Character Integer Values Java

In this tutorial, we covered four different approaches to convert char to int in Java, Using ASCII Values, Integer.parseInt method, Character.getNumericValue method and Subtracting '0'

Given a char value, and our task is to convert it into an int value in Java. We can convert a Character to its equivalent Integer in different ways, which are covered in this article.

Learn how characters are internally represented in Java and how we can convert an int to a char and back.

To parse an integer value from a char in Java, you can use the Character.getNumericValue method. This method returns the numeric value of the specified char, or -1 if the char is not a digit. For example

In this tutorial we will learn the different ways to convert values of primitive data type char to int in Java along with FAQs and examples.

Learn how to use the Java Character getNumericValue method to convert a character into its numeric value. Explore examples and syntax.

In this program, we will learn to convert the character char type variable into an integer int in Java.

The ASCII table is arranged so that the value of the character '9' is nine greater than the value of '0' the value of the character '8' is eight greater than the value of '0' and so on. So you can get the int value of a decimal digit char by subtracting '0'. char x '9' int y x - '0' gives the int value 9

Note, that this works for getting int values exclusively for integer characters! If you subtract '0' from, say, 'A', the method will simply return the difference between the ASCII codes of zero and the letter A.

Converting Characters to Integers is essential in programming, whether it is users' input or extracting values from strings. Every programming language has different techniques to handle the conversion of these lines. In this article, we will explore how to convert characters to integers in several popular programming languages C, C, Java, Python, C, and JavaScript.
