Accessors are methods defined inside classes to access the private variables of the class. It is always a good practice to have instance variables as private so that, other classes cannot access them directly. This would avoid unwanted modification of data. These variables can be accessed only via their respective accessor methods. Ex: public class Test { private String name = ""; public String getName(){ return this.name; } Public void setName(String val){ this.name = val; } } Here getName and setName are the accessor methods for the variable name.

What method gets a value from a class s field but does not change it?
An accessor method can be used to get a value from a class without changing the value.
What is an accessor?
An accessor is a method in a Java Bean that is used to access the private variables of the class. Usually instance variables in a bean are declared as private and they can be accessed only via these accessor methods. Ex: public class Employee { private String name = ""; private int age = 0; public String getName(){ return this.name; } public void setName(String nm){ this.name = nm; } public int getAge(){ return this.age; } public void setAge(int ag){ this.age = ag; } } In the above example name and age are instance variables and the methods beginning with get and set are the accessor methods.
Are accessor member functions a sign of poor class design?
No, accessor member functions are a sign of good class design, particularly in terms of data encapsulation.
What are accessors and mutator method in java?
An accessor is a method that accesses the contents of an object but does not modify that object. In the simplest case, an accessor just returns the value of one of the fields. In general, an accessor performs some computation using the fields as long as that computation does not modify any of the fields. Mutators A mutator is a method that can modify an object. In the simplest case, a mutator just assigns a new value to one of the fields. In general, a mutator performs some computation and modifies any number of fields. Sometimes, accessors are called 'getter' methods and mutators are called 'setter' methods.
In c plus plus what is Mutable keyword?
mutable keyword can only be applied to non-static and non-constant member of a class. It indicates that the corresponding data member can be modified even from the constant function. (Constant function: is a function marked with the keyword const) For eg. class x { private: mutable int query_count; int value; public: int get_value() const { query_count++; return value; } }; In the code above member query_count is marked with keyword mutable. Hence it's value can be modified from constant function get_value().
