title: How do you pass a string from one activity to another?
body: <p>I'm wondering how to pass and read a string that is in one activity from another activity. I have two activities. I'll call them Activity1 and Activity2. I have a string in Activity1 called <code>course</code>. I want to read that string in Activity2.</p>
  
  <p>I've tried doing this but the string came out empty. </p>
  
  <p><code>public class Activity2 extends Activity1 {</code></p>
  
  <p>I've seen people use the Intent function but I couldn't figure out how to use it.</p>
  
  <p>Any suggestions? Thanks!</p>
