step 1: Read a character

step 2: Cast it into byte and store in b

step 3: Print b

step 4: Exit

Here is the Java Example for the program ASCIIValue: 

import java.io.*;

public class ASCIIValue
{
public static void main(String args[])throws Exception
       {
InputStreamReader is=new InputStreamReader(System.in);
BufferedReader br=new BufferedReader(is);
System.out.println("Enter A character and Find Out The Ascii value");
byte b=(byte)System.in.read();
System.out.println(b);
       }
}

get Ascii value from character
