In this lesson, students will learn about and use ArrayLists. ArrayLists are similar to arrays, except that they are a mutable list of object references. ArrayLists provide a convenient way to create adjustable arrays. This lesson corresponds with AP Computer Science A topic 7.1.
Students will be able to:
In this lesson, students will explore and use 2D arrays. A 2D array is an array that stores arrays! This lesson corresponds with AP Computer Science A topic 8.1.
Students will be able to:
In this lesson, students will extend their learning on 2D arrays by traversing through them. When attempting to access all elements in a 2D array, we can do so in two different ways. Row-major order traverses the 2D array by accessing each value in a row before moving to the next row and column-major order traverses each column down all rows before moving to the next column. This lesson corresponds with AP Computer Science A topic 8.2.
Students will be able to:
This lesson builds toward the following Enduring Understandings (EUs) and Learning Objectives (LOs). Students should understand that?
EU Con-2 Programmers incorporate iteration and selection into code as a way of providing instructions for the computer to process each of the many possible input values. (LO’s 2.N)
EU Var-2 To manage large amounts of data or complex relationships in data, programmers write code that groups the data together into a single data structure without creating individual variables for each value. (LO’s 2.F, 2.G)
In this lesson, students will learn about superclasses and subclasses. A superclass is a parent class that contains common attributes and behaviors used by subclasses (children). Subclasses can draw upon the existing attributes and behaviors of the superclass without repeating these in the code. This lesson corresponds with AP Computer Science A topic 9.1.
Students will be able to:
In this lesson, students will learn about recursion and recursive methods. A recursive method is a method that calls itself. Recursive methods contain at least one base case, which halts the recursion, and at least one recursive call. This lesson corresponds with AP Computer Science A topic 10.1.
Students will be able to:
This lesson builds toward the following Enduring Understandings (EUs) and Learning Objectives (LOs). Students should understand that?
For this 2 part FRQ, students will need to loop through an array to find a maximum value of an object. They will also need to apply conditional statements in this part.
For part B, students will need to write a method overload that will update values of an object.
This FRQ will require students to write a complete class. Students will also need to add, remove and access elements in an ArrayList and iterate through the list to print results.
