This series of blog for the original blog, designed to learn the use of collation, reproduced please indicate the source, thank you.

As one of the most successful languages, Java has many places to learn, not just the use of language.

The goal of this study is to learn from Javase, to learn the idea of Java, and to learn javase and his usage directly from the code level, in order to learn the Java class Library, Java Development Framework and EE, Java Virtual machine, Javaweb lays a good foundation and strives to make programming an idea, a part of the body.

The purpose of this study is to learn Java's world view and methodology, to conform to the philosophical theory, and to learn the spiral in the process of re-understanding in practice---

For data structures and algorithms, the focus is not on the principle of understanding, and the self-realization of the reserve to GitHub to prepare for a rainy days.

Let's get started now!

Once the JDK is installed, let's take a look at the JDK directory first.

JDK (Java Development Kit)

Bin directory: Contains javajdk executable files, is necessary development tools, such as Java, Javac (Java compiler)

DB directory: Java-developed database Apache Derby, is an open source 100%java developed relational database, with not much.

Include directory: the C language header file supports native code programming with the Java local interface and the Java Virtual Machine interface and is temporarily not available

JRE directory: The JRE is the Java Runtime Environment, the individual temporarily understand the JVM is in this, in short, support Java class run

LIB Directory: The code base to be used by the JRE, property settings, resource files.

Src.zip Compressed directory: archived Java source code.
