关于eclipse：Java toString不起作用

Java toString doesn't work

本问题已经有最佳答案，请猛点这里访问。

我有一个应用程序在eclipse的rectangel count，高度，宽度从点(P1、P2、P3，…，P10)。

印刷的点是这样的：

1	Point@659e0bfd, Point@2a139a55, Point@15db9742, Point@6d06d69c, Point@7852e922, Point@4e25154f, Point@70dea4e, Point@5c647e05, Point@33909752, Point@55f96302

你能告诉我它看起来应该如何样？I don’t get it toString方法的论文。在其余的代码是什么样子的？
