Write assignments to the library, cs101, and track variables (which you defined in the previous three exercises) to create the appropriate ArrayList objects. Write them once using diamond notation and once without diamond notation, specifying the full type.

Right now we have a CourseListType that will hold a static 50 courses. Now we need to make that a little more flexible. To do that we want to change the static array to a dynamic array. So, what do we need to do? Modify CourseListType so that it contains a pointer to a CourseType rather than an array of CourseType. Modify the CourseListType constructor to create a dynamic array allocating space for a specific number of CourseType elements rather than always using 50. (Note: This is still not totally flexible, but is much better than a static limit.) Finally, we need to create a destructor to for CourseListType to deallocate space whenever a declared object goes out of scope.) //courseListType.h file #ifndef COURSELISTTYPE_H_INCLUDED#define COURSELISTTYPE_H_INCLUDED #include <string>#include "courseType.h" class courseTypeList { public:void print() const;void addCourse(std::string);courseTypeList(); private:static const int NUM_COURSES = 50;int courseCount;courseType...

Update it to create a class Student that includes four properties: an id (type Integer), a name (type String), a Major (type String) and a Grade (type Double). Use class Student to create objects (using buttonAdd) that will be read from the TextFields then save it into an ArrayList. Perform the following queries on the ArrayList of Student objects and show the results on the listViewStudents (Hint: add buttons as needed): d) Use lambdas and streams to calculate the total average of all Students grades, then show the result. e) Use lambdas and streams to group Students by major, then show the results. 1.

Add a new method to ArrayTools with filter. Make this method accept a String array. Change all the Strings that are longer than 5 characters to uppercase. Write in Java and use test cases 1 & 2 as a result.

Create a class called Student that models a student at Carleton University. A student's state consists of a name (String), id number (int) and a list of grades (array of double). Your class must have a constructor that has three input parameters (name, id and grade list) and sets the initial state for the object. Include a toString() method that returns a useful string representation of a student object. The string representation should contain the student's name, ID number, and the number of grades they have recorded (so NOT include all the grades). Include a gradesInRange(double lower, double upper) method that returns the number of grades that this student has that are in the range [lower,upper]. That is, the it returns the number of grades that are greater than or equal to lower and less than or equal to upper. Example Usage: double[] grades {81.2, 93.2, 76,2, 84.6, 63.11, 79.8}; Student s new Student("cat", 100123987, grades); s.gradesInRange (80,100); int num_grades_A // assert...

Say we are about to build an ArrayList. Your ArrayList should guarantee that the array capacity is at most four times the number of elements. What would you like to do to maintain such a limit on the capacity? What is the benefit of using iterators? Can you describe your first experience of GUIs? And could you describe what is the advantage of using GUIs over Command-Line Interface (CLI) operations?

Please look at the images for the programming question. I am not sure sure where I should start on this. All coding is done in Java, using IntelliJ Idea.

Hello all! need some help with this assignment. Need the sample output as listed in the image. Thank you!

Execute the following statements over initially empty ArrayList myList one after another (cascade). Explain what was changed after each statement (what did it do?) myList.add("z"); ArrayList content: Your explanation (where this output came from): myList.add(0, "a"); ArrayList content: Your explanation (where this output came from): myList.add("t"); ArrayList content: Your explanation (where this output came from): myList.add(2,"w"); ArrayList content: Your explanation (where this output came from): myList.set(0,"b"); ArrayList content: Your explanation (where this output came from):

Complete the Course class by implementing the courseSize() method, which returns the total number of students in the course. Given classes: Class LabProgram contains the main method for testing the program. Class Course represents a course, which contains an ArrayList of Student objects as a course roster. (Type your code in here.) Class Student represents a classroom student, which has three fields: first name, last name, and GPA. Ex. For the following students: Henry Bendel 3.6 Johnny Min 2.9 the output is: Course size: 2 public class LabProgram { public static void main (String [] args) { Course course = new Course(); // Example students for testing course.addStudent(new Student("Henry", "Bendel", 3.6)); course.addStudent(new Student("Johnny", "Min", 2.9)); System.out.println("Course size: " + course.courseSize()); } } public class Student { private String first; // first name private String last; // last name private...

Exercise #2 Implement an instance method belonging to the IntArrayBag class that takes two input parameters, oldVal and newVal. The method replaces each oldVal element in the array with newVal. Make sure to include the method header.

The WalkingBoard class represents a board with a figure standing on position x,y. Each position also has a value associated with it. Initialise the board in two different ways: either make it size×ばつsize or use the given dimensions and initial values. About the second way: The rows may not be uniform: they may have differing numbers of columns in them. Don’t simply take the argument array: create its copy in the field. All values are set to BASE_TILE_SCORE, or to the given value if that’s bigger. Operations. getPosition: returns the values of x and y in an array. getTile: returns the value of the of the board position. Let this condition be checked by the helper method isValidPosition. If it is an invalid position, throw an IllegalArgumentException. getTiles: returns the values of all the board positions. Don’t let the field contents be accessed from the caller: create and return an exact copy of the structure. getXStep and getYStep: helper methods, they indicate how far (-1,...
