Calling another java file

Question

I have a main class ( packet.java for example) and I need to call another file (filter.java) to display a dialog box. Both files are in the same package, but all I want to do is when a button is clicked in packet.java, I want it to display the dialog box in filter.java.

Answer 1

example:
you have to source files with one class in each:
file1:
public class HelloWorld {
   private String helloText = null;
   public HelloWorld(String text) { // constructor
      helloText = text;
   public String getMessage() {
      return "Hello " + helloText;
}file2 (which accesses the class in file1):
public class Foo {
   public static void main(String[] args)  {
      for(int i=0; i<args.length; i++) {
         HelloWorld hello = new HelloWorld(args);
System.out.println(hello.getMessage());
if you run the app like this:
java Foo blackieul Thofthe output will be:
Hello blackieul
Hello ThofPlease specify your problem more detailed - e.g. post an exception message or the fragment of code where you don't know what to do...
