Write the definition of a method named add that receives a reference to a Scanner object associated with a stream of input consisting of integers only. The method reads all the integers remaining to be read from the stream and returns their sum. So if the input were 3 51 204 17 1040, the returned value would be 1315. The method must not use a loop of any kind (for, while, do-while) to accomplish its job.

public int add (Scanner input) {

int sum = input. nextInt ();

if (input. hasNextInt ()) {

sum=sum+add (input);

}

return sum;

}

Explanation:

Define a method named add that receives a reference to a Scanner object. Take sum as input from the user. Use if statement to check whether it has an integer. Add that integer to sum variable. Return the sum variable.
