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

Here I have a program called Connect4Model. Basically what the problem is that I have successfully compiled the program in TextPad. However when I run the program it throws up an Exception in thread "main" error. I fully understand what this error is, and it basically means that I'm missing the main method as shown below. However what I can see is how I can implement this. If there is a possible solution this would be great.

Thanks

Code :

---

public class Connect4Model
{
	Connect4Column [] columns;
	int my_array[];
	private int NUM_COLUMNS;
	private int NUM_ROWS;
	private int playerToGoNext = Connect4Column.RED_COUNTER;
 
	Connect4Model(int numCols, int numRows)
	{
		columns = new Connect4Column[NUM_COLUMNS];
 
		for (int i = 0;i < NUM_COLUMNS;i++)
		{
			columns[i] = new Connect4Column(NUM_ROWS);
		}
	}
	int getNumCols()
	{
		return 0;
	}
	int getNumRows()
	{
		return 0;
	}
	int getNextPlayer()
	{
		return 0;
	}
	boolean go(int thisColumn)
	{
		if ( thisColumn < 0 ||  thisColumn >= NUM_COLUMNS)
		{
			return false;
		}
 
		else  if(my_array[thisColumn] >= NUM_ROWS)
		{
			return false;
		}
		else
		{
			my_array[playerToGoNext]++;
			return true;
		}
	}
	int getCounter(int thisColumn, int thisRow)
	{
		return 0;
	}
	int getNumCounters(int thisColumn)
	{
		if(thisColumn >= 0 && thisColumn < NUM_COLUMNS)
		{
			return my_array[thisColumn];
		}
		else
		{
			return 0;
		}
	}
 
}

Hello dj118, welcome to the forums.

Seeing as this thread is about Exceptions. I have moved it here: Exceptions - Java Programming Forums

Can we see the Connect4Column class?

Sure you can see the Connect4Class. I've attached my code on the following link, as I don't know how to put the code within the tags. Java | public class Connect4Column { - Anonymous - 1A1PadCq - Pastebin.com

Code :

---

public class Connect4Column
{
	private int counters[];
	private int numCounters;
	private int MAX_NUM_COUNTERS;
 
	static int YELLOW_COUNTER = 1;
	static int RED_COUNTER = 2;
 
	public Connect4Column(int max_counters)
	{
		MAX_NUM_COUNTERS = max_counters;
		counters = new int[MAX_NUM_COUNTERS];
		numCounters = 0;
	}
 
	public boolean addCounter(int thisCounter)
	{
		if ((numCounters < MAX_NUM_COUNTERS)&&((thisCounter == 1)||(thisCounter == 2)))
		{
			counters[numCounters] = thisCounter;
			numCounters++;
			return true;
		}
		else
		{
			return false;
		}
	}
 
	public int getNumCounters()
	{
		return numCounters;
	}
 
	public int getCounter(int thisRow)
	{
		if ((thisRow >= 0)&&(thisRow <= numCounters))
		{
			return counters[thisRow];
		}
		else
		{
			return 0;
		}
	}
}

I don't know if this is the correct way of putting the code into the CODE tags. But the link is also avaliable
