Re : I need Help

OK, let me illustrate it:

1. void setup()
2. {
3.   println(getItems()[2]);
4.   exit();
5. }
6.  
7. int[] getItems()
8. {
9.   int[] items = { 0, 1, 2, 3, 4, 5 };
10.   return items;
11. }

getItems() returns an array, and we can pick one item from it directly.
The return value of a method can be used immediately.
This allows some nice tricks, like chaining calls:

1. StringBuilder sb = new StringBuilder("Initial ");
2. sb.append("one ").append("two ").append("Last");

because append() just returns this.
