Java Character getDirectionality() Method

The getDirectionality(char ch) method of Character class is used to return the property of unicode directionality for the given character. Generally, character directionality calculates the visual ordering of the text. The directionality value of undefined char value is DIRECTIONALITY_UNDEFINED.

Syntax

Parameter

ch: It is the char for which the directionality property is requested.

Return Value

It returns the directionality property of the char value.

Example 1

  public class JavaCharactergetDirectionalityExample1 {
   public static void main(String[] args) {
   // Create two character primitives obj1, obj2
   char obj1, obj2;
   // Assign the values to ch1, ch2
   obj1 = 'Q';
   obj2 = '1';
   // create 2 byte primitives b1, b2
   byte b1, b2;
   // Assign the directionality of obj1 and obj2 to b1 and b2 respectively.
   b1 = Character.getDirectionality(obj1);
   b2 = Character.getDirectionality(obj2);
   System.err.println("The directionality of " + obj1 + " is " + b1);
   System.err.println("The directionality of " + obj2 + " is " + b2);
        }
     }

Test it Now

Output:

The directionality of Q is 0
The directionality of 1 is 3

Example 2

import java.util.Scanner;
public class JavaCharactergetDirectionalityExample2 {	
     public static void main(String[] args) {
	 // Ask the user for the first input.
	   System.out.print("Enter the first input:");
	// Use scanner to get the user input
	   Scanner s1 = new Scanner(System.in);
	// Gets the first user input
	   char[] value1 = s1.nextLine().toCharArray();
	// The Unicode directionality property for the given character
	    for (char ch1 : value1) {
	   byte result1 = Character.getDirectionality(ch1);	
System.out.println("The Unicode directionality property for the character " + ch1+ " is " + result1);		
	}
	// Ask the user for the sercond input.
          System.out.print("Enter the second input:");
	// use scanner to get the user input
          Scanner s2 = new Scanner(System.in);
	// gets the user input
	   char[] value2 = s2.nextLine().toCharArray();
	// The Unicode directionality property for the given character
	   for (char ch2 : value2) {
	   byte result2 = Character.getDirectionality(ch2);
System.out.println("The Unicode directionality property for the character " + ch2+ " is " + result2);		
		}	
       } 
}

Test it Now

Output:

Enter the first input:D
The Unicode directionality property for the character D is 0
Enter the second input:4
The Unicode directionality property for the character 4 is 3

Example 3

public class JavaCharactergetDirectionalityExample3 {
    public static void main(String[] args)
      {
	  // Create two int primitives ch1 and ch2 and assign values to them
	       int char1 = 45, char2 = 61;
	 // Assign the directionality
	       byte obj1 = Character.getDirectionality(char1);
	       byte obj2 = Character.getDirectionality(char2);
	       System.err.println("Directionality of first primitive is " + obj1);
	       System.err.println("Directionality of second primitive is " + obj2);
	    }
    }

Test it Now

Output:

Directionality of first primitive is 4
Directionality of second primitive is 13

Java Character getDirectionality() Method

The getDirectionality(int codePoint) method of Character class is used to return the unicode directionality property for the given character. Generally, character directionality is used to calculate the visual ordering of the text. The directionality value for undefined char value is DIRECTIONALITY_UNDEFINED.

Syntax

Parameter

The above method requires only one parameter:

codePoint: It is the character(Unicode code point) for which the directionality property is requested.

Return Value

The getDirectionality(int codePoint) method returns the directionality property of the character.

Example 1

public class JavaCharactergetDirectionality_Example1 {
     public static void main(String[] args) {
	// Initialize the codePoints.
	    int codepoint1 = 36;
	    int codepoint2 = 2001;
	// Convert the codePoint to its numeric value.
	     byte value1 = Character.getDirectionality(codepoint1);
	     byte value2 = Character.getDirectionality(codepoint2);
       // Print the result.
	    System.out.println("codePoint: " + codepoint1);
           System.out.println("Unicode directionality property for the first codePoint is: "+ value1);
	    System.out.println("codePoint: " + codepoint1);
	    System.out.println("Unicode directionality property for the second codePoint is: " + value2);		
		}
	}

Test it Now

Output:

codePoint: 36
Unicode directionality property for the first codePoint is: 5
codePoint: 36
Unicode directionality property for the second codePoint is: 1

Example 2

public class JavaCharactergetDirectionality_Example2 {
   public static void main(String[] args) {
	// Create two int primitives cp1, cp2
	      int obj1, obj2;
      // Assign the values to obj1, obj2
	      obj1 = 323;
	      obj2 = 60;
     // create two byte primitives b1, b2
	      byte b1, b2;
      // assign directionality of cp1, cp2 to b1, b2
	      b1 = Character.getDirectionality(obj1);
	      b2 = Character.getDirectionality(obj2);	       
	      System.err.println("Directionality for first codePoint is " + b1);
	      System.err.println("Directionality of second codePoint is " + b2); 
	   }
	}

Test it Now

Output:

Directionality for first codePoint is 0
Directionality of second codePoint is 13

Example 3

public class JavaCharactergetDirectionality_Example3 {	
	public static void main(String[] args) {
	// Initialize the codePoints.
	   int codepoint1 = 36;
          int codepoint2 = 2001;
          int codepoint3 = 00;
	// Convert the codePoint to its numeric value.
	   byte value1 = Character.getDirectionality(codepoint1);
	   byte value2 = Character.getDirectionality(codepoint2);
          byte value3 = Character.getDirectionality(codepoint3); 
       // Print the result.
	System.out.println("codePoint: " + codepoint1);      
  System.out.println("Unicode directionality property for the first codePoint is: "+ value1);
      System.out.println("codePoint: " + codepoint2);	 
   System.out.println("Unicode directionality property for the second codePoint is: " + value2);	
      System.out.println("codePoint: " + codepoint3);	
    System.out.println("Unicode directionality property for the second codePoint is: " + value3);		
		     }
     }

Test it Now

Output:

codePoint: 36
Unicode directionality property for the first codePoint is: 5
codePoint: 2001
Unicode directionality property for the second codePoint is: 1
codePoint: 0
Unicode directionality property for the second codePoint is: 9
