Improve the method printList to print out the details of all publications ordered on the category of the publications, and then on the title within each category. Note: currently there are only 2 categories, i.e. Book and Journal, but the project may be expended by adding other categories, e.g. Newspaper etc.
Here are my four classes.
Â
public class Database {private ArrayList<Publication> publicationList; // An array list collection of publications
/*** Create a new database*/public Database() {publicationList = new ArrayList<Publication>();}
/*** Add a publication** @param publication The publication to be added*/public void addPublication(Publication publication) {if (publicationList.contains(publication)) {System.out.println("This publication has already been added to the list: " + publication);} else {publicationList.add(publication);}}
/*** Get the total number of publications** @return The total number of publications*/public int getTotal() {return…
Create a version of the previous project that reverses the computation. That is, read a value representing a number of seconds, and then print the equivalent amount of time as a combination of hours, minutes, and seconds. (For example, 9999 seconds is equivalent to 2 hours, 46 minutes, and 39 seconds.)
You are to write a program that allows the user to draw a simple house using 5 mouse clicks.
- The first two clicks will be the opposite corners of the rectangular frame of the house.
- The third click will indicate the center of the top edge of the rectangular door. The door should have a total width that is 1/5 of the width of the house frame. The sides of the door should extend from the corners of the top down to the bottom of the frame.
- The 4th click will indicate the center of a square window. The window is as wide as the door. (A change from the original book program.)
- The last click will indicate the peak of the roof. The edges of the roof will extend from the point at the peak to the corners of the top edge of the house frame. Make the lines of the roof edge green. (Another change from the original book program.)
