How to convert char value to int value in Java

The Apache Commons Lang library provides the method CharUtils.toIntValue() to convert a char value to an int value it represents. The method only supports the input char value range from ‘0’ to ‘9’ otherwise it throws a java.lang.IllegalArgumentException exception.

You can learn how to use the CharUtils.toIntValue() method with the following example code.

ConvertCharToInt.java

import org.apache.commons.lang3.CharUtils;

public class ConvertCharToInt {
    public static void main(String... args) {
        char charValue = '5';

        int intValue = CharUtils.toIntValue(charValue);

        System.out.println("Converted int value: " + intValue);
    }
}

Converted int value: 5

Happy Coding 😊
