“Missing return statement” within if / for / while

Question

I have a question regarding return statements used within if() while() or for() statements. As you can see in the following method, it

Answer 1

Try with, as if if condition returns false, so it will return empty otherwise nothing to return.

public String myMethod()
{
    if(condition)
    {
       return x;
    }
return ""
}

Because the compiler doesn't know if any of those if blocks will ever be reached, so it's giving you an error.
