Remember from Pascal to C when the matrix67 great God wrote the C language Crash Handbook. Although the content is very basic (including things that deal with NOIP: basic statements, data types, operators, and so on, excluding object-oriented parts), it is ideal for people who have mastered a programming language to get started with a new language quickly. The sense of this crash handbook is that it allows the reader to quickly get started with a strange programming language, and other things can continue to learn in practice.
Winter vacation to do a little project, feel that Java may be more concise. However, there is no similar Java crash Manual (most of the market is to the large number of agricultural), so I intend to make a self-made, but also as a Java beginner notes.
Modeled after the M67 is divided into the following units:
1. Basic data types, input and output, functions (methods)
2. Conditions, loops, statements
3. Simple class, String
4. File operation
