Question

I have a syntax question.

I know that object of a class can be created as:

MyClass classname = new MyClass();

but can is it ok if a do the following:

MyClass classname;
//.....some lines of code
classname = new MyClass();

Yes you can instantiate the object on a different line than the type declaration, however it is only useful when you want to instantiate the object in a different scope:

Object o;
try {
     o = new Thing();
} catch(Exception e) {
}
o.toString();
