Question

Given a String variable response that has already been declared, write some code that repeatedly reads a value from standard input into response until at last a Y or y or N or n has been entered. ASSUME the availability of a variable, stdin, that references a Scanner object associated with standard input.

Answer 1

Answer:

The following code is:

do     // set do while loop

{

response = stdin.next();    

}

while (response != "Y" || response != "y" || response != "N" || response != "n");

//  terminate do while loop

Explanation:

The following code starts with do while loop whose variables has already declared and then we assume the availability of the variable "stdin" which references the Scanner object and write some code to execute inside the do-while loop.
