Java learning ------ author Cai Xuejun January 05, 2005 Java learning ------ author Cai Xuezhen is currently Java can be said to be the most popular language of the industry and academic circles, many readers are very eager I want to learn Java. Unless you can download your professional skills to your mind like a movie "Wheel" (Matrix) (just a few seconds of downloading information), you will immediately have a pilot's skills), or the martial arts novels in the martial arts novels The way, otherwise it takes a bitter study for a while. It takes time, not tightening, I am afraid that the method is wrong, and it is half a time. I think that learning Java includes the following categories: * Principles of Java * Learn Java Language * Object-oriented thinking * API * The usage of development tools will be described in detail below. Learning Java's principles to understand the principles of Java, it is possible to truly understand everything in Java, learn anything, as long as the principle can master the principle, it will be more smooth. I have found that many people have used Java for over the years, but even Java's most basic characteristics are unclear. In general, students graduated from the information system, the speed of information on information, will be faster than other department, because four years of education laid the foundation of learning new things, this is also the value of the information course The location. Unless you have received enough basic training, you will need to refer to the knowledge of this information department in the process of learning or using Java. I suggest that you can read the book of the information system textbook in your leisure time. This is the way of cure, and the special medicine that is not allowed, must be patient. Learning Java language learning Java language is simple, after all, Java language only contains more than 50 keywords (Keyword) and dozens of operators, plus Java syntax (Syntax) is also very simple, so the average person can be very Learn the Java language soon. It is dangerous that many people think that they have fully controlled Java language, but in fact, for internal operational mechanisms still can't master it, these blind spots will sometimes make you unable to control Java languages. Overcoming these blind spots is to see "The Java Language Specification, 2nd Ed." (Without Chinese version) to completely understand the Java program language, and see "Inside the Java Virtual Machine, 2nd Ed." (Chinese version, but translation Get @ #% $) to thoroughly master the way the Java virtual machine works. The learning object-oriented thinking learns the language, does not mean that you can design a good object-oriented system architecture. Experts who want to be object-oriented, often need: * Take more related books, especially Design Pattern and refactoring books. * Dachase, such as Java API's Design and Implementation * Over-write program Learn API learning Java language, you need to learn some API to write a useful program. Java's API is very much, you must plan a learning path, which will not be lost in the vast API sea. The essential API includes: IO, New IO, Collection Framework, Network, RMI, JAXP ..., etc.
