getter, setter, and toString() methods in java?

in Programming Questions • 5 months ago

don't know if i can post this here, im using bluej...

So I need to create two classes: 1 class for a rectangle and 1 class for a circle with all necessary variables, constants, and methods.

And I'm stuck on :

public double calculatePerimeter ( double p){

p=2.0*(x+y);

return p;

}

(this is in my main class that controls the other classes)

and in my other class "Shape" I tried to system.out.print that and it doesn't work

I also have a string toString function...

not sure if its my syntax or something else

help?

that would be cleaner...

public double calculatePerimeter ( double p ) {
double Buffer;
Buffer=2.0*(x+y);
return Buffer;
}

maybe print / println doesn't take double?
try

........print ( mydouble2float ( calculatePerimeter (p1) ) );

mydouble2float you have to write ...

system.out.print
will not work need
System.out.print

and

string toString
should be
String toString

Java is case sensitive!

" im using bluej"
This is a forum about Processing, but since it is based on Java, and your question is of interest for people around, you are welcome.

public double calculatePerimeter ( double p){

p=2.0*(x+y);

return p;

}
Mmm, why do you pass a parameter if you ignore it?
As said above, something like:

public double calculatePerimeter() {

return 2.0 * (x + y);

}
would do the job.

" I tried to system.out.print that and it doesn't work"
If I get 1 € each time I see "it doesn't work", I would be rich! But alas, I don't get them, and we still don't know what "doesn't work".
Do you have a compilation error? A runtime error? Nothing at all?
In the first two cases, what error do you have?

Without these information and without code to scrutinize, it is hard to tell.
