To input a character in Java

[shiv4singh]

Hi There
Can anyone write me a program in which a character input is taken from console? If I am executing a program using do..while() loop. Is there any way through which I could clear the contente of console each time when execution takes place.

Thanks n Regards,

Write the code yourself. We are only here to help you write the code. Clearing the console is not something you want to do now in java. Your best bet is to write yourself a clrscr method which simply prints blank lines to the console until there's nothing showing.

Well I wrote the code and used read() method but it was generating IOException. Below is the code that I had coded :

import java.io.*;
import java.io.Reader;
public class test
{
public static void main() //throws Exception
{
BufferedReader buf = new BufferedReader(new InputStreamReader(System.in));
System.out.println("Enter a Character :");
try
{
//char ch= (char)(System.in.read());
char ch = (char)(buf.read());
}
catch(IOException ei)
{
System.out.println("Error");
}
}
}

Use Scanner for taking input. There's a thread in this forum now that's discussing that.

Instead of just printing "Error" do this: "e.printStackTrace()" and see the reason
for that ugly exception in all its glory.
