    text
    copied!<p>I have a project created in netbeans and when i compiled it created class files which is fine. But if i have a file called operator.java after compiling i got operator.class, operator$1.class, operator$2.class and so on.. Is there any particular reason for doing it ? can you explain me why is it happening ?</p> <pre><code>package admin; import forms_helper.global_variables; import java.sql.ResultSet; import java.sql.SQLException; import java.util.ArrayList; import java.util.List; import java.util.logging.Level; import java.util.logging.Logger; import utilities.mysql_query; import utilities.variables; public class stock_adjust extends javax.swing.JFrame {` List&lt;String&gt; list = new ArrayList&lt;String&gt;(); List&lt;String&gt; list_id = new ArrayList&lt;String&gt;(); List&lt;String&gt; list_quantity = new ArrayList&lt;String&gt;(); /** Creates new form stock_adjust */ public stock_adjust() { initComponents(); } /** This method is called from within the constructor to * initialize the form. * WARNING: Do NOT modify this code.
