Question

I need to trim a given code in Java after the first whitespace.
ex. if i have a String (call it inputstartString) with the value

1 100 2 34

I need to get the second number (number 100 in this case)
I thought this would go with a trim, but i have absolutely no clue how to do it in this case,
afterward I need to do it for the following numbers as well, but I guess once I learn how it goes I can easily do it with the others.

Answer 1

Trim is used to remove trailing or leading whitespace characters. How about String#split()?

String[] elements = "1 2 3 4".split(" ");

This would create an array of 4 elements, each containing a single number.
