// DIS's super-duper simplified version of code for obtaining user-input.
// Spring 2001

// Load Java's I/O facilities:
import java.io.*;

public class UserIO {
    
    // $main$ must "throw" an exception if input is illegal:
    public static void main(String[] args) throws IOException {

	// Create object $in$ that allows you to prompt user for input:
	BufferedReader in = new BufferedReader
	    (new InputStreamReader(System.in)); 
	
	// Read strings:
	System.out.print("Enter a string: ");
	String s = in.readLine();
	System.out.println("You entered "+s);

	// Enter integer:
	System.out.print("Enter an integer: ");
	int n = Integer.parseInt(in.readLine());
	System.out.println("You entered "+n);

	// Enter double:
	System.out.print("Enter a double: ");
	double x = Double.valueOf(in.readLine()).doubleValue();
	System.out.println("You entered "+x);

    }
