Java.lang.Character.isSupplementaryCodePoint() Method



The java.lang.Character.isSupplementaryCodePoint(int codePoint) determines whether the specified character (Unicode code point) is in the supplementary character range.


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

public static boolean isSupplementaryCodePoint(int codePoint)


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

Return Value

This method returns true if the specified code point is between MIN_SUPPLEMENTARY_CODE_POINT and MAX_CODE_POINT inclusive, false otherwise.




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

Live Demo
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 = 0x10ffd;
      cp2 = 0x004ca;

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

       *  check if cp1, cp2 are in supplementary character range
       *  and assign results to b1, b2
      b1 = Character.isSupplementaryCodePoint(cp1);
      b2 = Character.isSupplementaryCodePoint(cp2);

      String str1 = "cp1 represents a supplementary code point is " + b1;
      String str2 = "cp2 represents a supplementary code point 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 supplementary code point is true
cp2 represents a supplementary code point is false
