 Software life cycle › A sequence of steps in software engineering to develop the specified software  Software improvement models › Various models to help develop software  Object Oriented Programming › Used to build classes and objects and to define the relationship between objects

 The Scanner class is used to read in user input  It has several methods that allow users to manipulate the input › The Split method of the Scanner class allows users to divide the input into chunks with the use of a delimiter › String x = “Jessa/Schwarting/Member”; String[] y = x.split(“/”);

 Wrapper classes are used to convert primitive data types into objects, and to convert objects into primitive data types › Integer.convertToInt(x) › Double.convertToDouble(y) › Etc.

 Inheritance allows users to create parent and child classes, where the parent classes contain variables and methods that the children classes can use. › Parent classes are abstract and can contain abstract methods  Polymorphism allows objects to take on different forms › Generally used when a parent class is used to refer to a child class › Example: Customer x = new NonMemberCustomer();

 Exceptions are errors that occur while a program is running. › Ex: FileNotFound › Users can define their own  I/O Streams › Used to read in files  Number/Decimal Format › Used to format numbers Tutor tip: Find the code for these concepts in your notes and write them down on your crib sheets!

 Nested Classes have two types – static and non-static. › Non-static nested classes (inner classes) have access to whatever is in the enclosing class, private or not › Static nested classes do not.
