Exception in thread "main" java.lang.NoSuchMethodError: main -- Help

Question

I am new to Java programming and I have been working out of a book trying to learn the language. I am working on a Ubuntu system using Eclipse. I get an error when I try to run this app. It is: Exception in thread "main" java.lang.NoSuchMethodError: main. I have Googled it and read different possible solutions, but none have helped. Can someone help me solve this?
Here is the code for battleshipGameTestDrive.java:_
import java.util.ArrayList;
public class battleshipGameTestDrive
     public static void main(String[] args, ArrayList<String> locations)      
          int numOfGuesses = 0;
          boolean isAlive = true;
          GameHelper helper = new GameHelper();
          battleshipGame ship = new battleshipGame();
          for (int ctr = 1; ctr < 4; ctr++)
               int randomNum = (int) (Math.random() * 5);          
               locations.add(Integer.toString(randomNum));
               ship.setLocationCells(locations);
          while (isAlive == true){
               String userGuess = helper.getUserInput("Enter a number (1-7): ");
               numOfGuesses++;
               String result = ship.checkYourself(userGuess);
               if (result.equals("kill")){
                    isAlive = false;
                    System.out.println("You took " + numOfGuesses + " guesses");
               } // close result if
          }  //end while loop
     }// end of main
}// end of battleshipGameTestDrive class
Here is the code for the battleshipGame class.java:_
import java.util.ArrayList;
public class battleshipGame {
     private ArrayList<String> locationCells;
     public void setLocationCells(ArrayList<String> loc){
          locationCells = loc;
     public String checkYourself(String userInput){
          String result = "miss";          
          int index = locationCells.indexOf(userInput);
          if (index >= 0){
               locationCells.remove(index);
               if (locationCells.isEmpty()){
                    result = "kill";
               }else{
                    result = "hit";
               }// close if
          }// closer outer if
          return result;
     }     //close method
}     //close class

Hello,
I saw your short message youe sent to someone who had a problem : Exception in thread "main" java.lang.NoSuchMethodError :main
So I was thinking maybe you could help me I struggle with this code fro 3weeks, this is a code I save it later as

import java.awt.event.*;
class Party {
public void makeInvitation(){
Frame f = new Frame();
Label l = new Label("Party at Tom's");
Button b = new Button("Sure");
Button c = new Button("Noo...");
Panel p = new Panel();
p.add(l);
I write this code in Notepad++ than I save it as java file with looks like this : Java source file (*.java)
- than in Command Prompt I write : javac Party.java as usual and it comes with this error below Exception in thread "main" .......
