Return int as boolean

Question

I am a beginner so please bear with me. I decompiled the source code of a professional application. When I copied the source code into eclipse, an error came up with the following code( the error is with the return type):

public boolean method(){
...
...
   for(int i = 0; ; i = 1){
       return i;
}

How can I change the code to keep it correct but keep the functionality?

Answer 1

You can cast i as a boolean , or change return i; to return i != 0; , which will be true for all non-zero values of i , and false if i == 0 .

As a side note, I really see no reason to wrap a return in a for loop. In this case, you might as well just replace both of those lines with return 0; (or return false; , to match the method signature).

Answer 2

Change the return type from boolean to int .

As you can see, your method is returning i which is declared as an int in the for loop, so the return type of your method has to be the same as the type of the variable it returns.
