How java create objects implicitly? Like in case of String class

Question

I can\'t understand how an object is created implicitly.

Example:

String s = \"implicit instantiation\";

Can I make my own class w

Answer 1

For every instance of an object you need a Constructor and a constructor its a a special method for construct and initialize methods. Example:

String s;  // Is not initialized and it's nos constructed.

So how do you construct a new object in java? Easy with the new operator you create a New Object!

s = new String("qwe"); // New object constructed

But here is something that a lot of newbies get confussed. Why i can do this:

String s= "asdfasd;" 

Because String is a special case in Java and you don't need to add a new operator like all the primitive variables that are classes. Example:

Integer i = 3; 
Double d = 3.3d;

and So on.
