    Default Having a hard time figuring this out! Please help.

    Hey... So I've got a couple problems that I can't find anywhere online or in my textbook and I'm pretty sure their simple if the right eye sees them. I obviously don't have the right eye for it! I'm just wondering if anybody could provide me some direction or show me how this could be done so that I could look at the code and learn from it. I'm very visual so being able to look at a completed or near completed product could definitely help. I'm trying to teach myself java and when I hit a speed bump like this it gets pretty frustrating. If possible... Please help! Thank you.

    I believe it's supposed to have a main class that links all these together.

    Integer Math
    Create a class which stores an integer and answers questions about it. The class should have a constructor which takes the integer to analyze. You must determine the accessibility of the stored integer, should it be public, private or final? The object must answer the following questions:

    is the number odd or even?
    is the number divisible by 3? (3,6 & 9 are, 22 is not)
    is the number divisible by a given (parameter) integer?
    (12 is a power of 4, 29 is not a power of 5)
    An Unchangeable Point
    This class represents a point in 2D space, that once made cannot be changed.

    I should be able to read the x and y values, but not change them.
    The values will be integers.
    I need to determine the distance from another point.
    For example: (1,1) is ~4.2426 away from (4,5)
    I need to be able to get a point that is offset from the original
    For example: (1,3) offset by (-1, -1) is (0,2)
    Circle Math
    This class represents a circle in 2D space and does calculations on it.

    It can be made with a point (see previous part) and a radius.
    I need to be able to ask the objects for their area and perimeter.
    For example: a circle with radius 3 has an area of ~28.2743
    For example: a circle with radius 3 has a perimeter of ~18.8495
    It should be able to determine if another point is inside it
    For example: (1,3) is inside a circle at (1,1) with a radius 4

    If you want us to create the code for you, you're in the wrong forum. We try to help if you're stuck in your own code but I don't see any code anywhere; give it a try and tell us what's troubling you. This must be homework so if we did it for you, it would be cheating, wouldn't it?

    kind regards,
