I keep getting errors in my main method... What am i doing wrong?public class midterm_1 {
public static void main(String[] args) {
midterm_1 c1 = new midterm_1 ();
System.out.println("Area is " + c1.getArea());
System.out.println("Perimeter is " + c1.getPerimeter());
System.out.println(c1.contains(3, 3));
System.out.println(c1.contains(new midterm_1()));
System.out.println(c1.overlaps(new midterm_1()));
}

this.radius =radius;
}

}
Explanation / Answer
please rate - thanks

the name of the class is Circle2D, not midterm_1, that is the major problem. I also made some other changes - I think I've highlighted them all
public class midterm_1 {
public static void main(String[] args) {
Circle2D c1 = new Circle2D (5.,6.,4);
System.out.println("Area is " + c1.getArea());
System.out.println("Perimeter is " + c1.getPerimeter());
System.out.println(c1.contains(3, 3));
System.out.println(c1.contains(new Circle2D()));
System.out.println(c1.overlaps(new Circle2D()));
}
}
