Otherwise, no one will like your converter.The first thing you need to do is write a variable name converter. Given a variable name, you must first check whether it is Java or C

C Language: code compiled to get machine code, machine code on the computer directly running, each instruction directly control CPU work.
Other languages: Code compiles the bytecode, and the virtual machine executes the bytecode and converts it to machine code to run on the processor.
Python's syntax is concise, the class library is rich, and if you implement the same functionality, Python may need 10 lines of code, and
1. JNI
JNI is the abbreviation of Java Native Interface. Java Native Interface (JNI) standards have become part of the java platform since Java1.1. It allows Java code to interact with code written in other languages. JNI was initially designed for locally compiled languages, especially

The most annoying thing about the transformation and upgrade of old systems is cross-platform and cross-language. One of my friends recently specialized in. Net from Java-Because. Net CLR has a proven underlying hosting capability similar to the Java Virtual Machine Concept. It also provides good compatibility with desktop applications for Windows.
Recently, my personal projects are also face
Eclipse is an excellent source code editing tool that supports symbol table parsing like source insight. In addition, it also supports lexical analysis, syntax analysis, external symbols, introduction of external header files, SVN, CVS project management, and other functions. It is one of the powerful tools for software development in Linux.
The process of configuring eclipse that supports java is similar to that of

The simplest steps for Java to call C/C ++ code
JNI (Java Native Interface)
Java is a cross-platform language, but sometimes it still needs to be called locallyCode(These codes are usually written by C
Original article: Java calls C (implementing Java local methods in Linux)
1. Declare local methods in the Java class and use the native keyword
Public class mynative {
Public void showparms (string S, int I, Boolean B ){
Showparms0 (S, I, B );
}
Public int hypotenuse (int A, int B ){
Return hypotenuse0 (A, B
The memory allocation of the array in Java is in the heap, must be allocated with new, and C + + inside the stack is allocated (in addition to using the pointer new out of the array), the definition will be automatically assigned.1. Arrays in Java(1) An array is not a collection, it can only hold references to multiple primitive types or objects of the same type.

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 code path has a great relationship with the
After reading this document from the Internet, I felt that it was not very difficult and novel. After all, I had very few projects to develop C language. now I have reprinted this article and added some of my notes.
