Rookie learns to java-a freshman

At the beginning of 2013 to know Java, because before the C + +, also tested Ncre two C + +, know C + + is a very annoying OO high-level programming language, feel unattainable, and later know that C + + is used to write the underlying code, I feel relieved: at the time of their own level is not worthy of the family at all.

After seeing Java, I found that she is more simple than C + +, and is object-oriented, all aspects of quality conditions are good, a feeling of excitement! But see our Department director given the textbook, suddenly feel she is so difficult to chase, a full 800 pages of "Big bricks" Ah ...

Fortunately later teach US Java teacher did not let us read this textbook, directly to the most easy to understand the entry-level teaching materials to take us to get started, because it is very like Java, and the teacher is not the kind of scripted type of children, so learning is very exciting, but unfortunately did not understand the meaning of Java, The book also did not see much, did not put Java in the heart, so in the bottom of my heart made a wish: hope to be in Java 20 years old before it "chase" hand, proficient in Java.

In an instant more than a year passed, soft test let I have to face her to meet her, found that she has not thought of her for more than a year, the big brick has been in my desk, but never good to see a page, so she can only use déjà vu to describe. Anyway, I did not miss, now come with me to know the beautiful elegant Java bar.

I spent 5 days, the horse soldier Teacher's "J2SE video tutorial" read it again, to tell the truth and not all the understanding of the inside of the things, but horse soldiers teacher's explanation let me think Java is so easy, therefore also have the confidence to complete a year ago to make a wish.

First, I use the mind map to summarize the knowledge points I have seen briefly:

A lot of people may be curious that I have been in front of the Java, and I summed up is J2SE, here to not understand the friend explained: Java is divided into three systems Java SE (J2SE) (JAVA2 Platform standard Edition,java platform standards), Java EE (ee) (Java2 platform,enterprise Edition,java Platform for Enterprise Edition), (J2ME) (Java 2 Platform Micro Edition,java Platform mini version).

As a beginner, of course, you should learn the simplest standard version, easy to get started. As for the details of the knowledge point is no longer one by one to repeat, in the follow-up study will be in Java some of the more difficult to understand the knowledge of the block to discuss in detail, welcome everyone to communicate with me, generous enlighten.

about Java Learning I would like to say a few words, in fact, learning this high-level programming language is not too difficult, in comparison, as long as you master the basic knowledge of the Java language, and can skillfully use JDK_API, plus 100,000 lines of code training, proficient in Java is not a thing!
