Difference between String creation in class and in constructor

[dvsmas]

Can anyone please tell me if there is any difference in the following ways of a String creation.

class A{
String X;
A(){ X = new String("Hello"
}
}

class A{
String X=new String("Hello"
}

Which option is better?
Thanks in advance

Generally as a rule if both situations work identically, then the shorter code is more efficient. I guess that makes it "better"

Only the sequences are different. First the body is executed,then your constructor runs when you create an instance of your class A.

When you would have more than 1 constructor, there can be a difference, depending on which constructor you call.

There would also be a difference if your class would extend another class and you wanted to call super(...) [as it must be the first statement in the constructor].

Yes.Hologram is extremely correct.In fact I was looking for a good example to state this but could not find a good example for that.
