This question already has an answer here:
Hi there I have one of two problems. when I try to access the function below ,which is in an object, from a function in the main class called erase(int[], int[]), I get cannot find symbol, can someone explain how I achieve what I intended.
Function in object called cards: public void setCard(int position){ System.out.println(" Value before erase: " + this.pack[position] + " Position value: " + position); this.pack[position] = 0; System.out.println(" Value after erase: " + this.pack[position] + " Position value: " + position); }

alternatively if I invoke the cards from outside of the main class i get the second error in the title
