Question

I’m running into this compiler error due to my extremely large lookup table based on this definition:

//92 X 182 array
private static final double[][] lookUpTable = new double[][]
{
    { numbers....}
};

As i understand it, dividing it up is a solution, but it would be extremely difficult to split this array up accurately. I also believe i could move it out to a file, but i don’t know if i could format it in a way to help me, plus i don’t want file reads every second.
Are there any other suggestions to help me get around this?

Answer 1

Convert your table to a file, embed the file as a resource, read it once in a static initialization block, and store it in a lookUpTable array. It will not be distinguishable from an array initialized through an aggregate, except there would be no 65535 limit. Storing in a static variable will help you avoid “reads every second”.

As far as the format is concerned, you can put each row of the matrix in a separate line of the resource file. Reading and maintaining this file would be simple, because there would be no other mark-up around your numbers.
