Hi,,
I'm learning Java,, and I was trying to creat a function that performs
a three-level nested loop and returns a list of loop objects indicating
progress through the loop,,but when I ran this code:

[code snipped]

I got the following results,,

[loop.Loop@10b62c9, loop.Loop@82ba41, loop.Loop@923e30,
loop.Loop@130c19b, loop.Loop@1f6a7b9, loop.Loop@7d772e,
loop.Loop@11b86e7, loop.Loop@35ce36, loop.Loop@757aef,
loop.Loop@d9f9c3, loop.Loop@9cab16, loop.Loop@1a46e30,
loop.Loop@3e25a5, loop.Loop@19821f, loop.Loop@addbf1, loop.Loop@42e816,
loop.Loop@9304b1, loop.Loop@190d11, loop.Loop@a90653, loop.Loop@de6ced]

What results did you expect (this isn't a sarcastic or rhetorical
question -- I really don't know what it is you're trying to do)? Perhaps you
meant to override the toString() method? See

Please don't add your material at the top - its better to keep things in
order.

You are still calling the Loop object toString method, without having
supplied a toString override in the Loop class. Loop's immediate
superclass is Object, so you are using the Object toString method.

You need to add to Loop a method:

public String toString(){
// build the string you want to describe your loop object.
// return it.
}

Thanx for your message,, but shouldn't doLoops().get(i) return the
element of the index i in the list,, that's what i understood from the
java doc,, and I don't know how to build the string in the toString
method :s ,, can u help me further more,, Thanx once again

doLoops().get(i) will return the element at index i. the element at
index I is a "Loop" object, not an integer.

List<Loop> doLoops; // This declares a list of loops.

List<Integer> integers; // This is a list of Integer objects.
