  1. CS 120 Day 2 • More Introduction • Computer Science • Software Engineering • Integrated development environments (IDE) • BlueJ • Continue the discussion of the MemoryGame program

  2. Computer Science • Processes • Algorithms • Control Complexity • Abstraction

  3. Software Engineering • Apply Engineering Principles to the development of software. • Definition given by the IEEE • The application of a systematic, disciplined, quantifiable approach to the development, operation, and maintenance of software; that is, the application of engineering to software

  4. Software Engineering • Analysis • Design • Implementation • Testing • Maintenance

  5. Memory Game • Three classes • MemoryGame • MemoryGameWindow • ColorRectangle
