State machine programming ideas (2): Delete Code comments (currently C/C ++ and Java are supported), programming ideas javaPreface
Sometimes we need to delete comments to keep the information confidential or simply read the code.
I have considered regular expressions before, but it is quite troublesome to implement them. The state machine can classify multiple si
1.1 What is Jocky?We know that Java is a cross-platform programming language whose source code (. java files) is compiled into platform-independent bytecode (. class files) and then dynamically linked at run time. In this way, the compiled class file will contain a signed table, which makes it easy to decompile the Java

For example, to count the workload of a Java programmer writing code in one day (for example, the number of lines of valid code, the number of blank lines, and the number of lines of comments), this tool may serve as a reference.

First of all, a lot of people say, don't look at the source code in the JDK is not called learning java. Obviously that's for sure. For example: a real chef needs to choose and process the ingredients. To the final cooking, plate forming, and even finally to the user to introduce a whole set of processes such as food to go down. In fact, a lot of cooks just do a small part of it, so they can only be called

Java heap is used to store object instances. Therefore, if we constantly create objects and ensure that there is a reachable path between GC Root and the created objects, the objects will not be garbage collected, w

Idea: It mainly simulates the movements of snakes. You only need to perform operations on the snake head, and then copy the first position of the previous State to the second part of the current snake body, copy the second part of the previous snake to the third part of the current snake ...... and so on, to simulate the snake movement.

There are usually two ways to develop Android applications: ndk and eclipse, or add them directly in the android SDK. This section describes how to add an application in the android SDK environment. It involves JNI and Java calls to JNI. The JNI code file is C ++.
The first step is to establish the JNI-Layer Code. Note that the JNI

Variables in Java are broadly divided into two broad categories: member variables and local variables.
member variables:
Variables defined within the class body are called member variables;
If the member variable has a static keyword decoration, the member variable is calledStat

Designing a program that is easy to maintain is one of the most difficult challenges for programmers, partly because the program is not usually maintained by programmer
First of all, many people say, do not look at the JDK source code is not called to learn java. Obviously that's for sure. To make an analogy: the real chef needs to go down from the selection of ingredients, processing, to the final cooking, plate forming, and even to the end of the process to introduce the user to the edible method. In fact, many cooks just do a small part of it, so at most can only be cal
Java programmers rarely notice the results of a program's compilation. In fact, the Java byte Code provides us with very valuable information. In particular, when debugging troubleshooting Java performance Issues, the results of the compilation allow us to understand more deeply how to improve the efficiency of program
