  1. POVectors in Java, how to return multiple vectors in an object

    <p>I'm working on a java program, and I have several vectors defined and filled (from a file) inside a method. I need to return the contents of all the vectors from the method. I have heard you can put them all in one object to return them. Is that possible, and if so, how? If not, do you have any possible solutions for me? Thanks in advance for your help! </p> <p>Here is a code snippet:</p> <pre><code>Object getInventory() { Vector&lt;String&gt; itemID=new Vector&lt;String&gt;(); Vector&lt;String&gt; itemName=new Vector&lt;String&gt;(); Vector&lt;Integer&gt; pOrdered=new Vector&lt;Integer&gt;(); Vector&lt;Integer&gt; pInStore=new Vector&lt;Integer&gt;(); Vector&lt;Integer&gt; pSold=new Vector&lt;Integer&gt;(); Vector&lt;Double&gt; manufPrice=new Vector&lt;Double&gt;(); Vector&lt;Double&gt; sellingPrice=new Vector&lt;Double&gt;(); Object inventoryItem=new Object(); //object to store vectors in try { Scanner infile= new Scanner(new FileReader("Ch10Ex16Data.txt")); int i=0; while (infile.hasNext()) { itemID.addElement(infile.next()); itemName.addElement(infile.next()+infile.nextLine()); pOrdered.addElement(infile.nextInt()); pInStore.addElement(pOrdered.elementAt(i)); pSold.addElement(0); manufPrice.addElement(infile.nextDouble()); sellingPrice.addElement(infile.nextDouble()); i++; } infile.close(); System.out.println(itemID); System.out.println(itemName); System.out.println(pOrdered); System.out.println(pInStore); System.out.println(pSold); System.out.println(manufPrice); System.out.println(sellingPrice); } catch (Exception f) { System.out.print(f); } return inventoryItem; } </code></pre>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
