Dear friends,
I have created a string buffer.
I have read character by character from buffer using a method and stored
in a string object
like,
@test = String.new
The method iteration process continues till @flag=1. So for every
iteration of method a string object(@test) is returned from the method.
Now i want to move this returned string object @test into a hash. How
can i move string objects into hash.
I need to store all strings that are returned(@test) till flag=1 in a
hash. I dont want to use an array to store the values.
Please help me to do this process.
Thanks in advance
Regards,
Jose Martin

This is an example of a hash:
h = {“a”=>“circle”, “b”=>“square”, “c”=>“triangle”}
puts h[“a”]
–output:–
circle
Note that every element of a hash is a key/value pair. You say, “I want
to put my strings into a hash”, but the elements of a hash are not
single objects–the elements of a hash are pairs of objects. If your
strings are to be the values, what do you want to be the keys?
Thank you very much for your information. what you said is right. I want
to put my strings into hash. But two objects are required for hash. Is
it possibble to use hashcode method to be used as key and string as a
value.
If its possible please suggest a way to do so because i need to put my
strings into a hash.
Thanks in advance…

Just out of curiosity, what are your keys for the values? In other
words if I have “hello” and “goodbye”, what key do you use to
correspond to “hello” and what key for “goodbye” that would require a
Hash object?

The big question is “why?” It would be helpful if you could describe
your purpose. I don’t see any value in using the #hash function as a
key.

Yeah, you’re just creating a hash that looks like this:
h = {‘hello’=>‘hello’, ‘goodbye’=>‘goodbye’}

What exactly do you mean by that? There is String and StringIO - why
create another class that can hold strings?
I have read character by character from buffer using a method and stored
in a string object
like,
@test = String.new
This does not store anything in a String object. It just creates a new
empty String.
The method iteration process continues till @flag=1. So for every
iteration of method a string object(@test) is returned from the method.
Why? What is the purpose of all this?
Now i want to move this returned string object @test into a hash. How
can i move string objects into hash.
What exactly do you mean by “move”? You can put Strings into a Hash -
as keys and values. But why?
I need to store all strings that are returned(@test) till flag=1 in a
hash. I dont want to use an array to store the values.
Why not an Array? A Hash will loose the insertion order.
Please help me to do this process.
Please provide enough information that someone can come up with proper
suggestions.

…and to retrieve a value from the hash, you would write:
x = ‘hello’
puts h[x]
but you could just write:
puts x
and dispense with the hash altogether.
Dear every one,
The following code is a sample code i tried to work out my task.
class Sample
def initialize
@test = String.new
end
def calculate!
if @character == ‘C’
string_manipulate!
end
end
def string_manipulate
while @character != ‘A’
@character = read_character! # method to read character from
buffer
@test << @character
end
if @character == ‘A’
calculate!
else
end
@test
end
end
I need to write a method now to retrieve @test string from
string_manipulate method and store in a hash. Each time a @test string
is returned it should be stored in a hash not in an array. I have used
array to store it but now my task need to do it using hash.
so could anyone help me out to write a method to retrieve string objects
using a hash.
Thanks in advance…
Regards,
Jose Martin
