public class TestCircle {
public static void main(String args[]) {
Circle c1 = new Circle(new Point(1.0, 2.0), 2.0);
Circle c2 = new Circle(5.0);
System.out.println("c1:(" + c1.getO().getX() + "," + c1.getO().getY()
+ ")," + c1.getRadius());
System.out.println("c2:(" + c2.getO().getX() + "," + c2.getO().getY()
+ ")," + c2.getRadius());
System.out.println("c1 area = " + c1.area());
System.out.println("c2 area = " + c2.area());
c1.setO(5,6);
c2.setRadius(9.0);
System.out.println("c1:(" + c1.getO().getX() + "," + c2.getO().getY()
+ ")," + c1.getRadius());
System.out.println("c2:(" + c2.getO().getX() + "," + c2.getO().getY()
+ ")," + c2.getRadius());
System.out.println("c1 area = " + c1.area());
System.out.println("c2 area = " + c2.area());

Point p1 = new Point(5.2, 6.3);
System.out.println(c1.contains(p1));
System.out.println(c1.contains(new Point(10.0, 9.0)));
}
}
结果为c1:(1.0,2.0),2.0
c2:(0.0,0.0),5.0
c1 area = 12.56
c2 area = 78.5
c1:(5.0,0.0),2.0//此行的预期结果为c1:(5.0,6.0),2.0,不知错出在哪里，哪位高手帮我解答
c2:(0.0,0.0),9.0
c1 area = 12.56
c2 area = 254.34
true
false


[解决办法]
楼主你的代码写错了吧，System.out.println("c1:(" + c1.getO().getX() + "," + c2.getO().getY()
+ ")," + c1.getRadius());
第二个应该是c1.get吧，你写的是c2
[解决办法]
楼主，你自己敲错了一行代码，大约在90-100行左右
也就是你很诧异的那个输出结果的那个println一行

Java code

System.out.println("c1:(" + c1.getO().getX() + "," + c2.getO().getY()                + ")," + c1.getRadius());
