3-1 Generics
The most commonly used type parameter names are:
E - Element (used extensively by the Java Collections Framework)
K - Key
N - Number
T - Type
ArrayList

JP 3-4: Sorting and Searching
Bubble Sort (two at a time)
Selection Sort (do comparisons to select the lowest number in unsorted sublist and swap it into the end of the sorted sublist)
Insertion (get the next number and do comparisons to see where it should be inserted into sorted sublist / beginning to end)
Merge (divide and conquer)
Searching

Production Project
Create a class with standard getters and setters
Like a Person class with a field for firstName
Create a TableView in fxml with same number of columns as fields you would like to display.
Like <TableColumn fx:id="firstNameCol" text="First Name" />
Create an ObservableList of the class type in the Controller
Like ObservableList<Person> people = FXCollections.observableArrayList();
Do setCellValueFactory on each column with the field name
Like firstNameCol.setCellValueFactory(new PropertyValueFactory("firstName"));
Note that the first word must match the id from fxml and the last word must match the field name
Set the items of the table to the list
Like tableView.setItems(people);
When you add to the ObservableList the new data will automatically show up in the table
Like people.add(new Person("Damien"));
Last week you wrote code to utilize the following functional interface with a class that implements the interface.
This week, write code to utilize the functional interface with an anonymous class:
interface MyInterface {
public void printIt(String text);
}
MyInterface mi1 = new MyInterface() {
public void printIt(String text){
System.out.println(text);
}
};
mi1.printIt("Anonymous way");
