1. Write a method starString that takes an integer as its input and returns a string of asterisks whose length is that integer:

starString(5) returns "*****"
starString(3) returns "***"
starString(0) returns ""

2. Write a method drawSquare that takes an int called n as its only input. It does not return anything, but it prints out n lines of n asterisks:

*****
*****
*****
*****
*****

3. Change this loop so it prints ABCDEFGHIJKLMNOPQRSTUVWXYZ with one character being printed each time through the loop.

HINT: Google a Unicode table so you can get the right values and cast the numbers as (char)

for (int i = 0; i < 26; i++) {
	System.out.print(i+1);
}

4. The procedure cross takes an int as its input and prints a cross made out of octothorpes.

Example:

cross(2) -->
  ##
  ##
######
######
  ##
  ##

cross(5) -->
     #####
