learn java hard way

In school, you start to touch Java, and when you learn the basics of grammar. After graduation, because did not find the internship work and did not engage in Java development, slowly to the Java lost. Several colleagues from the school, some entered the project implementation industry, did the project manager. Some co

Because the work needs, I want to learn C #, in fact, I feel good, I like to learn more language, because this is very helpful to my future development, after all, the technology is not pressure, the following is my study today summarizes C # basic syntax:I have learned C, but also Java programmers, so it is difficult for me to

74% of people think it's not hard.Some people have done statistics and asked more than 500 Java developers who are already working, "is it difficult to learn Java?" "There are 74% of people who think it's not difficult to say that hard to learn is only 26%, then these 74% ar

Unconsciously has been working for more than a year, in this more than a year, learning a lot of knowledge.

ideal is to become an architect, to become a monthly salary of 30,000 Daniel, for his dream, he often saved his knowledge of the technology as a "system architecture diagram" Let Lao Zhang to appreciate. Lao Zhang told him that the structure of the hot technology is not practical work, the architect to choose the right technology according to the needs. Xiao Li thinks that the architect does not have to write code, so for writing code he is to carry out the task of the mentality, in order to pu

: (How to learn Java?) ) Maple Leaf Country Wanderer 2001-07-04 12:37:58 I can combine my experience to say to you roughly, hope to help you, less take detours. Learning Java In fact should rise to learn how to design this realm, in fact, learning program design is to accept a programming idea. The programming ideas of

First, serialization and deserializationThe process of converting an object to a sequence of bytes is called serialization of an object .　　The process of reverting a sequence of bytes to an object is called deserialization of the object .There are two main uses for serialization of objects:1) The object's byte sequence is permanently saved to the hard disk, usually stored in a file;2) A sequence of bytes that transmits an object over the network.The s

Since. NET, programmers are very concerned about a problem is "to learn Java or. net". " I'm struggling too, "it's time to continue with the Java research, or start preparing for the training." NET's knowledge ". Of course, it's best to be able to do both, but everyone's time is limited and it's not easy to take care of both. Put on. NET, the time spent in

Avenue to Jane, so solid useful methods, in fact, are very simple, difficult in the implementation of the process. Today we are going to introduce you to the 7 seemingly very simple ways to learn java.Why learn Java?Java is currently the most popular programming language, mainstream company framework is basically insep

Do not come up to school struts/webwork/spring/hibernate/ibatis and so on the framework, first understand the following techniques, for the learning framework is very important. The first is the reflection mechanism and introspection mechanism of Java. Most frameworks use both mechanisms, because they all implement the recognition and loading of classes automatically through a configuration file, so you must use reflection and introspection. In parti

It does not attempt to explain why someone needs to use JMX. If you do not know, you can refer to the resources at the end of this chapter. Section 31.8, "further Resources" In particular, spring's JMX support provides 4 core features: Automatically registers any spring bean as a jmx MBean. Elas

For the learning in Java Training School, learning atmosphere is very important, with a good learning atmosphere, students will be more active learning, learning quality will improve a lot, in the Silicon Valley, there is a strict discipline, is to ensure that there is a good learning atmosphere, But learning atmosphere can not only rely on strict discipline, but rely on the consciousness of everyone, since we have chosen to

the Java language. From this application, we can see that the This keyword represents the name of the object. Once you have mastered this basic principle, learn about some of the next high-level applications, which are the things that come naturally.Here I just take a formal parameter as an example. In fact, if it is a local variable, it is the same reason. As in the above code, name is not a formal parame

called in a method call or hard-coded way in the program, and AOP dynamic agents can be a good solution to this problem. about the AOP The implementation of dynamic agent is commonly used JDK The reflection also has CGLib , the difference is that the former cannot be a class without an interface and CGlib Yes, we will not say more, because this article is mainly to apply the reflection in the previous thre

Rolemodel.com is a website with the original code and some basic design documents. Another source can go to www.umlchina.com is a good documentation base. From the Hotdraw I learned what the framework is and how to construct it in a rolemodel way so that I can apply it to other places. By the way, this example you will never feel small, only feel big, and he is still the real commercial framework. 7. You

cache, distributed computing all understand, in fact, any one is just floating on the surface. At that time, the interviewer casually asked, he gave you see through.It is important to remember that as a program ape, there may be a lot of technology in contact on weekdays, but to make a technology your advantage, it must be your understanding of this technology is stronger than the vast majority of talent. So at this stage, you can not simply learn th

see the source code in the JDK to improve their programming ability, and so on is the natural thing. Do not write a few lines of code to study what source Ah, mechanism ah, efficiency ah, in fact, is out of the way. In other words, it's a rip.Hope that the above wordy so much, can help you and the same confused little friends. If you have any questions, you can talk to me privately. Java Learning Communica
