Troubleshoot Help: Darts Hit or Miss using a (for) loop.

Hello, I have an assignment for my AP Computer Science class that is giving me some troubles. I have tried to compile the program, but I have a few pesky bugs that I can't seem to get rid of. I will include the code as well as the location and nature of my error messages. The basic idea of the program is to have darts thrown within a square with a side length of 2. Darts which fall within a circle of radius 1 count as a "hit", and darts outside of this circle count as a "miss". I decided to simplify the program by only having darts thrown in the first quadrant. I am not so much concerned with the results I get from the program as I am with just getting it to compile. Please leave comments with any suggestions you have or if you find any mistakes.

Thank you in advance,

public class Pi
{

class Pi(double r)
{

double radius= r;

}

public void tossDart()
{

int hit= 0;
int miss= 0;

for (i=1; i<=1000; i++)
{

double x= Math.random();
double y= Math.random();
double t= Math.sqrt(Math.power(x,2)+Math.power(y,2));

if (t<=radius)
{

hit++;

}
else
{

miss++;

}

}
}

public void getData()
{

System.out.println("The number of hits: "+hit);
System.out.println("The number of misses: "+miss);

}

private int hit;
private int miss;
private double radius;
private double x;
private double y;
private double t;

Look up your book or tutorial on how to create constructors. They don't start with the key-word "class". That's only used at the start of the class itself (as you've done at the very top of your program code.

You were correct in your above suggestion. Thanks!
