• The third method takes one integer followed by a variable number of integers ...read more

The program will result in a StackOverflowError due to infinite recursion.

• The 'floating' method is recursively calling itself without a base case to stop the recursion.

• Each recursive call multiplies the input parameter by the result of the recursive call with a decremented parameter.

• This will continue indefinitely until the stack overflows and an error is thrown.

Front controller is a design pattern used in Spring MVC to handle incoming requests and route them to appropriate handlers.

• Front controller acts as a central point of control for handling requests in Spring MVC.

• It receives all incoming requests and delegates them to appropriate handlers called controllers.

• Front controller provides a consistent way to handle requests and perform common tasks like authentication, logging, etc.

• In Spring MVC, the DispatcherServlet acts as the fro...read more

The output of the code is 9.

• The code initializes i as 0 and j as 10.

• Inside the do-while loop, i is incremented by 1 and j is decremented by 1.

• The loop continues until i becomes greater than or equal to j.

• Since i is incremented before the comparison and j is decremented before the comparison, the loop runs 9 times.

• Therefore, the output is 9.

An annotation for controller in software engineering.

• The annotation for controller is used to define the class as a controller in a software application.

• Additional attributes can be used to further customize the mapping, such as specifying request parameters or headers

• Example: @RequestMapping(value = ...read more

The 'final' keyword in Java is used to declare constants, prevent method overriding, and ensure thread safety.

• Final variables cannot be reassigned once initialized

• Final methods cannot be overridden by subclasses

• Final classes cannot be extended by other classes

• Final parameters ensure that they cannot be modified within a method

• Final fields can be used to achieve thread safety
