Monday (5/3/10)

Warmup:

  1. Create a new file named Warmup_5_3_10.java
  2. Prompt the user for an integer and store it in a variable n
  3. Create a boolean variable named isPrime that starts with true
  4. Write a for loop that starts at 2 and goes up to n
    1. Check if n can be evenly divided by the counter variable (Hint: n % x == 0)
      • If n divides the counter variable, then change isPrime to false
  5. Outside after the loop, check if isPrime is true
    • Print out a message that says that "the number n is prime"
  6. ...otherwise, print out a message that says it is not

Agenda:

  • Introduction to classes
  • Look at Media:Circle.java
  • Create your own Rectangle class and put it into a file named Rectangle.java
  • Test out your Rectangle class by creating another filed named RectangleMain.java
  • Creature Combat Game

Be sure you have demoed or can demo the following:
