Java – the compiler says the return statement is missing, but I already have 3

It's strange My compiler says I missed a return statement, but I already have three

public int tortoiseMoves()
{
    int i = tGen();
    if (i >= 1 && i <= 5)
    {
        int fastplod = 3;
        return fastplod;
    }

    if (i >= 6 && i <= 8)
    {
        int slowplod = 1;
        return slowplod;
    }

    if (i >= 9 && i <= 10)
    {
        int slip = -6;
        return slip;
    }
}

Solution

You must ensure that a value is always returned If all your conditions fail, you won't return it

The fix will link your if statements because they are exclusive and use else to capture all other situations

public int tortoiseMoves() {
    int i = tGen();
    if (i >= 1 && i <= 5)
    {
        int fastplod = 3;
        return fastplod;
    }

    else if (i >= 6 && i <= 8)
    {
        int slowplod = 1;
        return slowplod;
    }

    else if (i >= 9 && i <= 10)
    {
        int slip = -6;
        return slip;
    }
    else {
        // return something or throw exception
        return 0;
    }
}
