Well, you need a return at the end of the function after the loops to catch
the boundary condition that the j loop never executes.
But look at your code again: aren't you always returning on the first
iteration of the j loop, assuming the j loop executes? Are you sure you
want to do this?

Subject: method saying "no return statement" when there IS one
Hi all. Yet again I have what to many of you is no doubt a very
simple question, but it is not making sense. I have a method
that is checking collisions on a battleship grid. It is an
integer method that returns 0 if a collision is detected and 1 if
there is no problem. The compiler, however, keeps saying that I
am missing a return statement when I clearly have two, one in an
if statement and the second in a related else. Here is the
method:
public static int checkCollisions(int[][] grid){
int i,j;
for(i=0;i<grid.length;i++){
for(j=0;j<grid[i].length;j++){
if(grid[i][j]<=2){
return 0;
else{
return 1;
Have a great day,
Alex
