In this class we define the main method in this method we define a string variable that is "s" and assign value to a variable that is "Java". Then we create a StringBuilder class object that is "buffer" and in object creation time we pass variable s as a parameter. Then we call the change function and print the function value that is "Java and HTML" In the change function, we pass the object of StringBuilder as a parameter. In this function, we use the append function in this function we pass value that is "and HTML". It is inbuilt function used to represent string value.
