illegal start of expression

[freddiecool]

Hi can anyone help me i get an illegal start of expression public static void main everytime i try to compile.My code is below.
Thanks...

public static void main (String []args){
PrylDialog pd=new PrylDialog();
System.out.println("Welcome!!!!! ");
int option=0;
do{
option=pd.kommando();
switch(option){
case 1:pd.skapaPerson();
break;
case 2: pd.skapaPryl();
break;
case 3: pd.visaAlla();
break;
case 4: pd.visaRikast();
break;
case 5: pd.visaVissPerson();
break;
case 6: pd.börskrasch();
break;
case 7: System.out.println("That's all folks... ");
}
}
while (option!=7);
}
}

Hi freddiecool and welcome to DaniWeb,

Not sure if this is your problem, but your variables should be initialised as private. ie:

private pryDialog pd = new pryDialog();
private int option = 0;

[javaAddict]

At which line do you get the Error?

Hi freddiecool and welcome to DaniWeb,

private pryDialog pd = new pryDialog();
private int option = 0;

No, those are local variables inside the method. They do not have access modifiers like "private".

We need to see what comes directly before the method. That error normally occurrs because you've done something wrong before that, such as not closing a previous method, or forgetting a semicolon on the previous line, etc.

[uonsin]

you might want to check if the error is in pryDialog() because to me, your code should not give you an error

That error is a compiler error, and as I have said, it is normally triggered by what came before. I.e. the previous method does not have a closing brace (so you then are effectively trying to declare a method within a method) or the last statement is missing the semicolon (which then means that the method declaration is effectively part of the previous statement) are the two main causes of this.

Oops ... good point. :$

This is my whole code, if anyone could spot the problem.Im not sure which line it is but it is an illegal start of expresion "public static void main(String []args){" at the end of the code.

your

void skapaPrylar(){

method is not closed. add another

}

above the

public static void main ....

By using code tags.

[freddiecool]

Thanks that helped, i must have removed by mistake when i tried to fix this problem.Why cant the compiler find "prylar" but it can find "Person p: personer"?

PrylDialog.java:38: cannot find symbol
symbol : variable prylar
location: class PrylDialog
for (Prylar pro : prylar)
^
PrylDialog.java:104: cannot find symbol
symbol : method skapaPryl()
location: class PrylDialog
case 2: pd.skapaPryl();
^
PrylDialog.java:106: cannot find symbol
symbol : method visaAlla()
location: class PrylDialog
case 3: pd.visaAlla();

[masijade]

Prylar getPrylar(String prylr){
      for (Prylar pro : prylar)

void skapaPrylar(){

symbol : method skapaPryl()

Notice the spelling.

[freddiecool]

I still cant find prylar. Do i have to declare prylar somewhere?Maybe innitiate an ArrayList like i did for (PERSON : personer)?

PrylDialog.java:38: cannot find symbol
symbol : variable prylar
location: class PrylDialog
for (Prylar pro : prylar)
^

[Ezzaral]

Yes, I don't see that you have declared "prylar" anywhere, yet you are using it as a class-level variable.

[freddiecool]

Im very new, im not quite sure where to declare it.I have another class by the name" class Prylar".I tried to make an ArrayList like i did for (PERSON:personer) but i gor thge following error.

PrylDialog.java:8: cannot find symbol
symbol : class Arraylist
location: class PrylDialog
Arraylist prylar= new Arraylist();
^
PrylDialog.java:8: cannot find symbol
symbol : class Arraylist
location: class PrylDialog
Arraylist prylar= new Arraylist();
^
c:\oop\html\up2\Smycke.java:1: Smycke is not abstract and does not override abstract method getVarde() in Prylar
class Smycke extends Prylar{
^
3 errors

[Ezzaral]

Check your spelling. The correct class is "ArrayList".

The last error means that you've extended a class that has an abstract method in it, which requires you to implement that method, but you have not written that method in your class.
