I have got a problem with forEach loop

Looks like I miss something. The error is "illegal character", "; expected".. but I cannot see where :/

    IntStream.range(0, 100).forEach(i -> {
          String template = templates[i % templates.length];
          String buzzword = buzzwords[i % buzzwords.length];
          String title = String.format(template, buzzword);
          Course c = new Course(title, "http://www.example.com");
          Review review  = new Review((i % 5) + 1, String.format("Moar %s please!!!", buzzword));
          review.setReviewer(students.get(i % students.size()));
          c.addReview(review);
          bunchOfCourses.add(c);
    });

A few things would help:

  • Can you link to the video or challenge where this came up?
  • Can you post the whole error text? Often it comes with the line number, character number, stack trace.
  • Can you post the whole code in this file?

Yes, this is Java, not Javascript. Programming Java API in Spring. This is the course and video: https://teamtreehouse.com/library/populating-and-relationships

For some reason, this was IDE problem or something. I deleted part "forEach(i -> {" and wrote it again and everything works perfectly.
