Problem with JMenus

I have this code

import java.io.*;

import java.util.*;

import javax.swing.*;

import java.awt.*;

import java.awt.event.*;

publicclass rCalc

{

//JFrame

JFrame mainFrame =new JFrame("Acidmods Resistance Calculator");

//JmenuBar

JMenuBar menuBar =new JMenuBar();

//JMenu

JMenu menu =new JMenu("Calculators");

menuBar.add(menu);

//Menu Items

JMenuItem resI =new JMenuItem("Resistence");

menu.add(resI);

//Main

publicstaticvoid main(String[] args)

{

}

}

but when i try to compile it i get these errors

<identifier> expectedline 18

<identifier> expectedline18

<identifier> expectedline22

<identifier> expectedline22

What is wrong with it?
