Create object with Switch Statement: Cannot make a static reference to the non-static method?

Question

I have trying to create an object based on the type using switch statement. However I am getting this error on the method in main method:

Cannot make a static reference to the non-static method CreateCoffee(CoffeeFactory.Type) from the type CoffeeFactory

public Coffee CreateCoffee(Type t ) {
    ingred = null;

    switch (t) {
     case LONG_BLACK:  
         ingred.add(Ingredient.ESPRESSO);
         return new Coffee(ingred, t);
     case FLAT_WHITE: 
         ingred.add(Ingredient.MILK);
         return new Coffee(ingred, t);
     case MOCHA: 
         ingred.add(Ingredient.CHOCOLATE);
         return new Coffee(ingred, t);

    default: return null;
    }


}

public static void main(String[] args) {
    CreateCoffee(Type.MOCHA);
}

what am i doing wrong, is it the return new Coffee() statement in each switch case?

You need to make the CreateCoffee method static as it is referenced directly from the main method which is static.

static enables you to call a method without creating any object.so if you're calling a static method in this case main then you can call methods with the help of objects or you can call other static methods.
