AP Computer Science

Monday (11/16/15)

Warmup:

1. Go to the Java String documentation
2. Practice reading documentation by finding method(s) that would help you accomplish the following:
   1. What if you wanted to grab a single character of the String from a particular location?
      1. What is the name of the method? Is it overloaded?
      2. What are the required input parameters to use the method?
      3. What is the return type of the method?
   2. What if you wanted to remove any extraneous spaces or tabs (whitespace) around a String?
      1. What is the name of the method? Is it overloaded?
      2. What are the required input parameters to use the method?
      3. What is the return type of the method?
   3. If you were given a large String and all you wanted to do was isolate the very last word. How would you find the location of the beginning of the last word? (Hint: words are separated by spaces)
      1. What is the name of the method? Is it overloaded?
      2. What are the required input parameters to use the method?
      3. What is the return type of the method?

• Grades in RED are incomplete. You need to go back and complete them

Agenda:

• Demo the following:
  • Guessing Game Assignment
  • Monte Carlo Calculation of Pi
  • Taylor series Pi
  • Taylor series e
• Java For Loops - eIMACS For Loops Chapter

Tuesday (10/6/15)

Warmup:

1. Create a new NetBeans project named SummationWarmup
2. Prompt the user for a variable N (you'll need to create a Scanner to do this)
3. Create a variable named sum and initialize it to 0
4. Write a while loop that sums up the first N natural numbers ( 1 through N ) and stores the results in your sum variable
5. Print out the sum

Agenda:

• Complete Guessing Game Assignment
  • Note, the random number generator code is Python, so you will need to look up how to do it in Java

• Complete Guessing Game Assignment
  • Note, the random number generator code is Python, so you will need to look up how to do it in Java
