Java '.class' expected, simple but im not seeing it
I'm working on a project right now and need to list 3 parellel arrays. This is what my compiler error looks like.
[quote] '.class' expected
')' expected [/quote]
It's really bugging be, so here are the two methods.
This is the code that my info is being sent to. This method is in a class named ListPets
publicvoid listPets(String[] name,double[] price,int[] quanity)
{
for(int i = 0; i<name.length; i++)
{
output+="\n"+name[i]+""+price[i]+" "+quanity[i];
}
}
this is what is being sent to it
This code is in a class called MainGui
I also have this little bit at the top.
ListPets panList =new ListPets();
publicvoid actionPerformed(ActionEvent ae)
{
panList.listPets(petname[], petprice[], petquanity[]);
}
I feel like im over looking somthing, but i cant find it. Any help on this would be nice, thanks,>

You are trying to call a method in the line of code above. So you should only include the variable names, like thispanList.listPets(petname, petprice, petquanity);
Some feedback on your design: It looks like you have (at least) 3 arrays whose contents relate to each other. That is, petname[2] is a pet type's name, petprice[2] is the same pet type's price and petquantity[2] is the same pet type's quantity. In Java, you should not use "parallel arrays" to associate the contents of arrays. Instead, you should have a class - that's the whole idea of object oriented programming.

You are welcome. No, I did not mean a separate class for each variable. I meant a class that holds the related variables, for example PetItem. It sounds like you have an inventory of pet stuff so may be each 'thing' in the inventory is a PetItem. The PetItem has a name, price and quantity - maybe more.
