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 to be animated. “ScaleTransition(duration, node)” The argument “duration” denotes lasting time duration for animation. The “node” argument denotes the node to animate. setToX: The method “setToX” is used to specify scale factor along X axis. It takes value of X coordinate as argument. It denotes the ending scale factor of the node. setToY: The method “setToY” is used to specify scale factor along Y axis. It takes value of Y coordinate as argument. It denotes the ending scale factor of the node. Example: The example for “ScaleTransition” class and methods “setToX” and “setToY” 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); trns.setToX(3.0); trns.play(); 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.

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 to be animated.

“ScaleTransition(duration, node)”

The argument “duration” denotes lasting time duration for animation.

The “node” argument denotes the node to animate.

setToX:

The method “setToX” is used to specify scale factor along X axis.

It takes value of X coordinate as argument.

It denotes the ending scale factor of the node.

setToY:

The method “setToY” is used to specify scale factor along Y axis.

It takes value of Y coordinate as argument.

It denotes the ending scale factor of the node.

Example:

The example for “ScaleTransition” class and methods “setToX” and “setToY” 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);

trns.setToX(3.0);

trns.play();

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.

Observer pattern The PhoneModel class stores a phone number as a list of digits, and the Keypad class has this method: public void simulateKeyPresses(int numKeyPresses)(0 that allows the user to enter digits one at a time then save each digit in the list. The Screen wants to respond to each key being entered. Make the model notify the observers whenever a new digit is entered for the phone number. The first observer prints the newest digit out to the screen The second observer prints "Now dialing 12345678901.." out to the screen (where the number is the number the model has). Only the Screen class can print to the screen The model must be decoupled from the Other classes.

JAVA LANGUAGE Create an ArrayList, Name it YourRegNoandName that can hold Integers, and fill each slot with a different random value from 1-50. Display those values on the screen, and then prompt the user for an integer to search through the ArrayList, and if the item is present, say “FOUND”. It is not necessary to display anything if the value was not found. If the item is in the ArrayList multiple times, it's okay if the program prints the message more than once.
