Why is the error "missing return statement"

[Varuna Seneviratna]

   
   class TestDriveSimpleDotcom
{
public static void main(String[] args)
{
SimpleDotcom sm=new SimpleDotcom();
 

//The Location cells
int[] locCells={2,3,4};
 

sm.setLocationCells(locCells);
 
sm.setUserGuess("2");
 
String result=sm.checkUserGuess();
 
String checkResult="failed";
 
if(checkResult.equals("hit"))
{
checkResult="Passed";
 
}
 
System.out.println(checkResult);
 
}
}
 

 

   
   class SimpleDotcom
{
private int[] locationCells;
private int numOfHits;
private String userGuess;
 
void setLocationCells(int[] cellLocations)
{
locationCells=cellLocations;
}
void setUserGuess(String uG)
{
userGuess=uG;
}
public String checkUserGuess()
{
int uGuess=Integer.parseInt(userGuess);
 
for(int cellLoc:locationCells)
{
//String result="miss";
if(cellLoc==uGuess)
{

return "hit";
//result="hit";
//numOfHits++;
//break;
}
else{
return "miss"
}
 
}
}
}
 

 
 

The TestDrive has the "main"
When the return statement is included why do I get the error "Missing return statement".Is there a particular place where the return statement should be situated.

The checkUserGuess does not in all cases return something. If the locationCells array is empty, no return statement is ever reached.

You have to place return statement out of "for loop" in side of checkUserGuess() method.

Agree. In fact the return statements, if they are actually executed, will break the repetition by terminating the loop.
