Access Modifiers in Java

We always use Public, Private, Protected in our Selenium scripts. Before using these, we should know how and where to use these access modifiers. Here is the table showing where we can call these modifiers:

Access Modifier	within class	within package	outside package by  subclass only	outside  package
Private	Y	N	N	N
Default	Y	Y	N	N
Protected	Y	Y	Y	N
Public	Y	Y	Y	Y

How to setup Classpath for Java in Windows 7?

We all know the importance of CLASSPATH for Java. Setting PATH/CLASSPATH is very easy if we have the correct steps. I've listed down the steps which will help you to set CLASSPATH/PATH for Java:

 

Step 1: Download Java or JDK from the following URL according to your computer configuration:

http://www.oracle.com/technetwork/java/javase/downloads/index.html

Step 2: Install it by click on setup.exe and following the steps.

Step 3: By default JDK installs at "C:\Program Files\Java\jdkxxx.xx" location only. Unless we change the location at the time of installation.

Step 4: Go to JDK installed location, open bin folder available at the location. Now, copy the path.

Step 5: Right-click on My Computer icon available at your desktop and select Properties.

Step 6: Now, click on Advanced System Settings and click on Advanced tab from the dialog box opened

Step 7: Click on Environment Variables and then System Variables.

Step 8: Edit path and add the copied bin (which we did in Step 4) in that. Below are some images to help you:

Step 9: Click on OK of Environment Variables window and System Properties window.

Step 10: To verify whether Classpath or path of java is set up correctly or not.

Open Command Prompt and enter java -version. You'll find a statement like mentioned below:

java version "1.7.0_45"

Java(TM) SE Runtime Environment (build 1.7.0_45-b18)

What is HTMLUnitDriver?

HTMLUnitDriver is fastest (50% faster than Firefox), lightweight, platform independent. However, we don't use it. We always prefer to use Firefox, Chrome, IE but not HTMLUnitDriver.

Chrome and Internet Explorer driver

Download 32 Bit Chrome Driver by clicking on below Download link:

DOWNLOAD

You can use 32 Bit Chrome Driver on 32 Bit as well as 64 Bit Windows. There is no 64-bit Chrome on Windows yet (See this ticket), as a result there is no ChromeDriver for 64-bit Windows.

Here 32/64 bit are in terms of browser's architecture, not the OS.
