title: Is serialVersionUID = 1L better than generate serial version id?
body: <p>It may be sily question but still I am asking for an answer. I have written a program where I am generating serial version id using Eclipse IDE. But my project lead is insisting me to use only 1L instead of generating serial version id in case of Serializable interface. Please suggest me which is better. Is is better to use 1L or to generate serial version id while implementing Serializable interface. Is there any difference between the two ? Is there any performance impact ?</p>
  
  <p>Thnaks in advance.</p>
