Check if String equals class name

Question

In my main method, my first argument is a class PersonInfo lets say. How do I do this?

 if(argument.equals(PersonInfo) {
  //invoke method A
 }

  if(argument.equals(MyInfo) {
  //invoke method B
 }

Since arguments in main method are Strings, how do I check if these Strings equal my class name?

PersonInfo.class.getSimpleName() is what you are looking for, and do it otherway so that you won't have to handle null check

Perfect. However, what happens when I do it the other way, and the argument the user passes is null? Do I need to do a null check there? – rickygrimes Jul 30 '14 at 20:42

You want to get the name of the class then compare it to your argument.

if(argument.equals(PersonInfo.class.getSimpleName()))
{
  //invoke method A
}

if(argument.equals(MyInfo.class.getSimpleName()))
{
  //invoke method B
}
