Generics are a facility of generic programming that was added to Java as part of _____

They allow a type or method to operate on objects of various _____

Generics also provides _____-_____ type saftey

Generics

The Motivation

No matter how careful one is at programming, _____ will always exist

Generics

The Motivation

______-______ bugs tell you immediately that something wrong

Generics

The Motivation

______ bugs are much more problematic as they don't always surface _____. When they do surface, it might be at a time that is far removed from where the bug originated

Generics

The Motivation

Generics add _____ to your code by making more of your bugs detectable at _____-_____

Generics

The Motivation

Error Catching

The main motivation is to generate _____-_____ errors rather than _____ errors

Generics

The Motivation

Replacement for Method Overloading

Overloaded methods are often used to perform similar operations on different types of _____

Generics

The Motivation

What is an overloaded method?

Generics

The Motivation

e.g. 2 overloaded methods could be replaced with one method that accepts a non-specific _____

Generics

The Motivation

An example of how to replace 2 overloaded methods with one generic method

Generics

Implementation and Compile-Time Translation

Based on the types of the arguments passed to the _____ _____,the compiler handles each method call appropriately

Generics

Implementation and Compile-Time Translation

Create a generic method called printMe()

Generics

Implementation and Compile-Time Translation

The <T> marks the method as being _____ and specifies the name of the <T> parameter that will be used in the definition

Generics

The Motivation

It will only serve as a replacement for overloaded methods that perform the exact same _____

Generics

When the compiler translates a generic method into Java bytecodes, it removes the type parameter and replaces with actual types. This process is known as _____

Type parameters used in a method's parameter list

The type-parameter names throughout the method declaration must match those declared in the _____-_____ section

Generics

Declaring more than 1 type parameter

Create a method that takes two type parameters:

Generics

Methods that use a parameter as the Return Type

Can a relational operator be used with return types?

Generics

Methods that use a parameter as the Return Type

It is possible to compare 2 objects of the same class if that class implements the generic interface _____

Generics

Methods that use a parameter as the Return Type

Example of Comparable

Generic Classes

Creating a String variable at the top of the class (e.g. Private String Name;) means that it can only take a _____ as its content

Generic Classes

public class GenericBox <T>{

Generically defining a class (as above) enables a lot more flexibility and also includes _____-_____ saftey

Generic Classes

Compile-Time Safety

At compile time, the compiler ensures the _____ safety of your code and uses erasure techniques to enable a more usable system.
