Is there any way to make the constructor return a = = null object in Java?

I have a feeling that the answer is "no", but I think I'll ask just in case

Pseudo code:

Foo foo = new Foo();

if(foo != null){
    foo.useMe();
}else{
   System.out.println("foo Failed to initialize");
}

What do I need to do in foo to achieve this goal?

Solution

Normally, you only need to throw an exception for this case You can easily write your own exceptions, or just use throw new exception ("foo failed to initialize"); Grab that
