How to handle multiples windows if they open at different places not all together.

import org.openqa.selenium.WebDriver;
import org.openqa.selenium.firefox.FirefoxDriver;

public class Naukari {
    public static void main(String[] args) {
        WebDriver driver = new FirefoxDriver();
        driver.get("http://www.naukri.com/");
        driver.manage().timeouts().implicitlyWait(10, TimeUnit.SECONDS);
        //Click on Employer's Zone
        driver.findElement(By.xpath(".//*[@id='empNavM']/ul/li[1]/a")).click();
       
        switchControlToLatestWindow(driver); //switch control to Employer's Zone window
   
        driver.findElement(By.xpath("//div[@class='headbg']//a[text()='Report a Problem']")).click(); //click on 'Report a Problem'
        //this will again open a new window
        switchControlToLatestWindow(driver); //switch control to 'Report a Problem' window
       
        driver.findElement(By.xpath("//input[@name='strName']")).sendKeys("jdhjhgdjhgj1222"); //pass some value to Your name field to confirm our control is there
}
    //this is a method to switch the control to the latest opened window
    public static void switchControlToLatestWindow(WebDriver driver){
        Iterator<String> browsers = driver.getWindowHandles().iterator();
        while(browsers.hasNext()){
            driver.switchTo().window(browsers.next());
        }
    }

}

Suppose there are five Browser windows opened, how to find the third one and close it through web driver ?

1st get the address of all the browsers using

Iterator<String> windows = driver.getWndowHandles().iterator();

Now suppose you want to close the window whose title is "abc";

while(windows.next()){
         driver.switchTo().window(windows.next());
         String title = driver.getTitle();
         if(title.equals("abc")){
                driver.close();
                 break;
          }
}

or say if you want to close 3rd one by force and you don't know the expected title then

for(int i=0; i<3; i++){
         driver.switchTo().window(windows.next());
         if(i==2){
                driver.close();
                 break;
         }
}


or you can do the same -


for(int i=0; i<3; i++){
          String child = windows.next();
         if(i==2){
                 driver.switchTo().window(child);
                driver.close();
                 break;
         }
}

Switch to window then frame then again switch back to frame and window. (complex example)

Note- Please do the manual steps first and see how the flow going then try with the script.
Manual Steps-
1) open google
2) type in search box 'times of india'
3) click on 1st link of 'times of india'
4) click on 'click here to go to timesofindia.com'
5) click on 'Login' button (which is in the top just beside the LogIn with Facebook)
6) click on facebook
7) check the checkbox in facebook page and click on cancle
8) then close the frame (which has 3 options facebook, twitter and your email)
9) click on india in main page.
10) close the browser.

        driver.manage().timeouts().implicitlyWait(3, TimeUnit.MINUTES);
        driver.get("https://www.google.co.in/"); //open google
        driver.findElement(By.id("gbqfq")).sendKeys("times of india"); //type in search box 'times of india'
        driver.findElement(By.xpath("//span[text()='times of india']")).click(); //click on 1st link of 'times of india'
        driver.findElement(By.xpath("//div[div[div[div[cite[b[text()='indiatimes']]]]]]//a[text()='The ']")).click(); //click on 'click here to go to timesofindia.com'
        driver.findElement(By.linkText("Log In")).click(); //click on 'Login' button
        driver.switchTo().frame(driver.findElement(By.xpath("//iframe[@id='signupsso']"))); //now switch to login frame which has 3 options facebook, twitter and your email
        driver.findElement(By.id("fb")).click(); //click on facebook which will open in new window
        Iterator<String> it = driver.getWindowHandles().iterator();// get the address of all the windows
        String times = it.next();
        String fb = it.next();
        driver.switchTo().window(fb); // switch to facebook window
        driver.findElement(By.xpath("//input[@type='checkbox']")).click(); //check the checkbox in facebook window
        driver.findElement(By.xpath("//input[@value='Cancel']")).click(); //click on cancle button in facebook window
        driver.switchTo().window(times); //switch back to main window
        driver.switchTo().frame(driver.findElement(By.xpath("//iframe[@id='signupsso']"))); //again switch to login frame which has 3 options facebook, twitter and your email
        Thread.sleep(2000);
        driver.findElement(By.xpath("//img[@src='/photo/11509366.cms']")).click(); // click on cross sign to close frame
        Thread.sleep(2000);
        driver.switchTo().defaultContent(); //switch back to main page
        driver.findElement(By.xpath("//div[ul[script[text()='sectionid=4719157']]]//a[@href='/india/indiaarticlelist/-2128936835.cms']")).click(); //click on india
        driver.close();
    }

}

switch to window then frame.

Note- This is to login for HDFC credit card.

        System.out.println("give your hdfc credit card userid: ");
        String userid = in.next();
        System.out.println("give your pass: ");
        String pass = in.next();
        WebDriver driver = new FirefoxDriver();
        driver.manage().timeouts().implicitlyWait(20, TimeUnit.SECONDS);
        driver.get("http://www.hdfcbank.com/");
        driver.findElement(By.xpath("//img[@src='/assets/images/login_butn.png']")).click();
        Iterator<String> browser = driver.getWindowHandles().iterator();
        String parent = browser.next();
        String child1 = browser.next();
     
        driver.switchTo().window(child1);
        driver.findElement(By.xpath("//img[@src='/assets/images/netbanking_continue_red.gif']")).click();
        driver.switchTo().frame(driver.findElement(By.xpath("//frame[@src='RSLogin.html']")));
        driver.findElement(By.xpath("//p[strong[text()='Credit Cardholders']]//a[text()='click here']")).click();
     
        Iterator<String> browser1 = driver.getWindowHandles().iterator();
        String child2=null;
        while(browser1.hasNext())
        {
             child2 = browser1.next();
        }
        driver.switchTo().window(child2);
        driver.findElement(By.xpath("//input[@name='fldLoginUserId']")).sendKeys(userid);
