SQL: Select sum of each individual value of a column

There is a column that can have several values. I want to select a count of how many times each distinct value occurs in the entire set. I feel like there's probably an obvious solution but it's eluding me. I'll show input & expected output, hopefully it's obvious enough that you'll understand.

This is example data:

|-------|
| class |
|-------|
| 5     |
| 5     |
| 12    |
| 4     |
| 12    |
|-------|

This is the output I'm trying to get:

|-------|-------|
| class | count |
|-------|-------|
| 5     | 2     |
| 12    | 2     |
| 4     | 1     |
|-------|-------|
