Calling a method from an object

Question

Hi guys,
I'm trying to use the "testTemperature" method to access the object type "WeatherStation" (already created in my project) and return its initial temperature value.
I keep getting an error message when i do it. Can someone tell me where i'm going wrong?
public class Reporter
    // instance variables
    private WeatherStation ws;
    private WeatherReport wr;
    /** Constructor for objects of class Report
    public Reporter()
        ws = new WeatherStation("Tropical");
        wr = new WeatherReport();
    /** Returns initial temperature value
    public int testTemperature()
        return WeatherStation.temperature;
     * Constructor for objects of class Report
    public Reporter(String where)
        ws = new WeatherStation(where);
        wr = new WeatherReport();
}

You are trying to access temperature statically. You have created a WeatherStation object so you should accessing temperature via that object instead.Yeah, that was what i wanted to do.
I have now sorted that out now.
I've got a problem though.....
When i compile, it says there is no syntax error, but when i run the method, it gives me this error message ---> http://i36.tinypic.com/14ne3wl.jpg
Here's my code....
public class Reporter
    // instance variables
    private WeatherStation ws;
    private WeatherReport wr;
    private WeatherStation temperature;
    /** Constructor for objects of class Report
    public Reporter()
        ws = new WeatherStation("Tropical");
        wr = new WeatherReport();
    /** Returns initial temperature value
    public int testTemperature()
        return temperature.getTemperature();
     * Constructor for objects of class Report
    public Reporter(String where)
        ws = new WeatherStation(where);
        wr = new WeatherReport();
}Anyone got an idea where i'm going wrong?
