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.
