Get substring between 3rd colon and 4th colon

Question

I have strings in the below pattern:

ab:ab:ab:1:ab
ac:ac:ac:2:ac
ad:ad:ad:3:ad

I have to extract the string between the 3rd colon and the 4th colon.

For the above example strings, the results would be "1", "2" and "3".

What is a short way in Java using string functions to extract it?

Answer 1

You can just split by ":" and get the fourth element:

something like:

Stream.of("ab:ab:ab:1:ab", "ac:ac:ac:2:ac", "ad:ad:ad:3:ad")
      .map(s -> s.split(":")[3])
      .forEach(System.out::println);

Output:

1
2
3
