converting an algebraic equation to Java

[fsuarjun03]

How do I go about converting the Pythagorean Theorem into Java?

is it a little like this? I'm just lost on how to get put square root into that formula. What is the proper way to do it?


z = (x * x) + (y * y)

Check out this class

Ahhh. That helps a bit but how do I put it all together.


I am trying to create a class to solve for all parts of Pythagoreans Theorem. I am starting with solving for the sides and then moving on to solving for the angles. I'm just going to show you what I have so far. I know its not right but here.

public class Pythagoras
{
    private int x, y, z;
    public Pythagoras(int x, int y, int z)
    {
            x = (int) 1;
            y = (int) 1;
            z = (int) 1;
    }
    public void calculate()
    {
        z = ((x * x) + (y * y));
        x = ((z * z) - (y * y));
        y = ((z * z) - (x * x));
    }
    public int getSideX()
    {
        return x;
    }
    public int getSideY()
    {
        return y;
    }
    public int getSideZ()
    {
        return z;
    }
}

Where should the following go in the above section? Does it go in there or should it be in the Test Class?

public static double sqrt(double a)

I am a newbie and I'm trying to teach myself. I joined the forum because I figured that all you guys know a lot of Java and I could learn from all the problems that everyone else comes across and maybe even get to the point where I could help other people.
