title: How can I add many objects in array list?
body: <p>I am a junior android developer and I need some help in this part of my project</p>
  <p>I going to add a group of universities like this</p>
  <p><img src="https://i.stack.imgur.com/QFS2I.png" alt="description here" /></p>
  <p>and in every university there are many courses and each course contains many files in it (past papers, past quizzes ….etc.) from firebase storage so how I can add the courses to every university (Name of the course, code of the course)</p>
  <pre><code>public class course {
  
      String courseName;
      String courseCode;
  
      public course(String courseName, String courseCode) {
          this.courseName = courseName;
          this.courseCode = courseCode;
      }
  }
  </code></pre>
  <p>using recycler View? by adding Array List for every university? and how to add theses courses like 100 courses for every university.</p>
