"else" without "if" error.....

[hipopony66]

I can not figure out what is wrong with this. Could someone please have a look and help me out. I know this is not the most efficient way to do this, but I just need to find my errors. Any help is extremely appreciated.

Here's the code:

import javax.swing.*;                                 //make swing available
public class LeapYear
{

public static void main (String args[])              //main method

{                                                   //start the main method

int montIn, yearIn, secondCheck, finalCheck;
boolean isLeapYear;


monthIn=JOptionPane.showInputDialog("Enter the month as an integer:");    //ask for month input

	if (monthIn==0)                                                   //exit the program if the month is 0
		System.exit(0);
	  
yearIn=JOptionPane.showInputDialog("Enter the Year (4 digits):");         //ask for year input

checkLeapYear=yearIn%4;                                                   //check to see if year is a leap year

if (checkLeapYear==0)                                //The year is possibly a leap year; do some more checking

	secondCheck=yearIn%100;                      //is it divisible by 100?
	
		if (secondCheck==0)                                       //is divisible by 100, do some more checking
		  finalCheck=yearIn%400;                                 //is it divisible by 400?
		  	  if (finalcheck==0)                            //is divisible by 400, passes test!
			   isLeapYear=True;                             //the year is a leap year
   	     else                                                     //year is not divisible by 100
				isLeapYear=False;
		  
else 	                                                             //The Year is NOT a leap year (not divisible by 4)
isLeapYear=False;

{                                                  //start new method
if (isLeapYear=="True")                           //The Year is a leap year
