Hello,
I've been wondering what the easiest way is to set
the dimension of an array during runtime.
You can't write
byte[][] a = new byte[size][size];
because the compiler will give an error. The only
thing I've been able to think of is
byte[][] a;
a.length = size;
for (int i; i < size; i++) {
a[i].length = size;
}
But it's slower (and less convenient) than
writing
byte[][] a = new byte[9][9];
The syntax might seem a bit misleading, but you can create
multidimentional arrays like this:
int[][] foo = new int[][](5,10);
foo[4][9] = 31337;
this also works for single-dimention arrays (e.g int[] foo = new int[](size);)
