Hi,

I am trying below challenge
http://codingbat.com/prob/p172267
i wrote as below
public String firstHalf(String str) {
int i=str.length();
if((i/2)==0)
return str.substring(0,(i/2)-1);
  
}

I got compilation error as below

Compile problems:


Error:      public String firstHalf(String str) {
                    ^^^^^^^^^^^^^^^^^^^^^
This method must return a result of type String

Possible problem: the if-statement structure may theoretically
allow a run to reach the end of the method without calling return.
Consider adding a last line in the method return some_value;
so a value is always returned.

see Example Code to help with compile proble

How to improve and fix my code
Please advise. thanks in advance
