Concept explainers
This type of method cannot access any non-static member variables in its own class.
- a. instance
- b. void
- c. static
- d. non-static
Static methods cannot be accessed by any non-static member variable within a class
Hence, the correct answer is option “C”.
Explanation of Solution
Static method:
Static is an access modifier which cannot be accessed and is applicable on block, variable, methods, and nested classes. Static keyword is added while declaring the block or variable or methods. A static member can be accessed before any objects of its class are created, and without even using the reference to any object.
Explanation for incorrect options:
a. Instance:
Instance variables are declared without the static keyword and are present outside any method declaration.
Hence, the option “A” is wrong.
b. Void:
It describes the return type of the method, where void means the method has no return value.
Hence, the option “B” is wrong.
d. Non-static:
Non-static variables can be accessed by any member variable.
Hence, the option “D” is wrong.

- Parent Class: Food Write a parent class called Food. A food is described by a name, the number of grams of sugar (as a whole number), and the number of grams of sodium (as a whole number). Core Class Components For the Food class, write: the complete class header the instance data variables a constructor that sets the instance data variables based on parameters getters and setters; use validity checking on the parameters where appropriate a toString method that returns a text representation of a Food object that includes all three characteristics of the food Class-Specific Method Write a method that calculates what percent of the daily recommended amount of sugar is contained in a food. The daily recommended amount might change, so the method takes in the daily allowance and then calculates the percentage. For example, let's say a food had 6 grams of sugar. If the daily allowance was 24 grams, the percent would be 0.25. For that same food, if the daily allowance was 36 grams, the…arrow_forwardIn a class with overloaded constructors, each version of the constructor must have a differentarrow_forwardTrue or False A static method can reference an instance variable.arrow_forward
