Java.lang.Character.toTitleCase() Method

Advertisements


Description

The java.lang.Character.toTitleCase(char ch) converts the character argument to titlecase using case mapping information from the UnicodeData file.

If a character has no explicit titlecase mapping and is not itself a titlecase char according to UnicodeData, then the uppercase mapping is returned as an equivalent titlecase mapping. If the char argument is already a titlecase char, the same char value will be returned.

Note that Character.isTitleCase(Character.toTitleCase(ch)) does not always return true for some ranges of characters.

public static char toTitleCase(char ch)

Parameters

  • ch - the character to be converted

Return Value

This method returns the titlecase equivalent of the character, if any; otherwise, the character itself.

Example

The following example shows the usage of lang.Character.toTitleCase() method.

package com.tutorialspoint;

import java.lang.*;

public class CharacterDemo {

   public static void main(String[] args) {

      // create 4 char primitives
      char ch1, ch2, ch3, ch4;

      // assign values to ch1, ch2
      ch1 = 'p';
      ch2 = '+';

      // assign titlecase of ch1, ch2 to ch3, ch4
      ch3 = Character.toTitleCase(ch1);
      ch4 = Character.toTitleCase(ch2);

      String str1 = "Titlecase of " + ch1 + " is " + ch3;
      String str2 = "Titlecase of " + ch2 + " is " + ch4;

      // print ch3, ch4 values
      System.out.println( str1 );
      System.out.println( str2 );
   }
}
