How can I apply a Trigger and an Apex Class I created in a sandbox to my production ?

I created with a lot of help a trigger with its Apex Class in a sandbox. Now I would like to have it in my production to really use it. 
How can I do that ? 

Please help me, I spend a lot of time creating these, I cannot have done it for nothing. Thank you in advance.

Do you want to deploy this? If so, you can do the same using Change set. However you need to 75% code coverage for the same.

Inorder to deploy we can do in following ways: 
1) Using Change Sets

2) Using ANT tool

For you I can suggest the first option to deploy the things. Which is an Out of box functionality given by Salesforce.
