Question

I have a question regarding java programming.

If I have this in a text file, " hey you <hello world> "

How can I get it so that it only extracts the words in between the "< > " ?

I am doing this with a stream and I know you can get it with the .map() function but I cannot figure out how to do it.

Please find below java code to do so:

import java.io.IOException;
import java.nio.file.Files;
import java.nio.file.Paths;
import java.util.stream.Stream;

public class Main {

    public static void main(String[] args) throws IOException {
        String filename = "/home/beenoo/HomeworkLib/text.txt";

        Stream<String> stringStream = Files.lines(Paths.get(filename))
                .map(input -> input.substring(input.indexOf("<") + 1, input.lastIndexOf(">")));
        stringStream.forEach(System.out::println);
    }
}
