Selenium Webdiver- Writing function inside a function - function

Question

I would like automate a drag and drop functionality. I have written a function for that. In that function there is two activites
1. Get the drag-from and drag-to element
2. Perform the drag and drop
can i write this as two sub functions inside ?
The following is the code:
public class dunelmtest {
static WebDriver driver= new FirefoxDriver();
#Test
public void test() {
DragandDrop();
}
public static void DragandDrop(){
driver.manage().window().maximize();
driver.get("http://marcojakob.github.io/dart-dnd/basic/");
driver.manage().timeouts().implicitlyWait(20, TimeUnit.SECONDS);
// Want a sub function for this
//Locate element which you wants to drag.
WebElement dragElementFrom = driver.findElement(By.xpath("//img[#class='document']"));
//Locate element where you wants to drop.
WebElement dropElementTo = driver.findElement(By.xpath("//div[#class='trash']"));
// Want another sub function fir this
//Use Actions class and Its members of WebDriver API to perform drag and drop operation.
Actions builder = new Actions(driver);
Action dragAndDrop = builder.clickAndHold(dragElementFrom)
.moveToElement(dropElementTo)
.release(dropElementTo)
.build();
dragAndDrop.perform();
}
}
So how can i create two sub function inside DragandDrop?

Answer 1

I'm not sure if i understand your Question clearly but from what i can understand you want to do something more of a Fluent, the snippet below shows a Class structure that should help you achieve what you want.
Hope this helps
Public class DragandDrop{
public DragandDrop LocateElement(By locator){
//Implementation
return this;
}
public DragandDrop DragElement(toElement){
//Implementation
return this;
}
}
