Java equivalent of Python's str.strip().split()?

Question

If I had the following

str1 = "   Just a test   "
str2 = "                "

l1 = str1.strip().split()
l2 = str2.strip().split()

I'd get

l1 = ["Just", "a", "test"]
l2 = []

How would I accomplish this in Java?

Answer 1

You could use String.trim() and String.split(String) (which takes a regular expression). Something like,

String str1 = "   Just a test   ";
String str2 = "                ";
String[] l1 = str1.trim().split("\\s+");
String[] l2 = str2.trim().split("\\s+");
System.out.println(Arrays.toString(l1));
System.out.println(Arrays.toString(l2));

Outputs (the requested)

[Just, a, test]
[]
