oh are u reading complete string at a time or you want to read charector by charector

[kachkaha]

the code is as following
public static void Main() {
char ch;
do
{
ch = (char) Console.Read(); // get a char
Console.WriteLine(ch);
}
while(ch != 's' && ch != 'g' && ch != 'l');



}

public static void Main() {
char ch;
do
{
ch = (char) Console.Read(); // get a char
Console.WriteLine(ch);
}while(ch != 's' && ch != 'g' && ch != 'l');


}
}

The code posted thus far won't work, but what follows is a rough framework that will at least get you started. Hopefully.

public class MyApplication {
    public MyApplication() {
    }

    public static void main(String[] arguments) {
        MyApplication application = new MyApplication();
        application.start();
    }

    public void start() {
        java.io.Reader reader = new java.io.InputStreamReader(System.in);
        while (true) {
            int input;
            try {
                input = reader.read();
            } catch (java.io.IOException ioe) {
                System.out.println("An unexpected error occurred whilst reading input.");
                return;
            }

            switch (input) {
            case 'e':
                return;
            case 'g':
                /* ... */
                break;
            case 'l':
                /* ... */
                break;
            case 's':
                /* ... */
                break;
            default:
                /* ... */
                break;
            }
        }
    }
}
