1. Using this Online IDE, create three (3) linked lists named songs, artists, and playlist. You may refer to the sample codes in this module. 
2. Add five (5) song titles to the first linked list then add the five (5) singers/bands of those songs to the second linked list.
3. Combine the first two (2) linked lists and add each combination to the third linked list, which is playlist.
4. Display the content of the three (3) linked lists in separate lines. See sample output below.

Instructions

1. Create a variable that accepts a positive integer.
2. Create an empty array. Then, using loops, add random integer values into the array one by one. The number of values to be stored is dependent on the inputted positive integer given in the first instruction.
3. Print out the largest integer among all the elements in the array, by any means necessary.

Input

The first line contains the size of the array/list.

The next lines contains an integer on each.

Implementation of Stack ADT Operations using Array

Encode the given source code and provide the needed statements which will complete the program.

1. Take note of the following:

• push() is a method that will insert an element at the top of the stack

• pop () is a method that will delete the top of the stack

• peek() is a method that will return the top of the stack

2. Include the following push operations in your code, specifically in the main method:

• push(10)

• push(23)

• push(4)

• push(36)

• push(12)

After compiling and running your code, it is expected that the sample output below will display in your screen.

My Stack Operations

1. Size of stack after push operations: 5

2. Top of the Stack: 12

3. Pop elements from stack : 12 36 4 23 10

4. Size of stack after pop operations : 0

Develop a Java GUI application that will display the petrol cost per litre for three different cities with a time span of three years. Q.1.1 On the form create a list box, to allow a user to select between three different cities. Also create a combo box for the user to select the year. Finally add a submit button. Once the user has selected a city, year and clicked the submit button display the petrol price per litre for that year. Use the following table for the city and yearly petrol prices per litre:

Build a class Department having id (int), address (String) and projects (array list of projects) and workers (array list of workers) a. Provide parameterized constructor Department (String address) which initialized id randomly and array lists as empty array lists. Provide in department class void addProjectWork(int pid, int wide, int hours)

This will add the hours to the worker of the given project. For this you will need to call the appropriate method of the project class i.e addMemberHours which adds the hours for the specified member as well as add to duration of the project

Build a class Project with id(int) , desc (String), duration (int) , budget (double) and members (ArrayList of Workers). a. Provide a parameterized constructor Project (int id, String desc, double budget). The member array will be initialized as empty array and the initial duration of the project will be 0 b. Provide setters for description and budget and getters for all except members list. Provide a method getTotalCost() that calculates the total cost of the project by summing the budget and the salary of each member of the project. The salary of each m ember can be found by calculating an appropriate method of the Worker class.
