Java.lang.Character.isValidCodePoint() Method
Description
The java.lang.Character.isValidCodePoint(int codePoint) determines whether the specified code point is a valid Unicode code point value.
Declaration
Following is the declaration for java.lang.Character.isValidCodePoint() method
public static boolean isValidCodePoint(int codePoint)
Parameters
codePoint − the Unicode code point to be tested
Return Value
This method returns true if the specified code point value is between MIN_CODE_POINT and MAX_CODE_POINT inclusive, false otherwise.
Exception
NA
Example
The following example shows the usage of lang.Character.isValidCodePoint() method.
package com.tutorialspoint; import java.lang.*; public class CharacterDemo { public static void main(String[] args) { // create 2 int primitives cp1, cp2 int cp1, cp2; // assign values to cp1, cp2 cp1 = 0x0123; cp2 = 0x123fff; // create 2 boolean primitives b1, b2 boolean b1, b2; /** * check if cp1, cp2 are valid Unicode code points * and assign results to b1, b2 */ b1 = Character.isValidCodePoint(cp1); b2 = Character.isValidCodePoint(cp2); String str1 = "cp1 is a valid Unicode code point is " + b1; String str2 = "cp2 is a valid Unicode code point is " + b2; // print b1, b2 values System.out.println( str1 ); System.out.println( str2 ); } }
Let us compile and run the above program, this will produce the following result −
cp1 is a valid Unicode code point is true cp2 is a valid Unicode code point is false
