To understand the shape of a 2D array, consider rows and columns.array([[1, 2], [3, 4]])has a2, 2shape equivalent to 2 rows and 2 columns, whilearray([[10, 20, 30], [40, 50, 60]])has a2, 3shape equivalent to 2 rows and 3 columns. Test this concept using thePython inte...

fastRemove(index); return true; } } return false; } 可以看见进行remove操作时,是通过调用fastRemove()方法进行的实际删除。在fastRemove()方法中,对modCount进行了+1的操作。 private void fastRemove(int index) { modCount++; int numMoved = size - index - 1; if (numMoved > 0) System.arraycopy(...
