Given an array and a value, remove all instances of that > value in place and return the new length. Do not allocate extra space for another array, you must do this in place with constant memory. The order of e

这里再通过System.arraycopy对数组再一次进行拷贝。与Arrays.copyOf不同的是,System.arraycopy只是把index位置及其后面的元素,拷贝到数组的index+1及其后面的位置中,也就是把index及其后面的元素全部后移一位。 最后,把新的元素放到数组的index位置。 public static void arraycopy(Object src, int srcPos, Object ...
