Answer 1

You will need two for-loops; one to print the line, and one to print the characters in a line. The number of the current line can be used to print a certain number of stars.

Use System.out.print("*") to print without adding a new line, at the end of the second loop do a System.out.println()

I'll leave the implementation of the loops as an exercise, here is the syntax: http://docs.oracle.com/javase/tutorial/java/nutsandbolts/for.html
