# Ruby program to implement getter/setter method using

    attr_accessor  :ins_var

obj.ins_var = "Hii";
val = obj.ins_var;

Value is: Hello
Value is: Hii

Explanation:

In the above program, we created a class Sample. In the Sample class, we implemented constructor and getter, setter methods using attr_accessor accessor. Then we created the object of the Sample class with the initial value. After that, we used getter/setter methods to get/set the value of the ins_var variable and print the result.
