misc : What is RWD

RWD

What is Responsive Web Design?

 

 A responsive website changes its appearance and layout based on the size of the screen the website is displayed on.

 

 Responsive sites can be designed to make the text on the page larger and easier to read on smaller screens. They can also be configured to make the buttons on the phone's screen easier to press.

Misc : What is BootStrap

Boot Strap

" it's a simple file that starts a large process."

 

"Rather than the user downloading the entire app, including features he does not need, and re-downloading and manually updating it whenever there is an update, the user only downloads and starts a small "bootstrap" executable, which in turn downloads and installs those parts of the application that the user needs. Additionally, the bootstrap component is able to look for updates and install them each time it is started."

 

"...is a technique by which a simple computer program activates a more complicated system of programs."

 

"A different use of the term bootstrapping is to use a compiler to compile itself, by first writing a small part of a compiler of a new programming language in an existing language to compile more programs of the new compiler written in the new language."

Selenium : Hash Code

Hash Code

A hashcode is a number generated from any object. This is what allows objects to be stored/retrieved quickly in a Hashtable.

Imagine the following simple example:

On the table in front of you have 9 boxes, each marked with a number 1 to 9. You also have a pile of wildly different objects to store in these boxes, but once they are in there you need to be able to find them as quickly as possible.

What you need is a way of instantly deciding which box you have put each object in. It works like an index; you decide to find the cabbage so you look up which box the cabbage is in, then go straight to that box to get it.

Now imagine that you don't want to bother with the index, you want to be able to find out immediately from the object which box it lives in.

In the example, let's use a really simple way of doing this - the number of letters in the name of the object. So the cabbage goes in box 7, the pea goes in box 3, the rocket in box 6, the banjo in box 5 and so on. What about the rhinoceros, though? It has 10 characters, so we'll change our algorithm a little and "wrap round" so that 10-letter objects go in box 1, 11 letters in box 2 and so on. That should cover any object.
Sometimes a box will have more than one object in it, but if you are looking for a rocket, it's still much quicker to compare a peanut and a rocket, than to check a whole pile of cabbages, peas , banjos and rhinoceroses.

That's a hash code. A way of getting a number from an object so it can be stored in a Hashtable. In Java a hash code can be any integer, and each object type is responsible for generating its own. Lookup the "hashCode" method of Object.

Selenium : Creating Object Repository

Creating Object Repository

Since the "OR" File resides in the same package there is no need to import .


------------------------File Name : Sample1.java --------------------File1
public class Sample1
{
    public static void main(String[] args)   
    {       
        WebDriver oDriver=new FirefoxDriver();
        oDriver.get("https://www.google.co.in");
        WebElement oTitle=oDriver.findElement(By.xpath(OR.button));  // Directly using the static variable     }
}

===================================================================

------------------------File Name : OR .java--------------------File2
public class OR {

          public static final String button="//button[@id='gbqfba']";
       
}
===================================================================

Selenium : Final Keyword

Selenium : Final Keyword

Final is different than finally keyword which is used on Exception handling in Java. 

Final variable 

1. It must be initialized at the time of declaration or inside constructor. 
2. Once you make a initialized final you are not allowed to change it and compiler will raise compilation error if you try to re-initialized final variables in java. 
3. Final variables are often declare with static keyword in java and treated as constant. 

Example :

public static final String sVar = "some_Data";
sVar = "HI"; //invalid compilation error

sVar = new String("new_data"); //invalid compilation error

  final method

1. Final keyword in java can also be applied to methods.
2.  You should make a method final in java if you think it’s complete and its behavior should remain constant in sub-classes. 
3. Final methods are faster than non-final methods because they are not required to be resolved during run-time and they are bonded on compile time.

Example:

class Loan

 {

 public final String getName()

{

     return "personal loan";

 }

}

class PersonalLoan extends Loan

 {

    @Override

    public final String getName()

 {

        return "cheap personal loan"; //compilation error: overridden method is final

    }

}

  final Class in Java

1.   Final class is complete in nature and can not be sub-classed or inherited. 
2. Several classes in Java are final e.g. String, Integer and other wrapper classes. 

Example :

final class Loan

 {

}

class PersonalLoan extends Loan 

{  //compilation error: cannot inherit from final class

 

}

Benefits of final keyword in Java

1. Final keyword improves performance.

2. Final variables are safe to share in multi-threading environment without additional synchronization overhead.

 

Selenium : HighLighting WebElements
