    <p>I have been working on this program for quite sometime and my brain is fried. I could use some help from someone looking in.</p> <p>I'm trying to make a program that reads a text file line by line and each line is made into an <code>ArrayList</code> so I can access each token. What am I doing wrong? </p> <pre><code>import java.util.*; import java.util.ArrayList; import java.io.*; import java.rmi.server.UID; import java.util.concurrent.atomic.AtomicInteger; public class PCB { public void read (String [] args) { BufferedReader inputStream = null; try { inputStream = new BufferedReader(new FileReader("processes1.txt")); String l; while ((l = inputStream.readLine()) != null) { write(l); } } finally { if (inputStream != null) { inputStream.close(); } } } public void write(String table) { char status; String name; int priority; ArrayList&lt;String&gt; tokens = new ArrayList&lt;String&gt;(); Scanner tokenize = new Scanner(table); while (tokenize.hasNext()) { tokens.add(tokenize.next()); } status = 'n'; name = tokens.get(0); String priString = tokens.get(1); priority = Integer.parseInt(priString); AtomicInteger count = new AtomicInteger(0); count.incrementAndGet(); int pid = count.get(); System.out.println("PID: " + pid); } } </code></pre> <p>I am about to poke out my eyeballs. I got three errors:</p> <pre><code>U:\Senior Year\CS451- Operating Systems\Project1 PCB\PCB.java:24: unreported exception java.io.IOException; must be caught or declared to be thrown inputStream.close();} ^ U:\Senior Year\CS451- Operating Systems\Project1 PCB\PCB.java:15: unreported exception java.io.FileNotFoundException; must be caught or declared to be thrown inputStream = new BufferedReader(new FileReader("processes1.txt")); ^ U:\Senior Year\CS451- Operating Systems\Project1 PCB\PCB.java:18: unreported exception java.io.IOException; must be caught or declared to be thrown while ((l = inputStream.readLine()) != null) { ^ </code></pre> <p>What am I doing wrong?</p>

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.
