My Java experience is not that high either, so anyone feel free to correct me. But AFAIK, the general convention is to write two methods like so:
public string getMyString() {
// return it here
}
public void setMyString(string myString) {
// set it here
}

Counting occurrences in vim |

In order to know how many times a pattern exists in current buffer, I do:
