Java.lang.Character.getDirectionality() Method

Advertisements


Description

The java.lang.Character.getDirectionality(int codePoint) returns the Unicode directionality property for the given character (Unicode code point). Character directionality is used to calculate the visual ordering of text. The directionality value of undefined character is DIRECTIONALITY_UNDEFINED.

Declaration

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

public static byte getDirectionality(int codePoint)

Parameters

  • codePoint - the character (Unicode code point) for which the directionality property is requested

Return Value

This method returns the directionality property of the character.

Exception

  • NA

Example

The following example shows the usage of lang.Character.getDirectionality() 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 = 0x2323;
      cp2 = 0x2c60;

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

      // assign directionality of cp1, cp2 to b1, b2
      b1 = Character.getDirectionality(cp1);
      b2 = Character.getDirectionality(cp2);

      /**
       *  byte value 13  represents DIRECTIONALITY_OTHER_NEUTRALS
       *  byte value -1  represents DIRECTIONALITY_UNDEFINED
       */
       
      String str1 = "Directionality of cp1 is " + b1;
      String str2 = "Directionality of cp2 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:

Directionality of cp1 is 13 
Directionality of cp2 is -1
