ina, MLAn Date Name Final Exam av Winter 2017 Write a program that defines a Print Job structure as follows: 1) An integer job ld 2) A string user name (maximum 25 characters) 2 3 An integer tray (tray will hold the tray number 1 for 8 by 11 paper, number for 8 by 11 paper, and number 3 for 8 paper) is normal, 150% is 4) An integer for paper size (this will hold a percentage: 100% 1.5 times the size) together, all the 5) A string for whether the pages are to be sorted (all the page 1's page 2's stacked (1, 2, 1, 2, 1, 2, etc.) 6) Acharacter for whether the documents should be stapled (Y or N 7) An integer coded for side (221 to be double sided, taking 2 pages and turning it into 1 page, front and back; 121 means to be printed double sided, from a double sided document: 111 means 1 side only to 1 side only or a normal copy) 8) An integer number of copies 9) An integer status (1 means not printed, 0 means printed) Your program will information from the file jobs.txt. Your program will read in an unknown number of jobs into an array (max of 10). The reading of the files may be done in main0, or you may create a function for this. Your program will utilize four functions: display Menu(): Will print the following menu and ask for the user's option. This function will return the choice to main. You must validate the user's entry with a loop. Zoooo ks Copy Menu Press 1 to print the next job Press 2 to see the jobs in the print queue Press 3 to see the job have finished printing Press 0 to quit Enter choice print Job0: Will print the job from the top of the list. This function wil turn the status from 1 (not printed) to 0 (printed) display)ob(): Will display all the jobs in the list still to be printed. finishedJobs0: will display all the jobs that have been printed.

Explanation / Answer

Below is your code in java:

PrintJob.java

public class PrintJob {
   private int jobId;
   private String userName;
   private int tray;
   private int paperSize;
   private String sortOrStack;
   private char isStapled;
   private int sided;
   private int noOfCopies;
   private int status; // 1 means not printed 0 means printed

   public PrintJob() {
       this.status = 1;
   }

   public int getJobId() {
       return jobId;
   }

   public void setJobId(int jobId) {
       this.jobId = jobId;
   }

   public String getUserName() {
       return userName;
   }

   public void setUserName(String userName) {
       this.userName = userName;
   }

   public int getTray() {
       return tray;
   }

   public void setTray(int tray) {
       this.tray = tray;
   }

   public int getPaperSize() {
       return paperSize;
   }

   public void setPaperSize(int paperSize) {
       this.paperSize = paperSize;
   }

   public String getSortOrStack() {
       return sortOrStack;
   }

   public void setSortOrStack(String sortOrStack) {
       this.sortOrStack = sortOrStack;
   }

   public char getIsStapled() {
       return isStapled;
   }

   public void setIsStapled(char isStapled) {
       this.isStapled = isStapled;
   }

   public int getSided() {
       return sided;
   }

   public void setSided(int sided) {
       this.sided = sided;
   }

   public int getNoOfCopies() {
       return noOfCopies;
   }

   public void setNoOfCopies(int noOfCopies) {
       this.noOfCopies = noOfCopies;
   }

   public int getStatus() {
       return status;
   }

   public void setStatus(int status) {
       this.status = status;
   }

   //function to print line of print job.
   public String toString() {
       String s = this.getJobId() + "       " + this.getUserName() + "       " + this.getTray() + "       "
               + this.getPaperSize() + "       " + this.getSortOrStack() + "       " + this.getIsStapled() + "       "
               + this.getSided() + "       " + this.getNoOfCopies() + "       ";

   return s;
   }
}
