The Character.isValidCodePoint() is an inbuilt method in java that determines whether the specified code point mentioned in the parameter is a valid Unicode code point value or not.
Syntax:
public static boolean isValidCodePoint(int codePoint)
Parameters: The parameter codePoint is of Integer datatype and refers to the unicode code point that is to be tested.
Return Values: This method returns true if the specified code point value is between MIN_CODE_POINT and MAX_CODE_POINT inclusive, false otherwise.
Below Programs illustrates the use of Character.isValidCodePoint() method:
Program 1:
// Java program to demonstrate the// Character.isValidCodePoint() methodimport java.lang.*;  public class gfg {      public static void main(String[] args)    {          // Create 2 int primitives c1, c2 and assign values        int c1 = 0x0125, c2 = 0x123fff;          boolean bool1 = Character.isValidCodePoint(c1);        boolean bool2 = Character.isValidCodePoint(c2);          String str1 = "c1 is a valid Unicode code point is " + bool1;        String str2 = "c2 is a valid Unicode code point is " + bool2;          // Print bool1, bool2 values        System.out.println(str1);        System.out.println(str2);    }} |
Output:
c1 is a valid Unicode code point is true c2 is a valid Unicode code point is false
Program 2:
// Java program to demonstrate the// Character.isValidCodePoint() method import java.lang.*;  public class gfg {      public static void main(String[] args)    {          // Create 2 int primitives c1, c2 and assign values        int c1 = 0x0128, c2 = 0x123ddd;          boolean bool1 = Character.isValidCodePoint(c1);        boolean bool2 = Character.isValidCodePoint(c2);          String str1 = "c1 is a valid Unicode code point is " + bool1;        String str2 = "c2 is a valid Unicode code point is " + bool2;          // Print bool1, bool2 values        System.out.println(str1);        System.out.println(str2);    }} |
Output:
c1 is a valid Unicode code point is true c2 is a valid Unicode code point is false
