Body
You need to read the file line by line. It is done with a <code>BufferedReader</code> like this : <pre><code>try { FileInputStream fstream = new FileInputStream("input.txt"); BufferedReader br = new BufferedReader(new InputStreamReader(fstream)); String strLine; int lineNumber = 0; double [] a = null; double [] b = null; // Read File Line By Line while ((strLine = br.readLine()) != null) { lineNumber++; if( lineNumber == 4 ){ a = getDoubleArray(strLine); }else if( lineNumber == 5 ){ b = getDoubleArray(strLine); } } // Close the input stream in.close(); //print the contents of a for(int i = 0; i < a.length; i++){ System.out.println("a["+i+"] = "+a[i]); } } catch (Exception e) {// Catch exception if any System.err.println("Error: " + e.getMessage()); } </code></pre> Assuming your <code>"a"</code> and<code>"b"</code> are on the fourth and fifth line of the file, you need to call a method when these lines are met that will return an array of <code>double</code> : <pre><code>private static double[] getDoubleArray(String strLine) { double[] a; String[] split = strLine.split("[,)]"); //split the line at the ',' and ')' characters a = new double[split.length-1]; for(int i = 0; i < a.length; i++){ a[i] = Double.parseDouble(split[i+1]); //get the double value of the String } return a; } </code></pre> Hope this helps. I would still highly recommend reading the Java <a href="http://download.oracle.com/javase/tutorial/essential/io/" rel="nofollow">I/O</a> and <a href="http://download.oracle.com/javase/tutorial/java/data/strings.html" rel="nofollow">String</a> tutorials.

Guidance

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.
