Consider the following code,string s=new String(); will create an instance of string with

The code string s = new String(); will create an instance of a string with no characters in it, essentially an empty string.

Here's the step-by-step explanation:

1. string s: This declares a variable s of type string. In other words, s is a variable that will hold a string.

2. new String(): This is a constructor that creates a new instance of the String class. The parentheses () indicate that this is a method call. In this case, it's calling the String constructor method with no arguments.

3. =: This is the assignment operator. It assigns the value on its right (the new String instance) to the variable on its left (s).

4. ;: This is a semicolon that marks the end of the statement.

So, after this line of code is executed, s will be an empty string.
