java.lang.Character isUnicodeIdentifierPart(int codePoint)
Description
A character may be part of a Unicode identifier if and only if one of the following statements is true:
- it is a letter
- it is a connecting punctuation character (such as ‘_’)
- it is a digit
- it is a numeric letter (such as a Roman numeral character)
- it is a combining mark
- it is a non-spacing mark
- isIdentifierIgnorable returns true for this character.
The isUnicodeIdentifierPart(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.isUnicodeIdentifierPart(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 isUnicodeIdentifierPart() method non statically.

Java Character isUnicodeIdentifierPart(int codePoint) Example
Below is a simple java example on the usage of isUnicodeIdentifierPart(int codePoint) method of Character class.
package com.javatutorialhq.java.examples;
/*
* This example source code demonstrates the use of
* isUnicodeIdentifierPart(int codePoint) method of Character class.
*/
public class CharacterIsUnicodeIdentifierPartCodepointExample {
public static void main(String[] args) {
// initialize a codepoint
int codepoint = 89;
/*
* check if the specified character (Unicode code point) is
* permissible as part of a Unicode identifier.
*/
boolean checkBool = Character.isUnicodeIdentifierPart(codepoint);
// print result
if (checkBool) {
System.out.print("User input '" + codepoint + "' is permissible as part "
+ "of a Unicode identifier");
} else {
System.out.print("User input '" + codepoint + "' is not permissible as part "
+ "of a Unicode identifier");
}
