Answer 1

your syntax for if-else is wrong there should be an if after the else. Here is the correct syntax for if-else statement

int testscore = 76;
char grade;

if (testscore >= 90) {
    grade = 'A';
} else if (testscore >= 80) {
    grade = 'B';
} else if (testscore >= 70) {
    grade = 'C';
} else if (testscore >= 60) {
    grade = 'D';
} else {
    grade = 'F';
}

in your code the correct syntax would be

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

Answer 2

In an if-else block, the else statement does not have a condition. If you would like to add a condition, change it to an if-else if statement.

else if (value < mYelloStep)
    return effort.WALKING;
else
    return null;

Answer 3

You have a condition after the else.

Try with else if

Answer 4

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)

Answer 5

Please use else if (condn). In java if you use single else then it means none of the above conditions got satisfied but else is never followed by a condition unless you use else-if.

ie.

..
else if (value < mYellowStep)
return effort.WALKING;
}

simply use
..
else
 return effort.WALKING
}
