[Editor's Note]
Are you just a programming beginner? And I have already attracted to the charm of Java language for a long time? Are you intensely like entering the Java world, but feels no way?
Unlike a lot of articles, whenever you encounter such an initiator encountered a problem that is difficult, always introduce a book (these books are usually the "Bible" in the industry to bring these poor children. They have been ignored from the door of the programming of the temple that has just entered ...
The author of this article is another way. From the Java Development Kit (JDK), the author has been installed, and it has always been debugging a model of a classic example helloWorld writing and debugging. Step by step, I will give up the identity of "Java program design master". I personally extend myself for writing procedures and eating, bringing an initiator into the temple of Java programming.
However, if you are really a full-time beginner, I have been very helpful in this article, please don't be comfortable, or take the big head recommended by "prawns" and try to take some days. . The temple of the program is magnificent, there are many rooms, there is a throne in the middle, Java is no exception, whenever you finish a big head, and have a lot of cultivation (writing procedures), you can enter the next room This may take many years, but don't be afraid, no matter which room you are, you have your value. When you have finished all books, you will go to the final room, and after a few years of cultivation, you finally take the throne in the temple.
Is this terrible? No, you ask "Master", so no one is sitting on this throne, but some people have come to the front of the house. Despite your efforts!
