    <p>When learning the language (and after learning too) it helps to have small part of code, that is easy to write , test and maintain. For example comparing a number and remembering could moved to another class and tested.</p> <p>I did not intend to correct your programming error. I would like to take a note on good programming practices <a href="http://rads.stackoverflow.com/amzn/click/0132350882" rel="nofollow">to write better code</a> .</p> <pre><code>import java.io.File; import java.io.IOException; import java.util.Scanner; public class LargenSmall { BigHolder bigHolder= new BigHolder(); SmallHolder smallHolder = new SmallHolder(); public static void main(String[] args) throws IOException { new LargenSmall().doSearch(args[0]); } void doSearch (String filename) throws IOException { //Open the file File file = new File(filename); Scanner inputFile = new Scanner(file); iterateAndFetchNumbers(inputFile); inputFile.close(); printResult(); testNumbers(); } private void iterateAndFetchNumbers(Scanner inputFile) { //Read all the values in Numbers file and find the highest value while (inputFile.hasNext()) { //Read the numbers in the file and compare each value to find highest value double number = inputFile.nextDouble(); smallHolder.accept(number); bigHolder.accept(number); } } private void printResult() { //Print out the lowest value in the list System.out.println("The lowest number in your file called, " + "Numbers.txt is " + smallHolder.small + "."); //Print out the highest value in the list System.out.println("The highest value in the list is " + bigHolder.big); } // private static class SmallHolder { double small= Double.POSITIVE_INFINITY; public void accept(double newNumber) { if ( newNumber &lt; small) { small = newNumber ; } } } private static class BigHolder { double big= 0; public void accept(double newNumber) { if ( newNumber &gt; big ) { big = newNumber ; } } } //self test example - should be in junit class public void testNumbers() { BigHolder b = new BigHolder(); b.accept(1); b.accept(3); b.accept(8); b.accept(0); b.accept(100); assert b.big == 0;//junit assert really } } </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.
