為什么調用toString方法輸出的還是地址值
Course cr1=new Course("1", "shujujiegou");
?courseToSelect.add(cr1);
?Course temp=(Course)courseToSelect.get(0);
?System.out.println(temp.toString());
?System.out.println(temp.id+" "+temp.name);

復寫Course類中的toString方法
@Override public?String?toString()?{ ????return?"Course?[id="?+?id?+?",?name="?+?name?+?"]"; }
