r.nextInt() will return some random number that is a valid integer. That's from -2^32 +1 to 2^32 -1 I think. However, you could keep it as it but do this
int k = Math.abs(r.nextInt()) % 10;
...
Array indexes aren't valid, unless your variable happens to be of type Object, then it could be I think, if you initialized it as such, for regular int type.
Try using a different variable than...
The user presumably means that the code works, but they don't know the logic or it or why it is what it is.
The game goes on forever. You don't seem to have a thing that will end it.
Never mind. That was a spammer. Using AI stuff to copy posts, and it copied your first line, and post semi-relevant stuff, along with possibly links or stuff. That user has been banned.
Anyway,...
The Random's nextInt() could return negatives. However, this might work for you.
r.nextInt(Integer.MAX_VALUE)%10;
However, if that generated 1000 and then 100, it would both go to 0 with that...

Should have realized that. (Probably would have if I wasn't sleep deprived.)
Actually, you might possibly be able to use a for loop for that one, though the while should be kept as well.
for (int k = 1; k <=10; k++)
{
if ( n < 0.1k) count(k-1)++;
}

Arrays are a collection of similar, to an extent, an Object array could hold anything for instance, types.
It has int indexes and would, assuming it was already intiialized, and assuming you...
It appears that you're incrementing i several times in the same iteration, hence it's exiting quicker. If all of them are occurring under the same condition, then combine them under the same if...
I did have such a test program. However, the results, which did point at what copeg was saying, conflicted with that I had long believed to be true about abstract, that is that I thought I needed at...
No it's not inheritance. If anything, it's composition (or aggregation) hence the thread title.
Thanks. However, it appears it's a Model-T style thing, not that I have to choose black, but that I can't have one JMenu with a Red selection and another, in the same program, with a Green...
It seems to do this every single solitary time so I think I can make a shorter version of it that will show what's going on.

You could always have both.
Create a second one that will initialize your current object to the values of the parameter object.
Use getters and setters, like setLength(), setWidth(),...
Go to forum and then there should be a bunch of forums. Like What's Wrong with my code? Java Theory and Questions, etc.
I'm a bit confused here, unless there are two level variables, but is that java statement legal? It's declaring a variable and then initializing it to itself plus one. I'm not sure if that will...
An SSCEE? I was asking pretty much how a class could be abstract without any abstract methods or unimplemented interface methods.
Also, another thing, I can sub that class so far and only have...
It implements, I think, all the methods from the interface Border. Yet it's abstract. How is that possible? I thought that in java an abstract class had to have at least one abstract method. I...
JTextField field = new JTextField(20);
field.setText("Button 1");
That is because you are referring to the field object you created that only has the scope of the ActionListener.
Also,...
Put this line before your actionListeners are coded.
JTextField field = new JTextField(20);
Right now field is null when it's going into them.
Try changing it, in the TextBook class, to
implements Comparable<TextBook> and see if that works.
An Item might not necessarily be a TextBook. If you also had a class that extended...
Any reason why both Item and Textbook are both implementing Comparable<Item>?
I think that it's
Comparable<T>
so if you also want to have TextBook implement Comparable, then I think it...
You posted the GUI class twice it looks like.
