error when adding to pricelist

[oll3i]

in flowershop class

 Cennik c= Cennik.getInstance(); //cennik means pricelist
public void addFlower(String n,double c){
 
    c.setPricelist(n,c);
 
    }
 
 

in Pricelist class

public void setPricelist(String nazwaKwiat,double cena){       
    pricelist.put(nazwaKwiat,cena);   
}
 

why eclipse says cannot invoke c.setPricelist(String,double) on the prymitive type double

Parameter 'c' is a double, which is a primitive so it doesn't have any methods;
exactly what Eclipse was trying to tell you. I guess you wanted to type:

 
    // the member 'c' happens to be a PriceList
    this.c.setPricelist(n,c);

I'd suggest a better name for member variable 'c'; maybe 'priceList' would do?

kind regards,

Jos
