title: Java Beginner --Type of words in the code
body: <pre><code>public void sendMessage (View view) {
      Intent intent = new Intent (this, DisplayMessageActivity.class);
      EditText editText = (EditText) findViewById (R.id.edit_message);
  }
  </code></pre>
  
  <p>I am confused with the different of "Intent intent" type? Is it a classifier or variable or class? Why is the first letter of "Intent" is capitalize and the next one is not? also what is the type of "(Edit Text)", "findViewById" and (R.id.edit_message) ? </p>
  
  <p>The code is copied from developer android website.</p>
  
  <p>Thank you</p>
