Hi Alex -- I still doubt the code you quoted is really what you want -- for
one thing, do you want the loops to break when you hit an assignment? What
exactly do you want the function to do? sIf you don't break when you hit the
if/else you will have the problem of assigning ok multiple times. I agree
with others that writing code and shifting it around until it compiles is
dangerous -- runtime bugs are much harder to diagnose and correct than
compile time bugs.
I only say this to ensure you indeed are hacking happily...*smile*

Subject: Re: method saying "no return statement" when there IS one
I had an if...else inside a double for loop, ensuring that no
slot of a 2d array was >=2. I then moved the if outside of the
loops and got rid of the else completely, since I initialized the
variable that would be changed if a 2 or greater was encountered
to be okay.
The first try was like this (pretend all braces and declarations
are okay):
int ok=0; //1 is good, 0 is bad
for(i=0;i<grid.length;i++){
for(j=0;j<grid[i].length;j++){
if(grid[i][j]>=2){
ok=0;
else{
ok=1;
return ok;
Now the method that worked:
int ok=1; //1 is good, 0 is bad
for(i=0;i<grid.length;i++){
for(j=0;j<grid[i].length;j++){
if(grid[i][j]>=2){
ok=0;
return ok;
Have a great day,
Alex
