RE: method saying "no return statement" when there IS one

I am using the Sun compiler, the latest version. I use EdSharp to write and compile, but I think EdSharp just looks for a compiler already on my system. If not then I am using the compiler in EdSharp. 


Have a great day,
Alex

You have to have a value if your returning to a into variable 
what compiler

are you using?

I tried that and instead of saying "missing return statement" it 
said
"missing return value". I just put "return;" just before the 
final

right-brace of the method.

If you have all the opening and closing braces the compiler might

be

complaining because you don't have a sure return.  This is not

normal for a

compiler but I don't know what compiler your using.  So you can

try putting

a return at the end of the function right before the last } and

that should

do the trick.

Odd, I put all the braces in my original email.  I opened the

method, two

for loops, an if statement, and an else statement and closed them

all.  My

bn, on which I wrote that message, must have not liked it that I

put them

all on separate lines; it seems to do odd things with punctuation

just

before a new line if that punctuation is not connected to a word.



Have a great day,
Alex

Hi Alex, You have several opening braces with no closing brace.

Both "for"

statements have an opening brace but no closing brace.  Also,

your "if" and

"else" statements have opening braces with no closing brace.

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
