14) Write a while loop that uses the Scanner object scnr and loops if the next input to be read is a number of type double. (You do not need to provide the declaration of the Scanner, nor the entire loop body, just the loop statement, the delimiters that bound the body and a comment of some sort within that body.)

24) Write valid Java code to declare a variable of type int and assign an initial value of the integer portion of a variable of type float to it. You may select your own variable names, but be polite.

27) Write a valid Java code segment to create an instance of a Scanner that reads from the string variable, tests for a long as the next token in that stream. Be sure you include any intermediate operations that must occur between those two operations.
