Generate string from array in Java

Convert the array into String using Collectors.joining() method of the stream package:

import java.util.stream.Collectors;
import java.util.stream.Stream;

class GenerateStringFromArray {
  public static void main(String[] args) {

    String[] values = {"Bookmarks.dev -", "Bookmarks", "and", "code snippets", "manager"};

    String text = Stream.of(values)
        .map(Object::toString) // in this case you can remove the map, but useful for complexer objects
        .collect(Collectors.joining(" "));

    System.out.println(text);
  }
}

Result

"Bookmarks.dev - Bookmarks and code snippets manager"
