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.

        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);
    }
}
