Answer 1

It's either just else without condition or else if with condition, see "The if-then and if-then-else Statements".

Without condition:

public Effort getStep(int value) {
    if (value < mGreenStep)
        return Effort.GURU;
    else
        return Effort.WALKING;
}

With condition:

public Effort getStep(int value) {
    if (value < mGreenStep)
        return Effort.GURU;
    else if (value < mYelloStep)
        return Effort.WALKING;
    // missing default
}

Note that the second version will not compile either as you have declared to return an Effort but there is no branch that covers cases where neither value < mGreenStep nor value < mYelloStep is true, so you would need an additional else for that as well.

As a side note: While it is valid to use if/else statements without brackets ({}) it is strongly recommended to always include them:

public Effort getStep(int value) {
    if (value < mGreenStep) {
        return Effort.GURU;
    } else {
        return Effort.WALKING;
    }
}

(I'm ignoring the extra } in your code as this is probably only from copy&paste)
