Question
Chapter 14, Problem 8SA
Program Plan Intro
ScaleTransition class:
- The “ScaleTransition” class makes a node larger or smaller over time.
- The constructors of class define different types of operations.
- The constructors in “ScaleTransition” class includes:
- ScaleTransition():
- It creates a “ScaleTransition” object that is empty.
- The “setDuration” method establishes animation’s duration.
- The “setNode” method specifies node that is to be animated.
- “ScaleTransition(duration)”
- The argument “duration” denotes lasting time duration for animation.
- The “setNode” method specifies node that is to be animated.
- “ScaleTransition(duration, node)”
- The argument “duration” denotes lasting time duration for animation.
- The “node” argument denotes the node to animate.
- ScaleTransition():
setFromX:
- The method “setFromX” is used to specify scale factor along X axis.
- It takes value of X coordinate as argument.
- It denotes the starting scale factor of the node.
setFromY:
- The method “setFromY” is used to specify scale factor along Y axis.
- It takes value of Y coordinate as argument.
- It denotes the starting scale factor of the node.
Example:
The example for “ScaleTransition” class and methods “setFromX” and “setFromY” is given below:
Circle cir = new Circle(0, 40, 20);
ScaleTransition trns = new ScaleTransition(new Duration(5000), cir)
trns.setFromX(1.0);
trns.setFromY(1.0);
trns.setToX(3.0);
Here, “cir” denotes an object of “Circle” class. The given code generates a circle with particular dimensions. The animation’s duration is 5 seconds. The circle is been displayed with scale factor of 1 initially and it increases to a scale factor of 3.

Method: addOneMinute()
Description: This method adds one minute to the current time.
Method Signature: void addOneMinute()
Parameters: This method does not take any parameters.
Return Value: This method does not return anything.
Instructions:
Check the value of getMinute(). If it is between 0 and 58 inclusive, add 1 to it and call setMinute() with the new value.
If getMinute() is 59, set minutes to 0 by calling setMinute(0), and then call addOneHour() to add one hour to the time.
Note: You may change things around in your program, but for now please make this method work with the existing method signatures.

Road Trip
Programming challenge description:
You've decided to make a road trip across the country in a straight line. You have chosen the direction you'd like to travel and made a list of cities in that direction that have gas stations to stop at and fill up your tank. To make sure that this route is viable, you need to know the distances between the adjacent cities in order to be able to travel this distance on a single tank of gasoline, (No one likes running out of gas.) but you only know distances to each city from your starting point.
Input:
Your program should read lines from standard input. Each line contains the list of cities and distances to them, comma delimited, from the starting point of your trip. You start your trip at point 0. The cities with their distances are separated by semicolon.
Output:
Print out the distance from the starting point to the nearest city, and the distances between two nearest cities separated by comma, in order they appear on the route.
