Java Error: '____ has private access in ____'

[Josh Fedman]

Hello Everyone, I have been working on an assignment, and ran into this issue:

  symbol:   variable nextInt
  location: variable scanner of type Scanner
assignment5-16.java:29: error: newcard(int) has private access in MealCard
            student.newcard(amount);

Im getting this error everytime i try and call something from within the MealCard class.

the Mealcard class:

public class MealCard {
	
	int bal;
	
	public void Mealcard(){
		//placeholder
	}
	public void newcard(int amount) {
	if (amount >= 100) {
		bal = 100;
	} else {
		bal = amount;
		}
        System.out.println("Your balance is " + bal);
	}
	public void addpoints(int amount) {
	if (amount >= 1) {
		bal = bal + amount;
		System.out.println("your new balance is " + bal + " points");
	} else {
		System.out.println("Invalide Amount");
		}
	}
	public void purchase(int amount) {
	if ((bal-amount)<0) {
		System.out.println("You don't have enough points for this item");
	} else {
		bal = bal-amount;
		}
	}
    public int getBal() {
        return bal;
    }
}

and the main class:

class Assignment3_14 {

	public static void main(String[] args) {

	int amount, input, balance;
    MealCard student;
    
	Scanner scanner = new Scanner(System.in);
    student = new MealCard();
    
	System.out.println("Welcome, what do you want to do?");
	System.out.println("1. new user");
	System.out.println("2. purchase more points");
	System.out.println("3. use points");
    System.out.println("4. see balance");
	System.out.println("make your selection, then hit enter");
    input = scanner.nextInt();
	switch (input) {
    case 1: System.out.println("How many points do you want to begin with?");
            amount = scanner.nextInt;
            student.newcard(amount);
            break;
    case 2: System.out.println("How many points do you want do add?");
            amount = scanner.nextInt;
            student.addpoints(amount);
            break;
    case 3: System.out.println("How many points do you want do spend?");
            amount = scanner.nextInt;
            student.purchase(amount);
    case 4: balance = student.getBal();
            System.out.println("You have " + balance + "points in your account");
            break;
    default: System.out.println("Invalid selection");
			break;
        }
    }
}

The error is saying that the newcard method is private. The code you posted has the newcard method as public. Therefore the code and the error message do not match. Make sure you are working with the correct version of your code. Make sure you have saved your code. Make sure you compile the correct code. One way to make sure is to delete the .class file. This forces the compiler to compile the class again.

Ok, I did what you said, and it cleared up the original error i posted, but another error i was getting is still there.

  symbol:   variable nextInt
  location: variable scanner of type Scanner
assignment5-16.java:32: error: cannot find symbol
            amount = scanner.nextInt;

also, i forgot to mention that the MealCard class has been put into a user-defined package. i dont know if that makes a difference or not...

Notice how the error says it cannot find the "variable" nextInt!

SUPER EDIT: I AM DUMB.

my roommate walked in and figured it out in like 10 seconds. I was missing the parenthesis after .nextInt, so java thought it was a function.
Thanks for your help junky.

In this code snippet:

amount = scanner.nextInt;

you're using symbol nextInt as if it were a variable; it isn't, it's a method.

kind regards,

i have no idea why it thinks its a variable.

Yes you do if you just take a deep breath and think for a moment.

In the Scanner class nextInt is not a variable it is a .....? Because it is a .... it needs ....!
