Java Character toTitleCase() Method

The toTitleCase(char ch) method of Character class converts the given character argument to the titlercase using a case mapping information which is provided by the Unicode Data file. It should be noted that Character.isTitleCase(Character.TitleCase(ch)) may not always return true for some characters.

It has been seen that if a character has no explicit titlecase mapping and is not a titlecase character as per the Unicode Data file, then an uppercase mapping is returned. On the other hand, if the character argument is already a titlecase character, then the same value will be returned.

Syntax

Parameter

ch: It is the character that needs to be converted.

Return Value

The toTitleCase(char ch) method returns the titlecase of the given character. Otherwise, this method returns the character itself.

Example 1

public class JavaCharacterToTitleCaseExample1 {
    public static void main(String[] args) {
      // Create four char primitives ch1, ch2, ch3 and ch4.
      char ch1, ch2, ch3, ch4;
      // Assign  the values to ch1 and ch2.
      ch1 = 'b';
      ch2 = 'm';
      // Assign the titlecase of ch1 and ch2 to ch3 and ch4 respectively.
      ch3 = Character.toTitleCase(ch1);
      ch4 = Character.toTitleCase(ch2);
      String str1 = "The titlecase of character '" + ch1 + "' is given as: " + ch3;
      String str2 = "The titlecase of character '" + ch2 + "' is given as: " + ch4;
      // Print the values of ch3 and ch4.
      System.out.println( str1 );
      System.out.println( str2 );
   }
}

Test it Now

Output:

The titlecase of character 'b' is given as: B
The titlecase of character 'm' is given as: M

Example 2

public class JavaCharacterToTitleCaseExample2 {
    public static void main(String[] args) {
      // Create four char primitives ch1, ch2, ch3 and ch4.
      char ch1, ch2, ch3, ch4;
      // Assign  the values to ch1 and ch2.
      ch1 = ')';
      ch2 = 'G';
      // Assign the titlecase of ch1 and ch2 to ch3 and ch4 respectively.
      ch3 = Character.toTitleCase(ch1);
      ch4 = Character.toTitleCase(ch2);
      String str1 = "The titlecase of character '" + ch1 + "' is given as: " + ch3;
      String str2 = "The titlecase of character '" + ch2 + "' is given as: " + ch4;
      // Print the values of ch3 and ch4.
      System.out.println( str1 );
      System.out.println( str2 );
   }
}

Output:

The titlecase of character ')' is given as: )
The titlecase of character 'G' is given as: G

Java Character toTitleCase()Method

The toTitleCase(int codePoint) method of Character class converts the given character(Unicode code point) argument to the titlercase using a case mapping information which is provided by the Unicode Data file.

It should be noted that Character.isTitleCase(Character.TitleCase(codePoint)) may not always return true for some characters.

Syntax

Parameter

codePoint: It is the codePoint which is the character that needs to be tested.

Return Value

The toTitleCase(int codePoint) method returns the titlecase of the given character(Unicode code point). Otherwise, this method returns the character itself.

Example 1

public class JavaCharacterToTitleCaseExample_1 { 
   public static void main(String[] args) {
      // Create four int primitives.
      int cp1, cp2, cp3, cp4;
      // Assign the values to cp1 and cp2.
      cp1 = 0x0099; 
      cp2 = 0x0080;
      // Assign the titlecase of cp1 and cp2 to cp3 and cp4 respectively.
      cp3 = Character.toTitleCase(cp1);
      cp4 = Character.toTitleCase(cp2);
      String str1 = "The titlecase for the character '" + cp1 + "' isgiven as: " + cp3;
      String str2 = "The titlecase for the character '" + cp2 + "' isgiven as: " + cp4;
      // Print the values of cp3 and cp4.
      System.out.println( str1 );
      System.out.println( str2 );
   }
}

Test it Now

Output:

The titlecase for the character '153' isgiven as: 153
The titlecase for the character '128' isgiven as: 128

Example 2

public class JavaCharacterToTitleCaseExample_2 { 
   public static void main(String[] args) {
      // Create four int primitives.
      int cp1, cp2, cp3, cp4;
      // Assign the values to cp1 and cp2.
      cp1 = 273; 
      cp2 = 156;
      // Assign the titlecase of cp1 and cp2 to cp3 and cp4 respectively.
      cp3 = Character.toTitleCase(cp1);
      cp4 = Character.toTitleCase(cp2);
      String str1 = "The titlecase for the character '" + cp1 + "' isgiven as: " + cp3;
      String str2 = "The titlecase for the character '" + cp2 + "' isgiven as: " + cp4;
      // Print the values of cp3 and cp4.
      System.out.println( str1 );
      System.out.println( str2 );
   }
}

Output:

The titlecase for the character '273' isgiven as: 272
The titlecase for the character '156' isgiven as: 156
