Java.lang.Character.toCodePoint() Method

Description

The java.lang.Character.toCodePoint(char high, char low) converts the specified surrogate pair to its supplementary code point value. This method does not validate the specified surrogate pair. The caller must validate it using isSurrogatePair if necessary.

Declaration

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

public static int toCodePoint(char high, char low)

Parameters

• high - the high-surrogate code unit

• low - the low-surrogate code unit

Return Value

This method returns the supplementary code point composed from the specified surrogate pair.

Exception

• NA

Example

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

package com.tutorialspoint;

import java.lang.*;

public class CharacterDemo {

   public static void main(String[] args) {

      // create 2 char primitives ch1, ch2
      char ch1, ch2;

      // assign values to ch1, ch2
      ch1 = '\ud800';
      ch2 = '\udc00';

      // create an int primitive cp
      int cp;

      // assign code point value of surrogate pair ch1, ch2 to cp
      cp = Character.toCodePoint(ch1, ch2);

      String str = "Supplementary code point value is " + cp;

      // print cp value
      System.out.println( str );
   }
}

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

Supplementary code point value is 65536
