Usage

From source file:Main.java

public static void main(String[] argv) {
    System.out.println(Character.toLowerCase('T'));

}

From source file:Main.java

public static void main(String[] args) {
    int cp1 = 0x0050;
    int cp2 = 0x2100;

    int cp3 = Character.toLowerCase(cp1);
    int cp4 = Character.toLowerCase(cp2);

    String str1 = "Lowercase equivalent of cp1 is " + cp3;
    String str2 = "Lowercase equivalent of cp2 is " + cp4;

    System.out.println(str1);//ww w .ja  v a  2 s.  c  om
    System.out.println(str2);
}
