Java.lang.Character.isTitleCase() Method

---

---

Description

The java.lang.Character.isTitleCase(int codePoint) determines if the specified character (Unicode code point) is a titlecase character.

A character is a titlecase character if its general category type, provided by getType(codePoint), is TITLECASE_LETTER.

Some characters look like pairs of Latin letters. For example, there is an uppercase letter that looks like "LJ" and has a corresponding lowercase letter that looks like "lj". A third form, which looks like "Lj", is the appropriate form to use when rendering a word in lowercase with initial capitals, as for a book title.

These are some of the Unicode characters for which this method returns true −

• LATIN CAPITAL LETTER D WITH SMALL LETTER Z WITH CARON
• LATIN CAPITAL LETTER L WITH SMALL LETTER J
• LATIN CAPITAL LETTER N WITH SMALL LETTER J
• LATIN CAPITAL LETTER D WITH SMALL LETTER Z

Many other Unicode characters are titlecase too.

Declaration

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

public static boolean isTitleCase(int codePoint)

Parameters

codePoint − the character (Unicode code point) to be tested.

Return Value

This method returns true if the character is titlecase, false otherwise.

Exception

NA

Example

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

package com.tutorialspoint;

import java.lang.*;

public class CharacterDemo {

   public static void main(String[] args) {

      // create 2 int primitives cp1, cp2
      int cp1, cp2;

      // assign values to cp1, cp2
      cp1 = 0x01c8;
      cp2 = 0x1f09;

      // create 2 boolean primitives b1, b2
      boolean b1, b2;

      /**
       *  check if cp1, cp2 represent titlecase characters
       *  and assign results to b1, b2
       */
      b1 = Character.isTitleCase(cp1);
      b2 = Character.isTitleCase(cp2);

      String str1 = "cp1 represents a titlecase character is " + b1;
      String str2 = "cp2 represents a titlecase character is " + b2;

      // print b1, b2 values
      System.out.println( str1 );
      System.out.println( str2 );
   }
}

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

cp1 represents a titlecase character is true
cp2 represents a titlecase character is false
