# JavAssembly
**A simple example showing how assembly language can be called from Java using the Java Native Interface (JNI). The native function sums the elements of an array of integers and returns the result as a long.**
# Getting started
#### :heavy_check_mark: Requirements
To compile and run this project, you will need:
- the JDK
- an assembler such as NASM or Yasm
- a compiler such as GCC, Clang or MinGW-w64
The example and build scripts can easily be modified to accommodate other assembler or compiler requirements.
#### :cd: Running the code
Simply use the following commands:
```
git clone https://github.com/PyvesB/javassembly.git
cd JavAssembly
#Linux or macOS
./build nasm
#Windows
build nasm
java JNIArraySum
```
