How to iterate nested lists with lambda streams?

Question

I\'m trying to refactor the following code to lambda expressions with `stream, especially the nested foreach loops:

public static Result match (Response rsp) {
          


        

Answer 1

You can iterate nested loops like below

allAssessmentsForJob.getBody().stream().forEach(assessment -> {
        jobAssessments.stream().forEach(jobAssessment -> {
            if (assessment.getId() == jobAssessment.getAssessmentId()) {
                jobAssessment.setAssessment(assessment);
            }
        });
    });
