string x=keyboard.readstring()

is not a standard java api. i think this is a third party. or your trying to copy the code in the book. try to create your input method for yourself. i;ll give you some pointer>

1: declare this

import java.io.*;

2: in your main method add some throw exception
public static void main(String s[])throws IOException { // begin main

3: wrap the class InputStreamReader in a BufferedReader

BufferedReader in = new BufferedReader(
new InputStreamReader(System.in));
4: use it.
System.out.println("Enter your number: " );
int number= Integer.parseInt(in.readLine());

String x= new BufferedReader(new InputStreamReader(System.in)).readLine();

Here it is in action:
This just reads one of text from the standard input (keyboard) and then prints it to standard output (screen).


import java.io.*;
class Test {
	public static void main(String[] args){
        try{
            String x= new BufferedReader(new InputStreamReader(System.in)).readLine();
            System.out.println(x);
        }catch(IOException ioe){
            System.err.println(ioe.getMessage());
        }
    }
}
