock ub5 = Character.UnicodeBlock.of('A');
// Display UnicodeBlock name
System.out.println("ub1 = " + ub1);
System.out.println("ub2 = " + ub2);
System.out.println("ub3 = " + ub3);
System.out.println("ub4 = " + ub4);
