public class Distance {

private Distance.MyPoint p1;
private Distance.MyPoint p2;

public Distance() {
}

public Distance(MyPoint p1, MyPoint p2) {
this.p1 = p1;
this.p2 = p2;
}

public double resultOfdistance() {
return Math.sqrt(
(p1.x - p2.x) * (p1.x - p2.x)
+ (p1.y - p2.y) * (p1.y - p2.y)
+ (p1.z - p2.z) * (p1.z - p2.z));
}

static class MyPoint {

public double x;
public double y;
public double z;

public MyPoint(double x, double y, double z) {
this.x = x;
this.y = y;
this.z = z;
}

public MyPoint(double x, double y) {
this(x, y, 0);
}
}

public static void main(String[] args) {
Distance.MyPoint p1 = new MyPoint(1, 2);
Distance.MyPoint p2 = new MyPoint(3, 4);
Distance d1 = new Distance(p1, p2);
System.out.println("平面两点间距离：" + d1.resultOfdistance());
Distance.MyPoint p3 = new MyPoint(1, 2, 3);
Distance.MyPoint p4 = new MyPoint(4, 5, 6);
Distance d2 = new Distance(p3, p4);
System.out.println("空间两点间距离：" + d2.resultOfdistance());
}
}

用公式是最简单的，不论平面两点还是空间两点，有坐标就行！代公式马上搞定！方法重载很简单，只是传参不一样…
