Write a method so that the main() code below can be replaced by the simpler code that calls method mphAndMinutesToMiles(). Origi
defon

ANSWER

The JAVA program after simplification is as below.

import java.util.Scanner;

public class CalcMiles {

   

   // variables declaration

   static double milesPerHour;

   static double minutesTraveled;      

   static double hoursTraveled;

   static double milesTraveled;

   

   // method declared static

   public static void mphAndMinutesToMiles(double speed, double mins)

   {

       // computations to calculate distance travelled

       hoursTraveled = mins / 60.0;

       milesTraveled = hoursTraveled * speed;

       

       // result displayed on the screen  

     System.out.println("Miles: " + milesTraveled);

   }

   

   // Scanner object created inside main()

   // user input taken inside main()

   public static void main(String [] args)

   {

       Scanner scnr = new Scanner(System.in);

       System.out.println("Enter miles travelled per hour ");

       milesPerHour = scnr.nextDouble();

       System.out.println("Enter minutes required to travel ");

       minutesTraveled = scnr.nextDouble();

       

       mphAndMinutesToMiles(milesPerHour, minutesTraveled);

       

   }

}

OUTPUT

Enter miles travelled per hour  

2.3

Enter minutes required to travel  

1234

Miles: 47.30333333333333

EXPLANATION

The program is simplified as explained below.

1. User input is taken using the object of Scanner class.

2. This object of Scanner class can only be created inside main() method hence, user input can only be taken inside main().

3. The code to calculate the result is separated in another method, mphAndMinutesToMiles(). This method is declared with return type void since no value is returned.

4. After user input is taken in main() for miles travelled per hour and minutes required to travel, these values are passed as parameters to the mphAndMinutesToMiles() method.

5. These parameters are used in calculation part. The total miles travelled in total hours (obtained from minutes), is calculated. The code to display the result is added to this method.

6. Inside the main method, only the code to create Scanner object, code to take user input for two variables and code to call the mphAndMinutesToMiles() is included.

7. The variables are declared as static and declared at class level.

8. No variable is declared inside any of the two methods.

Given that Jamie worked 50 hours (Hours = 50) last week and earns $10.00 an hour (Rate = 10), how much did Jamie earn last week,
quester [9]

Answer:

<em>Jamie earned (Total pay)  $500.</em>

<em></em>

Explanation:

We are given the following code:

<em>If (Rate >=10) OR (Hours <=40) Then </em>

<em>    TotalPay = Hours * Rate </em>

<em>Else </em>

<em>    TotalPay = (Hours * Rate)+(Hours–40)*Rate*1.5 </em>

<em>End If</em>

<em />

Let us understand the code line by line:

The first line contains an if statement with 2 conditions:

i.e. 1st condition:

The rate is greater than or equal to 10

2nd condition:

Number of hours are lesser than or equal to 40.

There is OR between the two condition i.e. the statement next to if() statement will get executed if any one of them becomes true and else part will not be executed.

The next statement is:

TotalPay = Hours * Rate

It calculates the pay if any of the two conditions written earlier becomes true.

Next statement is else statement:

It will get executed given that the above if() statement becomes false.

Now, we are given that Jamie worked 50 hours last week and earns $10.00 an hour:

i.e.

Hours = 50

Rate = 10

Now, let get to the code execution.

The first condition is true i.e. Rate >= 10 (because Rate is 10 here)

So, the following statement will be used to calculate the Total pay:

TotalPay = Hours * Rate

and else part will not be executed.

TotalPay = 50 * 10  =<em> $500  </em>

<em></em>

<em>Jamie earned (Total pay)  $500.</em>
