Java Accessor(getter): The java Accessor or getter is a conventional method used to retrieve the value of variables. The accessor or getter is a method that does not changes the state of an object. The accessor method tells the object to compute something without changing its state. For example, //calling the accessor method double height = rectangle.getHeight(); In the above example, the object “rectangle” tells the method “getHeight()” to find the height. Here, the method only finds the value and it save to the variable “height”. Here, the method “getHeight()” is a setter. Java Mutator(setter): The java Mutator or setter is a conventional method used to update value of variables. The mutator or setter is a method that change the object’s state. That is mutator modifies the object by which it is called. This is happened when the variable values get updated. For example, //calling the mutator method rectangle.setHeight(1000); In the above example, the method “setHeight()” is a mutator because it initializes some values to the members of the object “rectangle” and thus changes the state of the object.

Program Plan Intro

Java Accessor(getter):

The java Accessor or getter is a conventional method used to retrieve the value of variables.

The accessor or getter is a method that does not changes the state of an object. The accessor method tells the object to compute something without changing its state.

For example,
//calling the accessor method

double height = rectangle.getHeight();

In the above example, the object “rectangle” tells the method “getHeight()” to find the height. Here, the method only finds the value and it save to the variable “height”.

Here, the method “getHeight()” is a setter.

Java Mutator(setter):

The java Mutator or setter is a conventional method used to update value of variables.

The mutator or setter is a method that change the object’s state. That is mutator modifies the object by which it is called. This is happened when the variable values get updated.

For example,

//calling the mutator method

rectangle.setHeight(1000);

In the above example, the method “setHeight()” is a mutator because it initializes some values to the members of the object “rectangle” and thus changes the state of the object.
