你应该说的是对象的类型是否能改变吧?

算了,这个问题我没想通,我自己想了一下,实例化以后,对象就属于一个类型了,有一天一个人问我String能否改变,值当然可以改变,但我就没有搞清楚他问的是什么能否改变!

String is a special class. String is immutable, if you change the value, JVM creates a new object instance and old string object will be discarded.

Suggest you to study and take SCJP exam, which covers most of java fundamentals.

敝人始终觉得 take the SCJP exam 是花枉钱,
因为付款的考试非需要就不考,
但依循考试的范围学习和做做实习题,也是挺好的Smile
