Java objects

Can someone explain to me what is this :

[code] public Knapsack[b](Item[] items)[/b]
[/code]

then the use of that is like this Knapsack k = new Item(“Pen”, 15)

how do I get only those two arguments that are passing in a different class as arguments so I can use only PEN and only number 15 separately in my constructor?

First, you need to create an array of Item objects:

``<i>
</i>Item[] items = new Item[2];<i>
</i>`</CODE>
This declares a variable named <C>items</C> that references an array of 2 item objects (that don't exist, yet).

Then you can put Item objects in the array with:
<CODE>`<i>
</i>items[0] = new Item("Pen", 15);
items[1] = new Item("Paper", 30);<i>
</i>`</CODE>
Now, you can create a Knapsack object with the array of items:
<CODE>`<i>
</i>Knapsack myKnapsack = new Knapsack(items);<i>
</i>``

Success!
