Java split String that start with space [duplicate]

Question

I know how to split a string by space as the following:

String[] array = string.split(" ");

This works great until I try to split string that starts with a space like

" I like apple"

The result looks something like this:

{"", "I", "like", "apple"}

How can I split the string so it only keeps strings that is not empty?

Trim the string first.

You can call string.trim()and then string.split(" "). The trim() method removes spaces before the first non-space-character and after the last non-space-character.

To remove leading and trailing spaces, you can use .trim().

String[] array = string.trim().split(" ");
