Question

This is a Java Code :

public class test{
     public static void main(String args[]){
     number A = new number();
     System.out.println(A.b);       
    }   
}

class number{
    int b = 100;    
}

Is there a equivalent of above code in ruby without attr_accessor ?

Why can’t we access member variables using ‘.’ like in java ? or is there a way i am unaware of in ruby … ?

Answer 1

If you just want to pass around structured data, then you can use the Ruby Struct class, which will work more like you’d expect from your example:

Number = Struct.new(:value)
n = Number.new
n.value = 123
n.value # => 123
