Write the definition of a class Telephone . The class has no constructors, one instance variable of type String called number , and two static variables. One is of type int called quantity ; the other is of type double called total . Besides that, the class has one static method makeFullNumber . The method accepts two arguments, a String containing a telephone number and an int containing an area code. The method concatenates the two arguments in the following manner: First comes the area code, then a dash, then the telephone number. The method returns the resultant string.

How about asking a specific question and showing the code you have written. Otherwise we aren't going to do your homework for you.

Sorry ...first time post

the code i wrote :
==============
class Telephone{
String number ;
static int quantity;
static double total;
static String makeFullNumber(){
return quantity+"- "+n;
}
}
========
i don't how come it can't find the makeFullNumber ?

access modifiers...

Ok.
I think you forgot the public keyword. Maybe you should declare your method like this:

Writing "public " (Access- Modifiers ) , is not the error here .The class can be written with out it and it will be friendly by default (Can be Accessed inside the same package ) ??

don't go rambling about things you don't understand...

The fact that you end your statement with several question marks means you shouldn't have made it...

"you don't understand..." it is not good to say that for a one u don't know anything about him , just the user name . and the questions marks it was my mistake , and as u see also i put big wondering notations,

thanks

it's an instance variable, add private before you declare String
