I get NoSuchMethodError but cant run program with Static

Question

Hi, I got this silly problem. My program is meant to display a input dialog an then write to a file. Sounds so simple. But java wanted to make things hard for me and i got a NoSuchMethodError. I know that i am meant to us Public Static Void Main (String arg) but when i do this i get error "this can be referenced as static". Here is the source, do you know how to fix this.(an how can i?)
Thnx
My Regards
import java.io.*;
import java.awt.event.*;
import javax.swing.*;
import java.lang.String;
public class sender implements Runnable {
int i= 0;
String mes;
public void main (String[] arguments) {
Thread th = new Thread (this);
th.start ();
//sender();
while (true){}
public void start () {
Thread th = new Thread (this);
th.start ();
public void run() {
try {
Thread.sleep(3000);
} catch (InterruptedException e) {}
String mesdialog = JOptionPane.showInputDialog(null,
"Enter your message");
mes = mesdialog.toString();
try {
//FileOutputStream of = new
//FileOutputStream ("send.txt");
FileWriter of = new
FileWriter("send.txt");
//BufferedReader in = new
// BufferedReader(fr);
//while (true) {
int i = 66;
boolean eof = false;
int inChar = 0;
do {
inChar = mes.hashCode();
if (inChar != -1) {
char outChar = (char)inChar ;
of.write(outChar);
//of.write(mes,0,20);
} else
eof = true;
} while (!eof);
//outfile.write(input);
} catch (IOException e) {
System.out.print("AAA ERROR");}
}

public static void main (String[] arguments) {
Thread th = new Thread (new sender());
th.start ();
//sender();
while (true){}
}You can't reference "this" from a static context. main is required to
be static.
