two questions

[h_a25]

hey, how're u guys?

my instructor gave us an assignment and i really tried so hard but i couldn't write the codes well :/
the first task is about an IntegerSet class and the second about drawing a cube
here's the test class

public class IntegerSetTest {

public static void main(String[] args) {

IntegerSet s = new IntegerSet();
System.out.println(" s = " + s);
s.addElements(2);
s.addElements(20, 10, 100);
s.addElements(13, 20);
System.out.println(" s = " + s);

IntegerSet s1 = new IntegerSet(0, 3, 6);
s1.addElements(12, 20, 2000, 30, 31, 32, -11);
System.out.println(" s1 = " + s1);

IntegerSet s2 = new IntegerSet(10, 3, 16, 11, 21, 33, 99);
System.out.println(" s2 = " + s2);

if(s2.isElement(11))
System.out.println(" 11 belongs to s2");
else
System.out.println(" 11 does not belong to s2");

IntegerSet s3;
s3 = s1.union(s);
System.out.println(" s1 Union s = " + s3);
s2 = s1.intersection(s);
System.out.println(" s1 Intersection s = " + s2);

s2.addElements(2, 11, 7, 1100);
System.out.println(" s2 = " + s2);
s2.removeElement(20);
System.out.println(" s2 = " + s2);

}

}
and here's the outputs pic

Do you have a specific question that we can answer?

[h_a25]

well not really but the first task i should write IntegerSet class makes the IntegerSetTest class works and give the output in the pic icontains a constructor takes ellipsis parameter and the functions addElements, union and intersection
and the second task i should write a program to draw a cube like the one showing in the pic

OK, well best of luck with this project. Please come on back if you get stuck and have any specific questions that we can help you with.

We'd love to, but you've yet to ask an answerable question, and without a question, all this thread will consist of will be you expressing your frustration and us telling you that there's nothing we can do. No one is of course going to do this for you, and we'd love to help explain things and clarify misconceptions, but we have no idea where your problem is, what you understand, what you don't understand, etc. If you're totally lost, please look over this link -- So, You Need to Write a Program but Don't Know How to Start

That cube drawing doesn't look like it's a perspective projection; if it's an orthogonal projection it's easy: draw two squares and four lines between the corner points. For that set problem you can use a Set<Integer> or a BitSet (the API documentation is your friend).

kind regards,
