Help with getting an array from a method..

[Ashley Carey]

Ok so, i have this code where i have 1 button linked to a method to calculate something(the method is in another class) and it returns an array with what it was supposed to calculate. then i have another method which needs to display all of it.. the thing i need help with is getting the thing it returned from 1 method into another.. i cant figure it out. .is there anything you can type to just make it read variables from other methods without having to make it return something?

      if (menuItemObj == strategy0)
  {
  double[][] strat0;
  int weeks;
  int total;
  total = p.gettotal();
  weeks = weeksField.getNumber();
  if(total == 0)
  {
  messageBox("Please add a product first");
    }
  if (weeks <= 0)
  {
      messageBox("Please Enter a number higher than 0 in the week field");
      }
      else
      {
      weeks = weeksField.getNumber();
      strat0 = p.getStrategy0(weeks);
      }
      }
      if (menuItemObj == display0)
      {
 
  }  

this is the code.. the bottom one is the button that i need to use to display it.. i need to get the array that gets returned.. and put it into that second method....
