Native Library provides a low-level optimization with productivity for C/C++ application.

• Blazing fast performance, small footprint, low-level access with GAS & C
• Provide rich Java core packages for productivity & maintainability
• Zero memory leak with automatic storage
• Prevents segfaults and null pointer exception

This project is also useful for new developers in practical programming.

Compile your source and link with native library

$ g++ -c -o main.o HelloWorld.cpp
$ g++ -o main main.o -lnative
$ ./main one two three

Output:

We have 4 pairs:
argument 3 is three
argument 2 is two
argument 1 is one
argument 0 is ./main

[{"argument 0": "./main", "argument 1": "one", "argument 2": "two", "argument 3": "three"}]

This library provides Java classes in C++ so its syntax is friendly for both programming languages but we still have some issues :

• Namespace - Package

// Java
System.out.println("Java");

// C++
System::out::println("C++");

• Array

// Java
byte[] byes = {};

// C++
Array<byte> bytes = {};

• Interface

Coming soon

• Runtime

Coming soon

• Garbage Collection

Coming soon

All data types are implemented and ready to use in C++ Application

• char - Java.Lang.Character
• byte - Java.Lang.Byte (equivalent with unsigned char)
• string - Java.Lang.String (equivalent with char*, Java does not have data type string)
• unicode - java.lang.Character (equivalent with wchar_t)
• short - Java.Lang.Short
• int - Java.Lang.Integer
• long - Java.Lang.Long
• float - Java.Lang.Float
• double - Java.Lang.Double
• boolean - Java.Lang.Boolean (equivalent with bool)
• enum - Java.Lang.Enum

All Java packages are in transformation so we can have a general look about road map
