Character.isSupplementaryCodePoint() Method in Java - GeeksforGeeks

Last Updated : 06 Dec, 2018

The

is an inbuilt method in java that determines whether the specified character (Unicode code point) is in the supplementary character range.

public static boolean isSupplementaryCodePoint(int codePoint)

The

of integer type refers to the character (Unicode code point) that is to be tested.

This method returns true if the specified code point is between MIN_SUPPLEMENTARY_CODE_POINT and MAX_CODE_POINT inclusive, false otherwise. Below programs illustrate the Character.isSupplementaryCodePoint() method:

// Code to illustrate the isSupplementaryCodePoint() method
import java.lang.*;

public class gfg {

    public static void main(String[] args)
    {

        // Create 2 int primitives c1, c2 and assign values
        int c1 = 0x10ffd, c2 = 0x154ca;

        boolean bool1 = Character.isSupplementaryCodePoint(c1);
        boolean bool2 = Character.isSupplementaryCodePoint(c2);

        String str1 = "c1 represents a supplementary code point is " + bool1;
        String str2 = "c2 represents a supplementary code point is " + bool2;

        // Displaying the result
        System.out.println(str1);
        System.out.println(str2);
    }
}

c1 represents a supplementary code point is true
c2 represents a supplementary code point is true

// Code to illustrate the isSupplementaryCodePoint() method
import java.lang.*;

public class gfg {

    public static void main(String[] args)
    {

        // Creates 2 int primitives c1, c2 and assign values
        int c1 = 0x45ffd, c2 = 0x004ca;

        boolean bool1 = Character.isSupplementaryCodePoint(c1);
        boolean bool2 = Character.isSupplementaryCodePoint(c2);

        String str1 = "c1 represents a supplementary code point is " + bool1;
        String str2 = "c2 represents a supplementary code point is " + bool2;
       
        // Displaying the result
        System.out.println(str1);
        System.out.println(str2);
    }
}

c1 represents a supplementary code point is true
c2 represents a supplementary code point is false
