## Overview
We can get the value of a given key of a Hash by using the **`fetch(key)` method**. We only need to specify the `key` we want to get. This way, it will give us the value of the key we have specified.

## Syntax
```ruby
hash.fetch(key)
```
## Parameters
**`hash`**: This is the Hash whose keys we want to access.

**`key`**: This is the key whose value will be returned, if found.

## Return value
This method returns the value for the given `key`.
## Code example

# create hashes
h1 = {one: 1, two: 2, three: 3}
h2 = {name: "okwudili", stack: "ruby"}
h3 = {"foo": 0, "bar": 1}
h4 = { a: 100, b: 200, c: 300 }

# find key values
puts h1.fetch(:two)
puts h2.fetch(:name)
puts h3.fetch(:foo)
puts h4.fetch(:b)

## Code explanation

* **Lines 2–5**: We create some Hashes.
* **Lines 8–11**: We invoke the `fetch(key)` method on the Hashes, along with the arguments of the method. Then, we print the results to the console.

How can we access the entries of a Hash in Ruby?
