How to copy a row from a 2d array to another

Question

Hi I have a large 2D array ( sample[1000][10] ). I was wondering, how can I copy over the last row (1000) into a temp 2d array ( temp[1][10] )?

EDIT: I have tried the following but I was wondering if there is a much quicker code:

for (int i = 0; i < 10; i++){
temp[0][i] = sample[sample.length - 1][i];
}

Answer 1

使用System.arraycopy ：

System.arraycopy(sample[999], 0, temp[0], 0, 10);
