Program Plan Intro

Fuel efficiency of a multi-leg journey

Program Plan:

Declare the “MPG” function.

Assign the values to the variables.

Iterate the “for” loop until it reaches the last line in the text file.

Set the value.

Check “leg” is not equal to newline.

In “try” block,

Split the odometer reading and amount of gas from the user input and assign it into the separate variables.

Increment the “count” value.

Calculate the distance traveled, total distance.

Calculate the MPG for leg.

Set the new odometer reading.

Display the leg.

Add values to trip total.

Break the function.

In exception block, break the function.

Return the value to the main function.

Declare a main function. Inside the main function,

Get the input file name from the user.

Open the file.

Get the starting odometer reading from the user.

Java Graphics (Bonus In this lab, we'll be practicing what we learned about GUIs, and Mouse events. You will need to implement the following: A GUI with a drawing panel. We can click in this panel, and you will capture those clicks as a Point (see java.awt.Point) in a PointCollection class (you need to build this). The points need to be represented by circles. Below the drawing panel, you will need 5 buttons: O о о ○ An input button to register your mouse to the drawing panel. A show button to paint the points in your collection on the drawing panel. A button to shift all the points to the left by 50 pixels. The x position of the points is not allowed to go below zero. Another button to shift all the points to the right 50 pixels. " The x position of the points cannot go further than the You can implement this GUI in any way you choose. I suggest using the BorderLayout for a panel containing the buttons, and a GridLayout to hold the drawing panel and button panels. Regardless of how…
