2 Stars and why we use nested loops  Matrix problems (stars)  Other problems involving multiple dimensions  Loops within a process that is in a loop (think Loopy 8 ball.

3 Exam 1 – Part 3 V1 A program that uses no variables. A program that includes the following print statement: System.out.println(“Hello World); A PA1 submission that calculates the average by summing the grades and dividing by 7. A program that fails to instantiate a Scanner object before using its nextLine() method.

4 Exam 1 Part 3 V2 A program that has no print statements (either println, print, or printf). A program that includes the following print statement: System.out.println(“Hello World); A PA1 submission that left aligns all of the output labels. A program that fails to instantiate a DecimalFormat object before using its format() method.

5 Exam 1 Part 3 V3 A program that contains a Scanner declaration but does not import the Scanner. A program that includes the following print statement: System.out.print(“Hello World”); A PA1 submission that calculates the average by summing the grades and dividing by 7. A program that fails to declare the variable, abc, before initializing it.
