getting attributes from one class to another in 2 different .java files

[Mr tuition]

Hi there,

I have run in to a little trouble which should be quite simple

I have 2 java files: one that loads the data, the second that displays data in a jframe

how can I pass the data from one to another?
in file ReadXML.java:

PHP Code:

public class ReadXML {
    public ReadXML() {
        init();
       // Reads in the data from XML
      // sets StrAllData
}
private String StrAllData; 


in file Cpass.java:
public class Cpass extends javax.swing.JFrame {

PHP Code:

    /** Creates new form Cpass */
    public Cpass() {
        initComponents();
   // on pushing a button new ReadXML();
   // need a way to grab  StrAllData
  // can then set a text field to this 
  }

I have set StrAllData to puclic and tried to get this via ReadXML.StrAllData, but it tells me non-static variable can not be refrenced from a static context:
jTextArea13.setText(ReadXML.StrAllData);

[Mr tuition]

This works:

In ReadXML create a getter for the StrAllData like this:

public String getStrAllData() {
return this.StrAllData;
}



In Cpass call getStrAllData on the ReadXML instance, for example:

ReadXML reader = new ReadXML();
String xmlContent = reader.getStrAllData();
