Description of code:

This program helps you to convert the character data into an integer type data. It defines a class name "CharToInt" and takes a character on the console. The given character is converted into an integer using the parseInt() method. It parses the string argument as a signed Integer value. Whenever the given character isn't numeric, it displays a message " Not a numeric!".

Here is the code of this program:


import java.io.*;

import java.lang.*;



public class CharToInt{

  public static void main(String[] args) {

  try{

  BufferedReader buffer = 

  new BufferedReader(new InputStreamReader(System.in));

  System.out.println("Enter a char:");

  String str = buffer.readLine();

  Character c = new Character(str.charAt(0));

  System.out.println("Char: "+ c);

  String s = c.toString();

  int i = Integer.parseInt(s);

  System.out.println("Integer: "+ i);

  }

  catch (Exception e){

  System.out.println("Not a numeric!");

  e.getMessage();

  }

  }
