LAPAPMF - List All Public And Package Members First

Enforces standard to improve readability. Methods/data in your class should be ordered properly.

Wrong

class LAPAPMF {
    private int attr;
    public void oper () {}
}

Tip: Place public and package members first, before protected and private ones.
Note: this rule is rather disputable. On the other hand, grouping members by functionality rather than by scope can also make understanding the code easier.

Right

class LAPAPMF {
    public void oper () {}
    private int attr;
}
