Answer 1

"//*[@id='sb_ifc0']" is the xpath of the div within which the search text field of Google is placed.

Replace the div's xpath with the xpath of the search text field and try to run your test. I think it should work.

Change,

driver.findElement(By.xpath("//*[@id='sb_ifc0']")).sendKeys("calculator");

To one of these,

driver.findElement(By.xpath(".//*[@id='gs_htif0']")).sendKeys("calculator");

driver.findElement(By.xpath(".//*[@id='lst-ib']")).sendKeys("calculator");

driver.findElement(By.name("q")).sendKeys("calculator");

Answer 2

Sumit,

The problem is happening because the sendKeys method must be used upon a input field.

The actions you must take are the following:

1. Go to Google page
2. Wait until the search bar (id:sb_ifc0) is visible (See this article)
3. Click on the search bar (id:sb_ifc0) in order to enable the text input
4. Fill in the search input (id:lst-ib)

It's always good to wait for visibility of the elements you are going to interact.
