List of 4 digit combination using number 0 through 9?

Oh, dude, you want me to list out every possible 4-digit combination using numbers 0 through 9? That's like asking me to count all the grains of sand on a beach! There are 10,000 different combinations, so you might want to grab a snack and get comfy while I rattle them off... or you could just use a combination generator online, but hey, where's the fun in that, right?
