In Java, the value contained in one data type can be converted to another data type based on conversion requirements, the same holds true for char to int conversion. Converting a char to an int is equivalent to finding the ASCII value of the given character. In this article on “Convert Char to Int in Java”, we will learn how to convert a char to int with the help of examples.
The topics discussed in this article are:
Data types are the storage containers that store the value of a particular type like integers, chars, floating values, Boolean values, etc. A data type specifies the type of value a variable has and the type of relational, mathematical or logical operations that can be applied to it without causing an error.
The choice of data types for a particular variable depends on multiple factors. In most cases, the decision is intuitive. For example,
Filename: CharToIntExample.java
Code:
public static void main(String args[]){ char c='Z'; char c1='9'; int a=c; int b=c1; System.out.println(a); System.out.println(b); }}
Compile by : javac CharToIntExample.java
Run by : java CharToIntExample
Filename: CharToIntExample1.java
Code:
public class CharToIntExample1{ public static void main(String args[]){ char c='9'; int a=Character.getNumericValue(c); System.out.println(a); }}
Compile by: javac CharToIntExample1.java
Run by: java CharToIntExample1
Java char to int Example: String.valueOf() :
Filename: CharToIntExample2.java
Code:
public class CharToIntExample2{ public static void main(String args[]){ char c='8'; int a=Integer.parseInt(String.valueOf(c)); System.out.println(a); }}
Compile by: javac CharToIntExample2.java
Run by: java CharToIntExample2
