In order to write this or any other Java program of substance, you will need to
know
how to use the
Java Platform, Standard Edition API Specification as well as the documentation for the
Guzdial-Ericson Multimedia Class Library .
You may find other useful hints in my online tutorials and slides for this
course as well as in the YouTube video lectures for this course.
Testing Your Programs
You can compile and execute your program by following the instructions given
at
Java OOP: The Guzdial-Ericson
Multimedia Class Library .
Program Specifications
Program 1
Discussion
The following is a non-exhaustive list of concepts that you need to
understand along with knowledge and skills that youneed to possess in order to successfully write this program and/or understand
the given solution in
Prob01.java . Some of these items
are general in nature and some are specific to the use of Ericson's multimedialibrary.
- How to design and implement an algorithm that will transform
Prob01.jpg into the image
shown in
Figure 1 .
- How to incorporate and use an
external class library in addition to the standard Java class library.
- The
general syntax for a Java application
(not a
Java applet).
- How to
write ,
compile, and execute a
Java application that uses the Guzdial-Ericson Multimedia Class Library.
- How to use the standard
print and
println methods of the
System class to display text on
the command-line screen.
- The effect of
overridden versions of the
toString method on the
print and
println methods
- Knowledge of the need for and use of
import directives .
- How to
define and
instantiate an object of a new class
named
Prob01Runner .
- Knowledge of the difference between
local variables and
instance variables .
- How to declare local
reference variables of a given type.
- How to save the
Prob01Runner object's reference in a
reference variable of type
Prob01Runner named
obj .
-
How to call the
run method,
(which
controls the major behavior of the program) , on the
Prob01Runner object's reference.
- How to use
private ,
public ,
protected , and
package-private access modifiers.
- How to declare and use
reference variables versus
primitive variables .
- How to select the appropriate
overloaded
constructors in order to i
nstantiate objects of Ericson's
World ,
Turtle , and
Picture classes.
- How to define a
constructor for a class.
- How to write
accessor methods in your new class
definition that return references to
Turtle and
World objects.
- How and why to call
accessor methods on objects.
- How to instantiate
anonymous objects .
- How to
replace the default white
Picture object encapsulated in a
World object with a new and different
Picture object encapsulating the contents of a local image file.
- How to call a method on a
Picture object to
write
text onto the
Picture object.
- How to
call a variety of methods on objects of
the
Turtle class to cause the
Turtle objects in
your world to do things, such as move forward, change their colors, etc.
- How pictures are composed of images.
- How images are composed of pixels.
- How pixels are composed of red, green, and blue color values.
- How objects can be used to represent pictures, images, and pixels.
- How methods can be called on those objects to manipulate the red, green,
and blue color values.

In economics, a perfect market refers to a theoretical construct where all participants have perfect information, goods are homogenous, there are no barriers to entry or exit, and prices are determined solely by supply and demand. It's an idealized model used for analysis,

What is different between quantity demand and demand?
Quantity demanded refers to the specific amount of a good or service that consumers are willing and able to purchase at a give price and within a specific time period. Demand, on the other hand, is a broader concept that encompasses the entire relationship between price and quantity demanded

how do you save a country economic situation when it's falling apart
what is the difference between economic growth and development
Economic growth as an increase in the production and consumption of goods and services within an economy.but
Economic development as a broader concept that encompasses not only economic growth but also social & human well being.

sir...I just want to ask one question... Define the term contract curve? if you are free please help me to find this answer 🙏

it is a curve that we get after connecting the pareto optimal combinations of two consumers after their mutually beneficial trade offs

thank you so much 👍 sir

In economics, the contract curve refers to the set of points in an Edgeworth box diagram where both parties involved in a trade cannot be made better off without making one of them worse off. It represents the Pareto efficient allocations of goods between two individuals or entities, where neither p
