1. Declare an array to save 4 Dog objects. The Dog class is provided below. Look into the Dog class and find what attributes are needed for a dog object. Then initialize five dogs with the following information:
Lily, 5 years old
Jacob, 2 years old
Sugar, 8 years old
Bush, 3 years old
2. Print out every dog using a for loop (use either regular for loop or for-each loop, your choice). But you may find when you print out, the name and age are not displayed. Why?
3. Fix this problem by implementing the toString method in the Dog class.
Dog Class:
public class Dog { private String name; private int age;
public Dog(String name, int age) { this.name = name; this.age = age; } public void setName(String name) { this.name = name; }
}
This is the question I am stuck on -
A. Create a CollegeCourse class. The class contains fields for the course ID (for example, CIS 210), credit hours (for example, 3), and a letter grade (for example, A). Include get and set methods for each field. Create a Student class containing an ID number and an array of five CollegeCourse objects.
Create a get and set method for the Student ID number. Also create a get method that returns one of the Student’s CollegeCourses; the method takes an integer argument and returns the CollegeCourse in that position (0 through 4). Next, create a set method that sets the value of one of the Student’s CollegeCourse objects; the method takes two arguments—a CollegeCourse and an integer representing the CollegeCourse’s position (0 through 4).
B. Write an application that prompts a professor to enter grades for five different courses each for 10 students. Prompt the professor to enter data for one student at a time, including student ID and course data for…

For example: I need to creat a class including the name, description and date and create 7 instances and store them in an array and them print them out.arrow_forwardCreate a new class in the practicum1 package named ArrayUtilities. Write a method in the class that meets the following requirements: - It should be named "arrayToString" - It should declare a parameter for an int array. - It should return a String in the same format as the example above, e.g. "[1, 2, 3]". If the array is length 0, you should return the string "[]". - It should NOT use the Arrays.toString() method - you should create and return the string yourself. - You may receive a warning from IntelliJ about using string concatenation. You may ignore it. Write a main method to test your method by calling it with one or more small arrays and printing the string(s). Example output: [] [1, 2, 3] [2, 3, 5, 7, 11, 13]arrow_forwardMissing codearrow_forward

Please note that since both methods get user input, create a Scanner attribute to use in both. menu method This method does not have any parameters and does not return a value. It should: Get the account number from the user. This corresponds to the index of the items in the ArrayList. Since there are 3 elements in your ArrayList, you are going to ask them for a number between 1 and 3, but keep in mind that the indices of the ArrayList are 0-2, so you'll have to adjust the value you get from the user accordingly.

- Uising the code below. Write a test class called CircleTest that implement below specification: a). The class has an ArrayList that holds objects of type Circle. b). It displays a menu that allows the user to: Enter a Circle (the user only needs to enter the radius). Print all Circles (print the toString for each Circle in the ArrayList). Quit. c). If the user selects option 1, allow the user to input the radius of a circle. Place the circle in the ArrayList in order. You can do this by using loops and the CompareTo method. Do not use methods of ArrayList for this part. Use the compareTo method to insert elements into the array. For example addAt. d) To add a circle Cases: The ArrayList is empty The new circle is less than the first circle, add it at the beginning.
