I am using Eclipse as an Ide.</p> <p>I want to enter three values and then to print the smallest one.</p> <p>Here is my code:</p> <pre><code>import java.util.Scanner; public class CompareValues { public static void main( String[] args ) { System.out.println(); System.out.println( "The smallest number is: " ); int first; int second; int third; checkMethod( first, second, third ); } static int checkMethod( int firstNumber, int secondNumber, int thirdNumber ) { Scanner input = new Scanner( System.in ); System.out.println( "Enter three nubmers between 1 - 100: " ); firstNumber = input.nextInt(); secondNumber = input.nextInt(); thirdNumber = input.nextInt(); if ( ( 0 &lt; firstNumber ) || secondNumber || ( thirdNumber &gt; 100 ) ) { System.out.println( "Invalid entry: enter numbers between 1 and 100 only: " ); } } static int compareMethod( int first, int second, int third ) { if ( ( first &lt; second ) &amp;&amp; ( first &lt; third ) ) { return first; } else if ( ( second &lt; first ) &amp;&amp; ( second &lt; third ) ) { return second; } else { return third; } } } </code></pre> <p>When I compiled the code I got this message:</p> <blockquote> <p>Exception in thread "main" java.lang.Error: Unresolved compilation problems: The local variable first may not have been initialized The local variable second may not have been initialized The local variable third may not have been initialized at CompareValues.main(CompareValues.java:11) </p> </blockquote>

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.
