java.lang.Character isValidCodePoint(int codePoint)
Description
The isValidCodePoint(int codePoint) method of Character class is static thus it should be accessed statically which means the we would be calling this method in this format:
Character.isValidCodePoint(int codePoint)
Non static method is usually called by just declaring method_name(argument) however in this case since the method is static, it should be called by appending the class name as suffix. We will be encountering a compilation problem if we call the java isValidCodePoint() method non statically.
Method Syntax
public static boolean isValidCodePoint(int codePoint)
Method Argument
| Data Type | Parameter | Description |
|---|---|---|
| int | codepoint | the Unicode code point to be tested |
Method Returns
The isValidCodePoint(int codePoint) method of Character class returns true if the specified code point value is between MIN_CODE_POINT and MAX_CODE_POINT inclusive; false otherwise.
Compatibility
Requires Java 1.5 and up
Java Character isValidCodePoint(int codePoint) Example
Below is a simple java example on the usage of isValidCodePoint(int codePoint) method of Character class.
package com.javatutorialhq.java.examples;
/*
* This example source code demonstrates the use of
* isValidCodePoint(int codePoint) method of Character class.
*/
public class CharacterIsValidCodePointExample {
public static void main(String[] args) {
// initialize codepoints
int codepoint1 = 12;
int codepoint2 = 5114232;
// check the codepoints are valid
boolean result1 = Character.isValidCodePoint(codepoint1);
boolean result2 = Character.isValidCodePoint(codepoint2);
// print the result
System.out.println("Is codepoint "+codepoint1 +
" is a valid codepoint?"+result1);
System.out.println("Is codepoint "+codepoint2 +
" is a valid codepoint?"+result2);
// print the minimum and maximum codepoint
System.out.println("Minimum codepoint:"+Character.MIN_CODE_POINT);
System.out.println("Maximum codepoint:"+Character.MAX_CODE_POINT);
}
}
