如何将对象存储在Ruby中的哈希中？

Question

I have a hash to objects MyObject in a hash:

inst = Hash.new(0)
inst = {"val1" => MyObject.new(0x18,3,4)}

But when I want to get the element:

puts inst["val1"]

I get an error:

MyObject:0x00000002468690

Answer 1

Hash are Key-value pair . in this case what you are getting is value for the given key ( which is "val1"),which is instance of MyObject class.
