title: "Main method not found" error when starting program?
body: <p>I'm learning Java for my course and I've hit a brick wall. I've been tasked with developing a simple command line program. To make things easier I was given the following sample code to modify so I wouldn't have to start from scratch.</p>
  
  <pre><code>package assignment;
  
  public class Main {
  private final static String[] mainMenuOpts = {"Students","Lecturers","Admin","Exit"};
  private final static String[] studentMenuOpts = {"Add Student","List all Students","Find a Student","Return to Main Menu"};
  private Menu mainMenu = new Menu("MAIN MENU",mainMenuOpts);
  private Menu studentMenu = new Menu("STUDENT MENU",studentMenuOpts);
  private DataStore data = new DataStore();
  private java.io.PrintStream out = System.out;
  private ReadKb reader = new ReadKb();
  /** Creates a new instance of Main */
  public Main() {
      run();
  }
  
  private void run(){
      int ret = mainMenu.display();
      while(true){
          switch(ret){
              case 1: students();break;
              case 2: lecturers(); break;
              case 3: admin(); break;
              case 4: exit(); break;
          }
          ret = mainMenu.display();
      }
  }
  private void students(){
      int ret = studentMenu.display();
      while(ret != 4){
          switch(ret){
              case 1: addStudent();break;
              case 2: listStudents(); break;
              case 3: findStudent(); break;
          }
          ret = studentMenu.display();
      }
  }
  private void lecturers(){
      out.println("\nLecturers not yet implemented");
  }
  private void admin(){
      out.println("\nAdmin not yet implemented");
  }
  //Student methods
  private void addStudent(){
      out.println("\n\tAdd New Student");
      //prompt for details
      //add student to the datastore
      //ask if they want to enter another student - 
      // if so call addStudent again
      //otherwise the method completes and the studentMenu will display again
  
  }
  private void listStudents(){
      out.println("\n\tStudent Listing");
      //list all students from the datastore
  }
  private void findStudent(){
      out.println("\n\tFind Student");
      out.print("Enter Search String: ");
      //reasd search text
      //use datastore method to get list of students that contain the search string
      //display matching students
  
  }
  // end Student methods
  private void exit() {
      data.save();  //call the datastore method that will save to file
      out.println("\n\nGoodbye :)");
      System.exit(0);
      }
  }
  </code></pre>
  
  <p>I'm using NetBeans and when I try to run the project I get this error:</p>
  
  <pre><code>Error: Main method not found in class assignment.Main, please define the main method as: public static void main(String[] args)
  </code></pre>
  
  <p>I just want to get the program running so I can understand the code better. I understand the error, but have no idea where to implement the main method in this wall of text. I've been experimenting for hours, but obviously as a newbie I'm completely useless. Any help would be greatly appreciated.</p>
