Write a Program in Java programming:
Support you have an ArrayList containing random integers. These integers can be any number, and each integer can appear more than once. For example, [2, 19, 21, 19, 21, 1, 3, 3, 6, 21, .....]
Your job is to write a method called findEvenFrequentNumbers(ArrayList<Integer> list) that returns an ArrayList which has all the numbers appears in even frequency and in increasing order.
e.g.
list = [2, 19, 21, 19, 21, 1, 3, 3, 6, 21], should return [3, 19]
list = [3, 3, 3, 1, 2, 2, 2, 2, 2], should return []
list = [1, 1, 1, 1, 1], should return [1]
Note that you need to provide a class with the main function and also the imports.
We want to write a Java program to encode a name by creating an array of integers.
Write Java method called encodeName that takes a name as a string (without spacing and all lower case) and returns an array of integers of the same size as name whose elements are the number in the alphabet of the corresponding character in name (starting from zero). For example, calling this method with name = “aabed” it should return [0, 0, 1, 4, 3].
Write a printArray method that prints all the elements of an array of integers in one line.
Write a main method that calls encodeName and printArray methods to print the array corresponding to your name.

Write a java program that uses an ArrayList object to store the following set of names in memory:
[Steve, Tim, Lucy, Pat, Angela, Tom]
Now write some more code so that the same ArrayList object is augmented with the name 'Steve' after the name 'Lucy'
After the ArrayList object has been augmented with the new name, display the original and new lists on the console (as shown below), to verify that the new name is positioned correctly in the list.

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 course.java import java.util.ArrayList; // Class representing a studentpublic class Course { private ArrayList<Student> roster; // Collection of Student objects public Course() {…arrow_forwardProvide a different implementation of ChoiceQuestion.

- The implementation of a queue in an array, as given in this chapter, uses the variable count to determine whether the queue is empty or full. You can also use the variable count to return the number of elements in the queue. On the other hand, class linkedQueueType does not use such a variable to keep track of the number of elements in the queue. Redefine the class linkedQueueType by adding the variable count to keep track of the number of elements in the queue. Modify the definitions of the functions addQueue and deleteQueue as necessary. Add the function queueCount to return the number of elements in the queue. Also, write a program to test various operations of the class you defined.arrow_forwardWrite a program in java that randomly fills in 0s and 1s into an n-by-n matrix, prints the matrix, and finds the rows and columns with the most 1s.
