Can't scroll using arrows on excel

Usually, I use my arrow keys to navigate through my excel but lately, they (arrow keys) haven't been really helpful. Like at all!

The issue was I had the scroll lock "on". But I am on Windows 10 and I can't see the scroll lock function key anywhere :O

Here is how you can turn off the scroll key on Windows 10:

Press the Windows key.
Type onscreen keyboard and press Enter.
When the onscreen keyboard appears, your ScrLk (Or scroll lock button) will be highlighted which means it was turned on. Click the ScrLk button to turn it off.
Go back to your excel and you should now be able to use your excel.

Hope this helps!

Apache Commons StringUtils.isEmpty() vs Java String.isEmpty()

You might want to test for if a String is empty many a times. Before we jump onto the numerous solutions available let us take a look at how we define “Empty String” The difference in the two methods given by Apache and Java are dependent on how we define an empty string. Java String.isEmpty returns a boolean true if the string’s length is zero. If the string has null it throws NullPointerException Apache StringUtils.isEmpty returns a boolean true if the string is either null or has length is zero Thus its purely dependent on how you are defining “empty string” in your program which will decide which function to use…BTW if you want to skip using Apache Commons funciton and would want to stick to java then you can have your own function like this: public static boolean isEmptyOrNull(String strStringToTest) { return strStringToTest == null || strStringToTest.trim...
