How to use processing code written in JAVA.

[system]

I want to use for processing classes code written in JAVA.

also, I want to use these codes for “Unity for Android” and “Unity for iOS”.

Are there any good way?

So if you have code written in java, and you want to have it work in Unity, my recommendation is to retype it in C#. C# is very similar to normal java, so very few changes will need to be made.

example:

This method creates a 2-d array of integers in java, then returns their sum

public int testMethod()
{
    int[][] numbers = new int[4][2];
    for( int X = 0; X < numbers.length; X++)
        for(int Y = 0; Y < numbers[X].length; Y++)
            numbers[X][Y] = X + Y;

    int output = 0;
    for ( int c : numbers)
    {    output += c;    }
    return output;
}

And this code does the same thing in Unity’s C#

public int testMethod()
{
    int[,] numbers = new int[4, 2];
    for( int X = 0; X < numbers.GetLength(0); X++)
        for(int Y = 0; Y < numbers.GetLength(1); Y++)
            numbers[X, Y] = X + Y;

    int output = 0;
    foreach ( int c in numbers)
    {    output += c;    }
    return output;
}

As you can see, they are barely different. You might even be able to just copy the file, change the extension to C#, and then only fixing a small handful compile errors.

If you cross-type into C#, compiling it for iOS and Android is as simple as changing a few checks on the build settings.
