Convert Character into Integer
In this section, you will learn to convert the character
into a integer. The java.lang package convert provides the facility to
convert the character data into an integer type.
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();
}
}
}
