read data from keyboard

[Andrew Parker]

Hi,
I want to let user input a string, display it and then terminate the program.
I have the following code:
import java.io.*;
public class MyCat {
public static void main (String args[])
throws IOException {
int b;
while ((b = System.in.read()) != -1) {
System.out.print((char)b);
}
System.out.println();
}
}
The result is that it requires input continueously without termination.
I changed it:
import java.io.*;
public class MyCow {
public static void main (String args[])
String b;

System.in.read(b);
System.out.print(b);
}

It shows a lot of errors. I don't understand why do I need to use Exception in the first case, the while loop is to read the char one by one.
In C++, I just cin >> a; and cout << a; to get and display the string a. How should I do it in Java?

Thanks
Andrew

Hi Andrew,
The code below might be what you are looking for.

import java.io.*;
public class MyCow 
{
  public static void main (String args[]) 
  {
    String b;
    BufferedReader d = new BufferedReader( new InputStreamReader( System.in ));
    System.out.print( "Type here: " );
    try
    {
      b = d.readLine();
      System.out.print( b );
    }
    catch( IOException e ) {};
  }
}

You should usually use BufferedReader to handle input from the console.

Manfred

Hi,
Thanks a lot and I will re-read the BufferReader method again.
Have you used any IDE such as JBuilder or VisualAge? Which one can create the AWT-GUI like VB6?

Andrew,
You can use Netbeans (www.netbeans.org), Forte (www.sun.com/forte), JBuilder (www.jbuilder.com), or any other Java IDE to develop GUI forms.
Of course, if you can also get the same results using a plain vanilla text editor, but you'll have to brush up on Swing/AWT APIs for that. It's good practice though, and fear not, the Java APIs for GUIs are MUCH easier than Windows APIs!

Reuben.
