Java.lang.Character.toTitleCase() Method



The java.lang.Character.toTitleCase(int codePoint) converts the character (Unicode code point) 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 character argument is already a titlecase character, the same character value will be returned.

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


Following is the declaration for java.lang.Character.toTitleCase() method

public static int toTitleCase(int codePoint)


codePoint − the character (Unicode code point) to be converted

Return Value

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




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 int primitives
      int cp1, cp2, cp3, cp4;

      // assign values to cp1, cp2
      cp1 = 0x0067; // represents g
      cp2 = 0x005e; // represents ^

      // assign titlecase of cp1, cp2 to cp3, cp4
      cp3 = Character.toTitleCase(cp1);
      cp4 = Character.toTitleCase(cp2);

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

      // print cp3, cp4 values
      System.out.println( str1 );
      System.out.println( str2 );

Let us compile and run the above program, this will produce the following result −

Titlecase equivalent of 103 is 71
Titlecase equivalent of 94 is 94
