Question

Need help with the UML for this code? Thank you.

import java.util.Scanner;
   public class Assignment1Duong1895
   {
       public static void header()
       {
           System.out.println("\tWelcome to St. Joseph's College");
       }
       public static void main(String[] args) {
           Scanner input = new Scanner(System.in);
           int d;
           header();
           System.out.println("Enter number of items to process");
           d = input.nextInt();
  
           String itemNames[] = new String[d];
           double itemPrice[] = new double[d];

           for(int i=0;i<d;i++) {
               System.out.println("----Enter Item "+(i+1)+" details----");
               System.out.print("Enter Item Name:");
               itemNames[i] = input.next();
               System.out.print("Enter Item Price:");
               itemPrice[i] = input.nextDouble();
           }

           System.out.println("Item details in reverse order:");
           System.out.println("Item Name \t Item Price");
           for(int i=d-1;i>=0;i--) {
               System.out.println(itemNames[i]+"\t\t"+itemPrice[i]);
           }
  
//Computing average for item names with Peas
           int total = 0;
           double peas;
           double sum = 0;
           for(int i=0;i<d;i++) {
               if(itemNames[i].equalsIgnoreCase("Peas"))
               {
                   sum = sum + itemPrice[i];
                   total++;
               }
           }
           peas = sum/total;
  
           if(total==0) {
               System.out.println("no average output");
           } else {
               System.out.println("Average price for Peas :"+peas);

Thanks for asking question here.

Please see the UML diagram for your above program.

You can create UML diagram of Java code via eclipse very easily.

Please follow the below process

1. Download ecplise and create Java Project.

2. Write the above code in Java class file.

3. Then, go to the help link in your ecplise and click on new software.

4. enter URL "http://www.objectaid.com/update/current" in work with box and add it.

5. Enter below in popup Box

Name: ObjectAid UML Explorer
URL: http://www.objectaid.com/update/current

6. Then, complete the installation

7. Restart the eclipse

8. Right click on your project . Go to the "New" and find Object Aid UML Diagram folder. Inside that folder select Object Aid Class Diagram and open.

9. Drag the Java class and drow into the opened editor . UML will be created automatically.
