Note: You can not pass parameters in get method.
syntax: 
            get Method_name(){

            }

Setter: The set syntax binds an object property to a function to be called when there is an attempt to set that property. It can also be used in classes.

Note: You can pass only one parameters in get method.

            set Method_name(obj){
                
            }
