CompSci 6- Review - Feb. 16, 2010

Main Topics Covered

• Assigned Reading on the calendar
• data types: int, double, boolean
• String class - member functions
  indexOf, length, substring, concatenation, toCharArray, charAt
  collections for loop accessing characters from a string
• Conditional (if), Loops (for, while), Collections for loop
• Class - parts
  Fill in parts of a new class
• arrays
• ArrayList - create, add element to, access element, change element
  add, set, size, get
• Reading from a file, Scanner class
  next, nextLine, nextInt, nextDouble, hasNext
• Graphics - drawing a circle with a pen, Pixmap
• Generate Random numbers

Many of these topics are in the APTs and assignments you did. Study those too!

Logistics

• Just need pen or pencil
• Closed book, closed notes, closed neighbor
• No electronic devices (no cellphones, calculates, computers, etc.)
• No paper - exam will have lots of white space
• will provide Java classes that you may need for the exam (similar to old tests) such as String, ArrayList, Scanner, File

How to Study

• Review classwork, APTs, lecture notes, assignments
  practice writing code on paper
• Old tests - see "Old Tests" link on CompSci 6 Web page under Resources. NOTE we have not covered loop invariants and inheritance (when one Class extends another Class) which may appear on some tests1.
  Today we will go over the solutions for old tests
