To JAVA beginners + how to learn JAVA

To JAVA beginners + how to learn JAVA-general Linux technology-Linux programming and kernel information, the following is a detailed description. 1. Learning a language cannot be blind. It is necessary to clarify the objectives and methods properly.

It is a good thing to see that many people want to learn JAVA, but it is too blind. At least you have to have a reference book to get started. Although it is so powerful, how can JAVA be easy, but you won't install JDK immediately, right? A good reference book can help you get twice the result with half the effort. I have forgotten the title of SUN's JAVA base, white skin, and title.

2. Do not blindly ask questions.

It is good to ask questions if you don't understand them, but it is very bad to ask questions if you encounter any problems without thinking or trying hard. This means you are not motivated! The learning process is to constantly solve problems. The key to solving problems is to explore and solve them by yourself, rather than relying on others !! For example, if you have asked a question about HelloWorld, I would like to explain it in every reference book. Even if you don't have one, you can get a lot of answers by Google. Remember, if you have a problem, you can find a solution first. You can make more progress only by constantly solving the problem yourself. Also, please learn how to ask questions, and strive to be concise and clear in the jar, no one has so much time to understand your problem, do not post the name of a question similar to "100,000 urgent", "Master invited in". Please use the simplest words to describe your question as the title of the post.

3. In terms of tools, it is not best that you only like them.

Many people use JB when getting started. I think this is not good. Starting with the simplest notepad, you can truly understand the composition of JAVA programs. JB automatically generates too much code and does a lot of things you don't know. In addition, Eclipse is also good.

4. Authentication Theory

Many people blindly go to the test, and then they also like to ask whether the test is used. Authentication is not an aim. It is just a means to learn how much knowledge you can use in practice.

5. Blind greed

Now, we can't say that we are not talking about J2EE. We should not start from the beginning to become greedy and greedy. from the ground up, the J2EE system is not that simple, not just JSP, in the minds of many people, it seems that JSP is not far from J2EE.
