title: How do I add an integer input for my program in java swing?
body: <p>So I have a program in swing where I am supposed to calculate the cost of staying in a hotel room for "x" amount of weeks.</p>
  
  <p>I want to be able to have the user input "x" but I am not sure what code I would use.  Also Here is my code so far.</p>
  
  <pre><code>public class Hotel extends JFrame
  {
      int room1 = 0;
      int room2 = 0;
      int weeks;
      int boat = 0;

      JLabel l, l1;
      JTextField t, t1;
      JButton b;
      JCheckBox b1, b2, b3;
  
      Hotel()
      {
          setTitle("Hotel Room Selection");
          setSize(800, 800);
