Read from keyboard(Console application)

[serge]

Hi everyone,
I have been trying to read a string of characters from the keyboard but I
keep getting an IOException. I am attaching the code. Any help would be very
appreciated thanks.

/*
This class is to be used as new readline method
*/
import java.io.*;
class ReadInput
{
public static void main(String[] args)
{
InputStreamReader reader = new InputStreamReader(System.in);
BufferedReader in = new BufferedReader(reader);

ReadInput r = new ReadInput();
try{
r.readline(in);
}
catch (IOException e)
{
System.out.print("\n Exception caught \n");
}

}

public void readline(BufferedReader b)throws IOException
{
String input ="";
//Buffer is empty at the moment
while(true)
{
System.out.print("Echo<");
input = b.readLine();
// else
{
if ("".equals(input))
{
System.out.println("End");
break;
}
else
{
if("OK".equals(input))
{
System.out.println("OK command received ...");
}
}
System.out.println("Echo>" + input.toUpperCase());
}
}
//in.close();

}
}

Your code works for me.
Note that BufferedReader's readLine() will return null if the end of the
stream has been reached, so you should check for that.
What IOException are you getting?
where you have
System.out.print("\n Exception caught \n");
you might also add
e.printStackTrace();
so you can evaluate the error.
