3.
High Low
Create a program that gets three numbers from a user. Write two methods: one called largest
which returns the value of the largest of its three double parameters, and one called smallest
which returns the value of the smallest of its three double parameters. The program should
then display both values with an appropriate message.
Transcribed Image Text:5. Data Validation
