Complete the Course class by implementing the printRoster() method, which outputs a list of all students enrolled in a course and also the total number of students in the course.
Given classes:
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. (Hint: toString() returns a String representation of the Student object.)
Ex: If the following students and their GPA values are added to a course:
Henry Cabot with 3.5 GPABrenda Stern with 2.0 GPAJane Flynn with 3.9 GPALynda Robison with 3.2 GPA
then the program output is:
Henry Cabot (GPA: 3.5) Brenda Stern (GPA: 2.0) Jane Flynn (GPA: 3.9) Lynda Robison (GPA: 3.2) Students: 4

4. Say we wanted to get an iterator for an ArrayList and use it to loop over all items and print
them to the console. What would the code look like for this?
5. Write a method signature for a method called foo that takes an array as an argument. The
return type is void.
6. What is the difference between remove and clear in ArrayLists.

- Make sure each program has at least one method in addition to its driver method(main). Or use one driver main method and write method(s) for each of the program. Write a Java program to find the mode of an array of integer numbers. Use a nested loop for implementation. Using Java inbuilt classes and method to effortlessly solve this will attract a zero point.arrow_forwardExplain what an overloaded method is and give an example by writing some Java code.arrow_forwardImplement a complete calculator system in JAVA and GUI. implement add, sub, multiply, divide in your system.

- Iterating over a collection of items is the job of the for construct's looping mechanism. So long as there are things to process, it will keep running forever. So, what do you make of this?arrow_forwardHow we can execute any code even before main method?arrow_forwardCreate, compile, and run a recursive program. Choose one of the labs listed below and program it. More details for the lab can be found in the first PowerPoint for Chapter 9. Make sure your code is recursive. You can think of recursive code this way: If you cut and paste a recursive method into another class, it should still run without problems. In other words, you cannot have any instance variables (class-level variables) that the method depends on. Choice 1 - boolean isPalindrome (String str) that returns true if the input string is a palindrome. Choice 2 - boolean find (string fullStr, string subStr) that tests whether the string subStr is a substring of fullStr Choice 3- int numDigits (int num) to determine the number of digits in the number num Choice 4 - double intPower (double x, int n) to compute x^n, where n is a positive integer and x is a double precision variable Choice 5-void printSubstr (String str) that prints all substrings of the input string.arrow_forward
- Java Netbeansarrow_forwardPlease use java only and public int method. Show the steps with the pictures also. In this assignment, you will implement a class calledArrayAndArrayList. This class includes some interesting methods for working with Arrays and ArrayLists. For example, the ArrayAndArrayList class has a “findMax” method which finds and returns the max number in a given array. For a defined array: int[] array = {1, 3, 5, 7, 9}, calling findMax(array) will return 9. There are 4 methods that need to be implemented in the A rrayAndArrayList class: ● howMany(int[] array, int element) - Counts the number of occurrences of the given element in the given array. ● findMax(int[] array) - Finds the max number in the given array. ● maxArray(int[] array) - Keeps track of every occurrence of the max number in the given array. ● swapZero(int[] array) - Puts all of the zeros in the given array, at the end of the given array. Each method has been defined for you, but without the code. See the javadoc for each…arrow_forwardCan we have two methods in a class with the same name?arrow_forward
