To merge two hashes in Ruby, you can use the merge method to combine the contents of both hashes into a new hash. This method provides a straightforward way to merge hashes.
We can merge two hashes in Ruby using the merge method, which creates a new hash that includes all key-value pairs from both hashes.
For example,
hash1
and hash2
with some key-value pairs. In this example, both hashes have string keys and integer values.merge
method to combine the contents of hash1
and hash2
into a new hash named merged_hash
.puts
function to verify the merge.hash1 = { 'one' => 1, 'two' => 2 }
hash2 = { 'three' => 3, 'four' => 4 }
# Merge the hashes using the merge method
merged_hash = hash1.merge(hash2)
# Print the merged hash
puts "Merged Hash: #{merged_hash}"
Merged Hash: {"one"=>1, "two"=>2, "three"=>3, "four"=>4}
We can merge two hashes in Ruby and handle overlapping keys using the merge method. If a key exists in both hashes, the value from the second hash will overwrite the value in the first hash.
For example,
hash1
and hash2
with some key-value pairs. In this example, both hashes have string keys and integer values, and there is an overlapping key.merge
method to combine the contents of hash1
and hash2
into a new hash named merged_hash
. The value from hash2
will overwrite the value from hash1
for overlapping keys.puts
function to verify the merge.hash1 = { 'one' => 1, 'two' => 2 }
hash2 = { 'two' => 22, 'three' => 3 }
# Merge the hashes using the merge method
merged_hash = hash1.merge(hash2)
# Print the merged hash
puts "Merged Hash: #{merged_hash}"
Merged Hash: {"one"=>1, "two"=>22, "three"=>3}
We can also merge two hashes in Ruby using the merge! method, which modifies the original hash by adding all key-value pairs from the second hash.
For example,
hash1
and hash2
with some key-value pairs. In this example, both hashes have string keys and integer values.merge!
method to add all key-value pairs from hash2
to hash1
.puts
function to verify the merge.hash1 = { 'one' => 1, 'two' => 2 }
hash2 = { 'three' => 3, 'four' => 4 }
# Merge hash2 into hash1 using merge!
hash1.merge!(hash2)
# Print the merged hash
puts "Merged Hash: #{hash1}"
Merged Hash: {"one"=>1, "two"=>2, "three"=>3, "four"=>4}
