Remove Null Value from String array in java

Question

How to remove null value from String array in java?

String[] firstArray = {\"test1\",\"\",\"test2\",\"test4\",\"\"};

I need the \"firstArra

Answer 1

Those are zero-length strings, not null. But if you want to remove them:

firstArray[0] refers to the first element
firstArray[1] refers to the second element

You can move the second into the first thusly:

firstArray[0]  = firstArray[1]

If you were to do this for elements [1,2], then [2,3], etc. you would eventually shift the entire contents of the array to the left, eliminating element 0. Can you see how that would apply?
