Usage

From source file:Main.java

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

}

From source file:Main.java

public static void main(String[] args) {
    int cp1 = 0x0071;
    int cp2 = 0x0570;

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

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

    System.out.println(str1);//  ww w.j  ava  2s  .c om
    System.out.println(str2);
}

From source file:Main.java
