Hi, Im trying to get a head start on my Uni course starting next semester.
Here is my code with the problem line highlighted. I wrote another program
with the same snippet of code but it didnt pick it up as an error. My email
address is funtybugwana@icqmail.com
Thanks Mark
This is the compiler output:
--------------------------- Compiler Output ---------------------------
C4Q3.java:76: Undefined variable or class name: output
output.append (callOutput + calldurationOutput + callCostOutput +
totalcallCostOutput + "\n");
^
This is my code:
import java.awt.*;
import BreezyGUI.*;
public class C4Q3 extends GBFrame{
//format the header of the table. number represent number of letters
plus spaces.
String header = Format.justify('l',"Call no.",12) +
Format.justify('c',"Call Duration", 18) +
Format.justify('r',"Call Cost", 13) +
Format.justify('r',"Total Call Cost",20) + "\n";
Label TeleCallCostLabel = addLabel("TELECALLCOST INTERFACE", 1,1,1,1);
Label MinutesLabel = addLabel ("Enter No. Of Minutes",2,1,1,1);
DoubleField MinutesField = addDoubleField (0,2,2,1,1);
TextArea outputArea = addTextArea(header,4,1,6,4);
Button EnterButton = addButton ("Enter",8,2,1,1);
Button ResetButton = addButton ("Reset All",9,2,1,1);
String callOutput, calldurationOutput, callCostOutput,
totalcallCostOutput;
double Minutes = 0; //Initialise Variables
double Dollars = 0;
double total = 0;
int call = 0;
public void buttonClicked (Button buttonObj){
Minutes = MinutesField.getNumber();
if (buttonObj == ResetButton)
/*Call resetGlobalVariable Method
*If Reset Button is pushed */
resetGlobalVariables();
if (buttonObj == EnterButton)
call = ++call;
if(Minutes <= 0)
messageBox //Configure Printout in Message Box
("Sorry, We cannot Give Refunds!" + "\n" +
"Enter a Positive Number to Continue" + "\n");
if (Minutes <= 2 && Minutes > 0){
Dollars = 1.15;
total = Dollars + total;
}
else{
Dollars=((Minutes - 2.0) * 0.50) + 1.15 ;
total = Dollars + total;
}
//Format the output data
callOutput = Format.justify('l', call, 12);
calldurationOutput = Format.justify('c', Minutes ,18, 2);
callCostOutput = Format.justify('r', Dollars, 13, 2);
totalcallCostOutput = Format.justify('r', total, 20, 2);
// Output data
output.append (callOutput + calldurationOutput + callCostOutput +
totalcallCostOutput + "\n"); **** THIS IS THE PROBLEM LINE****
}
/**********************************************************************/
private void resetGlobalVariables()
{
//Global variables reset here
Minutes = 0;
Dollars = 0;
MinutesField.setNumber (0);
}
/*********************************************************************/
public static void main (String [] args)
{
Frame frm = new C4Q3();
frm.setSize (600, 600);
frm.setVisible (true);
}

If you are going to use a variable, you ned to declare it. Did you actually
mean
System.out.println(/* whatever */);
?
