Looking for a job to interview, there is an interview with a way to deal with the interview. Some of the following topics come from me and my friend's painful interview experience, including these issues include IBM, E * Trade, Siebel, Motorola, Sun, and other size companies.

Have written on paper, there is a face test you, and there is also a question in the phone, giving you the estimate of the IDE, so you can buy a lottery ticket, maybe it is specified. So if you have finished reading this article, please don't complain that these problems can be solved with IDE. You have to answer these questions in any case, if you have one or two questions in the interview, you will be able to be rejected. Of course, these are the basic questions of Java. Most people who have interviews will not ask you how Hibernate has more advanced, Eclipse's three components, or Command Design Pattern, they are all aged, and the favorite is basics. . Don't underestimate these foundations, my friend is first-class, and the results are planted under the basis of basics, and the high salary is not worthy. It's better to say less nonsense and start the topic. First, talk about the difference between Final, Finally, Finalize. It is most often asked. Second, anonymous inner class (anonymous internal class) can be extends other classes, can IMPLEMENTS INTERFACE (interface)?
