    <p>So essentially what I want to do is to be able to:</p> <pre><code>class MainFile { public static void main(String args[]){ class2 TEObject = new class2(); int var1 = 1; int var2 = 1; int var3 = 1; int sc = 1; TEObject.method1(sc, var1, var2, var3); double[][] somearray = class2.out(somearray); System.out.println(somearray); } } </code></pre> <p>and here is the second class:</p> <pre><code> public class class2 { private double Mult; public double method1(int sc, int var1, int var2, int var3) { double[][] somearray = {{1,1,1,1,1,1,1,1,1,1,1,1}, {1,0.5,1,0.5,0.5,1,1,2,2,0.5,1,2}, {1,2,0.5,1,1,0.5,1,1,0.5,1,1,2}, {1,2,1,0.5,0.5,1,1,0.5,2,1,0.5,2}, {1,2,2,2,0.5,1,0.5,1,1,0.5,1,0.5}, {1,1,0.5,1,1,0.5,2,0.5,1,2,2,0.5}, {1,0.5,1,0.5,1,1,0.5,2,0.5,2,2,1}, {1,0.5,2,2,2,2,0.5,0.5,0.5,1,1,0.5}, {1,1,1,0.5,2,2,1,2,0.5,0.5,0.5,1}, {1,1,0.5,1,2,0.5,2,0.5,1,0.5,2,1}, {1,1,2,1,0.5,0.5,0.5,1,2,2,0.5,1}, {1,0.5,0.5,2,1,2,2,1,1,1,0.5,0.5}, }; Mult = somearray[sc][var1]*somearray[sc][var2]*somearray[sc][var3]; return Mult;//This needs to be returned for other methods in class2 } public static double[][] out(double[][] somearray){ return somearray; } //Some more methods go here </code></pre> <p>The problem I have here is that it asks me to put in a value when I try and call the method it says that the type is not applicable for the arguments. I can't put null there or else it will just print null.</p> <p>Failing this I essentially want a way to be able to output from a class to my main class so that I can manipulate the array within the main class.</p> <p>EDIT: I've updated the classes so they're more clear as to what I'm trying to do.</p>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
