Java Tutorial : Java wrapper class (Character class methods) |
public class WrapperClassTest { public static void main(String[] args) { /* * Determines whether the specified char value is a * letter. */ boolean isLetter = Character.isLetter('a'); System.out.println("Character.isLetter('a') = " + isLetter); /* * Determines whether the specified char value is a * digit. */ boolean isDigit = Character.isDigit('2'); System.out.println("Character.isDigit('2') = " + isDigit); /* * Determines whether the specified char value is * white space. */ boolean isWhiteSpace = Character.isWhitespace(' '); System.out.println("Character.isWhitespace(' ') = " + isWhiteSpace); /* * Determines whether the specified char value is * uppercase. */ boolean isUpperCase = Character.isUpperCase('A'); System.out.println("Character.isUpperCase('A') = " + isUpperCase); /* * * Determines whether the specified char value is * lowercase. */ boolean isLowerCase = Character.isLowerCase('a'); System.out.println("Character.isLowerCase('a') = " + isLowerCase); /* * Returns the uppercase form of the specified char * value. */ System.out.println("Character.toUpperCase('m') = " + Character.toUpperCase('m')); /* * Returns the lowercase form of the specified char * value. */ System.out.println("Character.toLowerCase('B') = " + Character.toLowerCase('B')); /* * Returns a String object representing the * specified character value — that is, a * one-character string. */ String str = Character.toString('u'); System.out.println("Character.toString('u') = " + str); } }Output
Character.isLetter('a') = true Character.isDigit('2') = true Character.isWhitespace(' ') = true Character.isUpperCase('A') = true Character.isLowerCase('a') = true Character.toUpperCase('m') = M Character.toLowerCase('B') = b Character.toString('u') = uRefer:
