title: Importing a user defined class in java
body: <p>The below is a test code where I am getting an error <code>Pizza order = new Pizza();</code> I believe that I didn't import Pizza.class to Pizzaorder.class file. Can anybody help me in fixing this error.</p>
  
  <p>Code follows.</p>
  
  <p>Pizza.java</p>
