I can't find out what the "@SuppressWarnings("serial")" actually does. I'm using eclipse and whenever I write any code the main class gets underlined and says:
The serializable class className does not declare a static final serialVersionUID field of type long
It says I need to add a serial version ID or suppress it. Why does it do this and is there any way I can stop it? Or is it perfectly normal? It never use to do it!
