Android: Class problem

Question

I've created a class called website, and want to access it like a variable so I can update values to it, probably better explained below:

Website w = new Website();
w.URL="stackoverflow.com";

Here's the code for the class:

class Website {
 public String URL;
 public Website(){
 URL = "";
 }
}

I would also like to add a method such as this:

public long save() {
 return db.save(URL);
}

This (the method) isn't working for me at the moment

• yogsma: I changed the class name from Credential to Website.
• Todd Davies: Thanks, but the problem still remains...
• yogsma: What is the error you are getting?
• Todd Davies: A null pointer exception
• Todd Davies: Other classes I've seen seem to use static, but this makes me unable to change the URL.

Answer 1

I would do it more OO way, hiding this URL variable from outside and letting change it's value from getter and setter methods. You can try this, maybe this will help.

In Website class

public class Website {
 private String URL;
 public Website(){
 this.URL = "";
 }
 public void setUrl(String url) {
 this.URL = url;
 }
 public String getUrl() {
 return this.URL;
 }
 public long save() {
 return db.save(this.URL);
 }
}

And then call it

Website w = new Website();
w.setUrl("http://www.stackoverflow.com");
long someLongValue = w.save();
