statistical t test to compare two groups

Hello

I have a basic statistic question.

I have two sets of dataset. I would like to test where the mean of the first group is significantly larger than the other group.

I am wondering whether there is direct test or not.

What I thought is that

1) do the t-test to compare the mean of these two group is significantly different or not.

2) if it is, compare the mean of those two group.

My question is that
is there any direct way to compare the first mean is significantly larger than the second without this two steps? for example. H0 : Mean(group1) > Mean(group2)

It will be really helpful.

THanks.
