Do we create object when we make string without new operator?

Question

class Help {
    public static void main(String[] args) {
        String s1 = "hello";
        String s2 = "hello" + "world";
    }
}

Is s1 here an object reference variable, or did we create an object in the first statement?
- If answer is yes, then in the second statement how many objects will be created ?

In short since `"hello"` and `"world"` are *compilation time constants* which value is known at compilation time, compiler will do concatenation and compile `"hello"+"world"` as if it was written like `"helloworld"`. — Pshemo, Dec 22 '18 at 14:14

No. You will create a new String object always when you use new operator. If you create a String normally without new operator it will return an existing object from String pool if it is already existing, if its not it will create a new one
