Java Taskbook Level 9.3

Ask the user for two integers. Create a two-dimensional array whose size is taken from the numbers the user entered. Fill the array with random integers.

The following array is given:

String[] arr = ["123", "456", "789"];

Transform this array into the following:

byte[] arr = {
	{1, 2, 3},
	{4, 5, 6},
	{7, 8, 9}
};

Given some URL:

String url = "http://test.com/dir1/dir2/dir3/page.html";

Get the protocol from it:

"http"

Given a two-dimensional array:

int[][] arr = {
	{1, 5},
	{2, 6},
	{3, 7},
	{4, 8}
};

Split its elements into two arrays:

int[] {1, 2, 3, 4}
int[] {5, 6, 7, 8}
