title: Can a Java Bean contain one or more parameterized constructors?
body: <p>I'm new to java and I have a question. According to my knowledge, Java beans have the following properties.</p>
  
  <ul>
  <li>They should be serializable, i.e. they should implement the serialization interface.</li>
  <li>They should have a no-argument constructor.</li>
  </ul>
  
  <p>What is the meaning of <strong>have a no-argument constructor</strong>? Does it mean that there can only be a no-argument constructor? Can't they have parameterized constructors? Does that mean that bean classes cannot have constructor overloading?</p>
