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() methodimport 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() methodimport 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
