What is an accessor method in Java example?
In Java, accessor methods return the value of a private variable. This gives other classes access to that value stored in that variable. without having direct access to the variable itself. Accessor methods take no parameters and have a return type that matches the type of the variable they are accessing.
Which method is called as accessor method in Java?

What is the purpose of an accessor method?
An accessor method is an instance method that gets or sets the value of a property of an object.
What is the difference between accessor and mutator methods?
An accessor is a class method used to read data members, while a mutator is a class method used to change data members.
Are accessor methods void?
An accessor method allows other objects to obtain the value of instance variables or static variables. A non-void method returns a single value. Its header includes the return type in place of the keyword void. Accessor methods that return primitive types use “return by value” where a copy of the value is returned.

Which are the built in accessor and mutator methods for object attributes?
Accessor and Mutator methods
- Accessor Method: This method is used to access the state of the object i.e, the data hidden in the object can be accessed from this method.
- Mutator Method: This method is used to mutate/modify the state of an object i.e, it alters the hidden value of the data variable.
What is an accessor method 1 point?
Accessor methods, also called get methods or getters, allow a way to get the value of each instance variable from outside of the class. In the next lesson, we will see mutator methods, also called set methods or setters, that allow a way to change the values of the instance variables.
What is the difference between accessor and mutators explain each with coded example?
An accessor is a class method used to read data members, while a mutator is a class method used to change data members. It’s best practice to make data members private (as in the example above) and only access them via accessors and mutators.
