Write three lines of code, one that creates a Random object, a second that assigns a random 3-digit integer (ie, 100..999) to int x, and a third that assigns a random double in the range 100..999 to double y. 2) (3 Pts) Write a static method dup2D that duplicates and returns a 2D array of int. You may assume there is at least one row and column and that each row of the array is the same length. 3) (3 Pts) Write a static method delFifths that takes a String as a parameter and returns the same string but with every fifth character deleted (ie, delete at index 4, 9, 14, etc). So, "Hello world!" would become "Hell word!". Do not use charAt. Note: in a for-loop you may write 1+-5 instead of 1++ to increment 5 at a time.
