Answer 1

Use set of characters([..]); it matches one of character listed.

String[] wordSplit = txtInput.split("[-\\s]")

Example:

class T {
    public static void main(String[] args) {
        String[] words = "hello world hello-world".split("[-\\s]");
        for (String word : words) {
            System.out.println(word);
        }
    }
}

output:

hello
world
hello
world

Answer 2

Use a character class:

String[] wordSplit = txtInput.split("[ -]");
