Question

Hello this is an intro to CS course. The question is:

Using Java, write a program that asks the user to enter three numbers. Then passes these numbers to the following methods and prints out the numbers returned by these methods.

1. largest() – returns the largest of the three numbers
2. smallest() – returns the smallest of the three numbers
3. median() – returns the median of the three numbers

Example output is given below:

Enter three numbers

10

4

16

The largest is 16

The smallest is 4

The median is 10

Answer 1

Thanks for the question. Below is the code you will be needing. Let me know if you have any doubts or if you need anything to change. 

If you are satisfied with the solution, please leave a +ve feedback : ) Let me know for any help with any other questions.
