CRAPS-DUE

Create an applet where a circle will appear in a random location on the screen each time it is run.

Also in the lower right corner of the screen have it display the coordinates of the point.

Mouse Input

Count the number of times the user clicks and display this as drawString (clearing the previous time)

Mouse motion,

Create a method isPalindrome that takes in a String and determines if it is a palindrome (same forward as backward ie "dad")

HWJ8_Methods

Create a method dice that will return as an int a random roll of the dice. Remember Math.random()

casting,

random

Review:

Create a method that will find how much tax you need to pay. Tax is based on income:

public void findTaxesOwed(double income)

That will take in an income for a single filling person and spit out this info:

You need to pay $24,520 in taxes on the $110,000 you earned. That is a tax rate of 22.29%

Methods - parameters, saving classes

Saving new classes

• Create a scene with 3 people or animals and a beachball in the middle.
• Create a method rollTowards that takes in a parameter objectToRollTowards
• Have the ball roll towards that object
• In myFirstMethod, have the ball roll towards each object.
• Add a parameter numOfSpins that will determine the spin on the ball.

User Interaction

• Create a scene on the moon with a torus (under shapes).
• Create a method spinSize that will spin the torus and at the same time, make it bigger and then smaller.
• Create a method moveOnTopAnother that is going to take in a parameter another object called secondTorus and it will move that torus on top of the second torus;
• Save this class and import 3 more of them.

Functions, if/else, random

Realistic Roll

Review random numbers:

1. create a scene where every time space button a ball moves a random distance between 1-4 meters on a black screen
2. (TOGETHER) create a scene where every time space is pressed the ball moves either left, right, forward,up, down or backward a random distance between 1-4 meters.
3. Create a scene with a switch (controls-switch). Create a method flipSwitch that whenever the space bar is pressed it will flip from up to down. Create a function isUp that will return true if its up or false if its down.

Alice review:

• asSeenBy
• math functions

Article, take a look at

Think of these questions:

• How many hours a day (outside of class) that you spend on a computer?
• How much of that time is schoolwork?
• Do you think this software is necesssary?
• If you were a parent would you like these products?
• If you were an employer would you like these products?

Loops, Conditions

• Create a Japanese scene with a fandancer and 2 naginatas.
• Have the fandancer walk back and forth between them
• Have it repeat 2 times
• Try while loops in that scene have the woman walking between those naginatas. Have here go 1 meter at a time and then wave her fan each time. Repeat wlaking back and forth 3 full times.

Look at this site. In groups of 2, pick one article and give us a brief snyopsis.

Methods

• On your own, create a scene with a row boat.
• Make a method lookout that will cause the look guy to move his head back and forth
• Create a method row that will make the rower row the boat.
• Have the boat be rowed and have the lookout happen forever in the fog.
