Character.isSupplementaryCodePoint() Method in Java ❤️

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

Syntax:

public static boolean isSupplementaryCodePoint(int codePoint)

Parameters: The codePoint of integer type refers to the character (Unicode code point) that is 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.

Below programs illustrate the Character.isSupplementaryCodePoint() method:

Program 1:

// 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); 
    } 
} 

Output:

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

Program 2:

// 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); 
    } 
} 

Output:

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