Question

So I'd like to copy a variable in Java without them sharing the same dataset. The variable is an array called ChunkSection[] tsec and I'd like to copy it to ChunkSection[] sec but without the two having any sort of relationship. I've tried .clone() but it didn't work.

ChunkSection[] sec = null;
tsec = fromChunk.i().clone();
for (ChunkSection s : tsec) {
    ArrayList<ChunkSection> chs = new ArrayList<>();
    chs.add(s);
    sec = (ChunkSection[]) chs.toArray();               <-----
}

The code above generates a ClassCastException on the line that arrow points to.

Use Arrays.copyOf to make a copy of an array.

ChunkSection [] sec = Arrays.copyOf(tsec, tsec.length);
