Chapter 3.3, Problem 22SCP

a.

Explanation of Solution

Given statement:

  //Create Scanner object

    Scanner console= new Scanner(System.in) ;

    //Prompt the user to enter the value

    System.out.print("How much money do you have? ");

    //Get the double value form the user

    double money=console.nextDouble();

When entering the value “34.50”:

• The user can get the keyboard input using “Scanner” object.
• The function “next()” is used to get the input from the user.
• The value of double type can be entered from the user using the method “nextDouble()”.
• This method can return the double of the scanned keyboard input...

    double money=console.nextDouble();

When entering the value “6”:

• The user can get the keyboard input using “Scanner” object.
• The function “next()” is used to get the input from the user.
• The method “nextDouble()” is used to return the double of the scanned keyboard input.
• If the user enters the value “6”, the method “nextDoublle()” accepts that value and assign the double of the input “6”,which means “6...
