1. Understand for loops.
2. Write a while loop for a simple ATM.
3. Read input and error check.
4. Manage flow of control using boolean values.
5. Prepare for the next programming assigment.

for(int i = 0; i < 5; i++)
    System.out.println(i);

int j = 0;
while (j <= 9) {
    System.out.println(++j);
}

for(int j = 10; j >= 0; j--);
    System.out.print(j + " ");
    // are you sure?

for(int n = 0; n > 0; n++)
    System.out.println(n);

int j = 0;
do {
    System.out.println(j);
    j--;
}
while (j > 0);

1. Create a new class in Eclipse called R6.
   - Check the box to have Eclipse add the main method for you
2. Print the welcome message and beginning of the menu:
   
   Welcome to the CS160 Simple ATM!

3. Add a scanner to read input from the user (the console).
4. Add a variable to keep track of the user's account balance.
5. while the user wants to complete an action:
   • Ask them what they want to do
   • Save the response into a variable
   • Use a boolean variable to know when to stop
6. If the user enters a 0, the program should end, otherwise, prompt again.
7. When the loop is done, print the goodbye message:
   Thanks for using the CS160 Simple ATM, goodbye!
