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

No, String instantiation is handled implicitly by the compiler. Only the String and Array classes have this property.

String greeting = "Hello world!";
char[] helloArray = { 'h', 'e', 'l', 'l', 'o', '.' };

Autoboxing allows you to implicitly instantiate objects of primitive wrapper types, but that's also a special case handled by the compiler. You can't create your own classes with this ability.

Boolean b = false;
Integer i = 0;
Double pi = 3.1416;
