It is possible for the second return never to get called; thus, the function
never to return anything.
You have to have a return at the end of the function to guarantee to the
compiler you will always return something.
Take care,

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
