Line breakpoint問題，第一次遇到
? ? public void testForeach(){
? ? System.out.println("有如下課程可選:(通過for each方法)");
? ? for(Object obj:coursesToSelect){ ?//這行提示Line breakpoint:ListTest [line: 82] - testForeach()
? ? Course cr = (Course)obj;
? ? System.out.println("課程:"+cr.getId()+":"+cr.getName());
Line breakpoint:ListTest [line: 82] - testForeach()這個是什么意思？求詳細(xì)解答最好帶上例子。

邏輯錯誤！你循環(huán)重復(fù)定義cr對象！能不錯嗎？
