Help with BufferedStream in MacOs

Question

I just started Learning java using mac and the MRJ 2.25
and MRJ SDK 2.2. I'm tryint to write some very basic Io stuff and it just isn't working. Everything works fine(out put, arrays, arithmatic) except for input. my code is as follows
import java.io.*;
public class test
public static void main(String [] args) throws Exception
InputStreamReader input = new InputStreamReader (system.in);
BufferedReader in = new BufferedReader(input);
System.out.println("enter a string: ");
String x = in.readLine();
System.out.println(x);
the output for this is : enter a string:
null
and then it terminates. it never lets the user input and seems to be skipping the readLine command alltogether and not initilizing x. I have no clue how to fix this. Is this just a mac thing? please help

Try this:
import java.io.*;
public class IoTest {
    public static void main(String [] args) throws Exception {
        InputStreamReader input = new InputStreamReader(System.in);
        BufferedReader in = new BufferedReader(input);
        System.out.println("enter a string: ");
        String x;
        while ((x = in.readLine()) != null) {
            System.out.println(x);
}
