Lecture Outline

• Generics allow us to use a "wildcard" data type, which can be any data type (Integer, String, Student, etc). Generic data types are indicated by E OR T in angle brackets. Generics are very useful when we might not know what data type we will be working with ahead of time
• Switch/case is a java construct very similar to if/else.
• Wrapper classes are a way to represent a primitive data type as a Java object
• We can write unit tests to create automated tests for our Java code using JUnit
• Ideally, we want 100% code coverage when we test our programs, but it often times is not feasable
