Question

In java, create a method called getString that will read in Strings as in:

Please enter the name of the traveler: david
Please enter the destination: rockey mountains
Please enter the car model: honda

• The method is sent: "name of the traveler" or "name of the car" or "destination"
• The method reads in the String
• The method returns the String that was read in

In the main:
String name = getString("the name of the traveler");

Write the method called getString:



3) Create a method called getDouble that will read in doubles as in:

Please enter the MPG for this car: 14.6
Please enter the miles to destination: 1200

Please enter the cost per gallon: 3.62

• The method is sent: "MPG for this car" OR "miles to destination" OR "cost per gallon"
• The method reads in the double
• If the number is less than or equal to zero, the method asks again and again until a positive number is entered
• The method returns the double that was read in

In the main:
String name = getDouble("the miles per gallon");

Write the method called getDouble:



4) Write a main method to finish the class to include calling the methods that will create the following in the terminal window:
