用Java编写一个应用程序，该应用程序实现：
在二维平面，有一组随机点组成的三角形，画出三角形，并求出各个三角形的外接圆圆心，
将三角形的圆心存入数组，并画出外接圆心组成的三角形同时将前面画出的三角形消去

========================三角形的外接圆心==========================
public class Triangle {
// 三角形的三个顶点
private Point2D.Double p1;
private Point2D.Double p2;
private Point2D.Double p3;

public Triangle(Point2D.Double p1, Point2D.Double p2, Point2D.Double p3) {
this.p1 = p1;
this.p2 = p2;
this.p3 = p3;

dis12 = distenceOfPoints(p1, p2);
dis23 = distenceOfPoints(p2, p3);
dis31 = distenceOfPoints(p3, p1);
}
// 两点之间的距离
public static double distenceOfPoints(Point2D.Double p1, Point2D.Double p2) {
return Math.sqrt((p1.x - p2.x) * (p1.x - p2.x) + (p1.y - p2.y) * (p1.y - p2.y));
}
// 外切圆圆心

public Point2D.Double outerCenter() {
double x1 = p1.x;
double x2 = p2.x;
double x3 = p3.x;
double y1 = p1.y;
double y2 = p2.y;
double y3 = p3.y;

double x = ((y2 - y1) * (y3 * y3 - y1 * y1 + x3 * x3 - x1 * x1) - (y3 - y1)

* (y2 * y2 - y1 * y1 + x2 * x2 - x1 * x1))

/ (2 * (x3 - x1) * (y2 - y1) - 2 * ((x2 - x1) * (y3 - y1)));

double y = ((x2 - x1) * (x3 * x3 - x1 * x1 + y3 * y3 - y1 * y1) - (x3 - x1)

* (x2 * x2 - x1 * x1 + y2 * y2 - y1 * y1))

/ (2 * (y3 - y1) * (x2 - x1) - 2 * ((y2 - y1) * (x3 - x1)));

return new Point2D.Double(x, y);

}

是代码有问题还是？

贴个错误啊？
