Usage

From source file:Main.java

public static void main(String[] args) throws Exception {

    int i = 64;/*  ww w  .j a v a  2 s. co m*/
    String aChar = new Character((char) i).toString();
}

From source file:Main.java

public static void main(String[] args) {
    // Using the constructor
    Character c1 = new Character('A');

    // Using the factory method - preferred
    Character c2 = Character.valueOf('2');
    Character c3 = Character.valueOf('-');

    // Getting the wrapped char values
    char cc1 = c1.charValue();
    char cc2 = c2.charValue();
    char cc3 = c3.charValue();

    System.out.println("c1 = " + c1);
    System.out.println("c2 = " + c2);
    System.out.println("c3 = " + c3);

    // Using some Character class methods on c1
    System.out.println("isLowerCase c1    = " + Character.isLowerCase(cc1));
    System.out.println("isDigit c1    = " + Character.isDigit(cc1));
    System.out.println("isLetter c1    = " + Character.isLetter(cc1));
    System.out.println("Lowercase of  c1    = " + Character.toLowerCase(cc1));

    // Using some Character class methods on c2
    System.out.println("isLowerCase c2    = " + Character.isLowerCase(cc2));
    System.out.println("isDigit c2    = " + Character.isDigit(cc2));
    System.out.println("isLetter c2    = " + Character.isLetter(cc2));
