Literal Formats for Character - Example

This section provides a tutorial example on how to use character literals in different formats: single characters or escape sequences enclosed in single quotes.

Now let's see a tutorial program example on character literals in different formats:

 * Copyright (c) All Rights Reserved.

class CharacterLiteral {
   public static void main(String[] a) { o = System.out;
      o.println("Character Literals:");
      o.println("   ASCII char:     'A'       = "+'A');
      o.println("   Control char:   '\\n'      = "+'\n');
      o.println("   Special char:   '\\\\'      = "+'\\');
      o.println("   Unicode char:   '\\u0041'  = "+'\u0041');
      o.println("   Decimal code:   '\\101'    = "+'\101');

Compile this example program in a command window and run it:

herong> javac

herong> java CharacterLiteral

Character Literals:
   ASCII char:     'A'       = A
   Control char:   '\n'      =

   Special char:   '\\'      = \
   Unicode char:   '\u0041'  = A
   Decimal code:   '\101'    = A

Hope you know how to use character literals properly now.
