How do getters and setters work?

Tutorial is not really required for this. Read up on encapsulation private String myField; //”private” means access to this is restricted to the class. public String getMyField() { //include validation, logic, logging or whatever you like here return this.myField; } public void setMyField(String value) { //include more logic this.myField = value; }
