In this article I will tell you how we can do web automation using selenium in JAVA.
Once you have these softwares with you, You can follow below steps.

//Install selenium 2.0 -> https://code.google.com/p/selenium/downloads/list

// List of common operations on web elements
//***********************************************************************
//We will see lot of operation that can be done in selenium
//1.Clicking on the WebElement.
//2.Enter value in editbox WebElement.
//3.Select value from the dropdown WebElement.
//4.Select radiobutton WebElement.
//5.Select the checkbox WebElement.
//6.Clicking/accessing hidden WebElements. -> Make them visible first and then click
//7.How to check if element exists in page.
//8.reading data from table rows, cells etc.
//9.Different ways of accessing elements.
//10.Synchronization methods in selenium in Java.

//1."Element is not clickable at point (x, y).
//2.No Such Element - for Frame related issue
//3.The driver executable does not exist
//4.Driver executable must be set by the webdriver.ie.driver system property
//5.The path to the driver executable must be set by the webdriver.chrome.driver system property
