Difference in declaration of Strings with or without 'new' keyword in Java

In this video lecture we will learn the difference between declaration of String with "new" keyword and without "new" keyword.

String s = "Hello";
String s = new String ("Hello");

We have discussed only the theory part here in which I have made some diagram or memory representation but If you want to see the java program then watch my video in which I have used methods to differentiate between them, the link of which is below.
