A brief introduction to "Novice Learning Java" 1:java language __java

At the beginning of 2013 to know Java, because before the C + +, also tested Ncre two C + +, know C + + is a very annoying OO advanced programming language, feel unattainable appearance, later know C + + mostly used to write the underlying code, In the heart to feel relieved: at that time their level is not worthy of others.

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 the heartbeat ah. But see our Department director given the textbook, immediately feel that she is so difficult to chase, a full 800 pages of "Big brick block" Ah ...

Fortunately, we later taught the Java teacher he did not let us read this textbook, directly to get the most easily accessible entry-level textbooks to take us to get started, because we like Java, and the teacher is not that kind of scripted, so the study is very exciting, but unfortunately did not understand the meaning of Java, The book is not how to see, can not put Java in the heart, so in the bottom of my heart made a wish: I hope to be 20 years old in Java before the "chase" hand, proficient in Java.

In the blink of an eye a year passed, soft test let me have to go back to the face of her know her, found herself this more than a year has not how to think of her, the big brick has been in my desk down, but never a good look at a page, so the understanding of her can only be described by déjà vu. Anyway, I did not miss, now come with me to meet the beautiful and elegant Java bar.

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

First of all, I use the mind map to make a simple summary of the knowledge points I have seen:

Many people may be curious that I have been talking about Java, and I summed up is J2SE, here to the friends who do not know: Java is divided into three systems Java SE (J2SE) (JAVA2 Platform Standard Platform Standard Edition), Java EE (Java ee) (Java2 platform,enterprise Edition,java Platform Enterprise Edition), java-based ME (J2ME) (java-based 2 Platform Micro platform miniature).

As a beginner, of course, we should learn the simplest standard version, easy for us to get started.          As for the details of the knowledge point is no longer one by one to repeat, in the subsequent study of Java in some of the more difficult to understand the knowledge block for detailed discussion, welcome everyone to communicate with me, generous enlighten. About Java learning I would like to say a few words, in fact, learning this advanced programming language is not too difficult, in comparison, as long as you are proficient in the Java language Basic grammar knowledge, and can skillfully use JDK_API, plus 100,000 lines of code training, proficient in Java is not a matter.
