Write a program to find ASCII value.
public class AsciiValueCharacter { public static void main(String[] args) { char ch = 'a'; int ascii = ch; // You can also cast char to int int castAsciichar = (int) ch; System.out.println("The ASCII value of " + ch + " is: " + ascii); System.out.println("The ASCII value of " + ch + " is: " + castAsciichar); } }
Output
The ASCII value of a is: 97 The ASCII value of a is: 97
In the above program, we define character variable using char keyword and variable ch is having value of ‘a’. A character is defined using single quote(‘ ‘ ).
Obviously, ASCII value of any character will be an int, so we need to define that in a int variable ie. int ascii = ch . After that, JVM internally converts the character value to its corresponding ASCII value.
the line int castAsciichar = (int) ch is purely casting concept. In other words, Casting is a concept of converting one type into other type. For instance, char variable is converted to int type here.
