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:
import java.lang.*;
public class gfg {
public static void main(String[] args)
{
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;
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:
import java.lang.*;
public class gfg {
public static void main(String[] args)
{
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;
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
