Accessing enum variables/methods

enum ChineseMenu {

    SOUP_CHICKEN(22), SOUP_VEG(32),

    NOODLES_NONVEG(23), NOODLES_VEG(55),

    RICE_NONVEG(43), RICE_VEG(66);

    private int value;

    ChineseMenu(int price) {
        this.value = price;
    }

    public int getCost() {
        return value;
    }
}




class ChineseDemo {

    public static void main(String[] args) {
        ChineseMenu[] chineseArray = ChineseMenu.values();
        for (ChineseMenu menu : chineseArray) {
            System.out.println("The price of " + menu + " is ");//i want to add the price value
        }

    }
}

In the above code i want to add the prices value after "is". I even tried declaring a method and then calling the same. But it gives an error that static type cannot refer to non static variables

Judging by the above line from your question and the fact that your print statement says The price of menu is, it looks like you want to print the total cost of the Chinese menu :

You can create a variable called total that holds the total price :

public static void main(String[] args) {
        ChineseMenu[] chineseArray = ChineseMenu.values();
        int total = 0;
        for (ChineseMenu menu : chineseArray) {
            total+=menu.getCost();

        }
        System.out.println("The price of Chinese menu is "+total);

}

How about this one:

System.out.println("The price of " + menu + " is " + menu.getCost());
