How can I get 6 pack abs?

I’m a guy and I’m 25. I’m 6 feet and about 165 pounds. Recently, I have had some little fat on my abdomen and I really wanna get rid of it and get 6 pack abs which I never had and always wanted. I know nutrition play a major rule and I’m trying to stick to a healthy diet. I want to know what are the best exercises/workouts to get a toned abs or better a 6 pack abs? How many sets and reps? Thanks!
