for loop

my compiler won't compile this for loop

for (int cell : locationCells)

it says that the colon should be a semicolon... i am using a book to do this program and that is what it calls for and i know there are for loops as such

for (int i = 0; i < 10; i++)

i can't figure out what the problem it ��??

what version of the JVM do you have? type:

java -version

the enhance for-loop was put into 1.5, so if you're not running that, i can see why it wouldn't work.

i checked that too to make sure and i have java 1.5

can you post the relevant code and the EXACT error message your getting? please use the code tags around your code, to preserve formatting. just use the handy "Instant UBB Code" buttons below to get the tags, then paste your code inside...

errr... the buttons are below when you are posting your reply, not when you're just viewing the thread, if i didn't make that clear

This is the class that gives me the error
errors are

';' expected on line 17
illegal start of expression on line 31
illegal start of expression on line 32

1public class SimpleDotCom
2{
3int[] locationCells;
4int numOfHits = 0;
5
6public void setLocationCells(int[] locs)
7{
8locationCells = locs;
9}
10
11public String checkYourself(String stringGuess)
12{
13int guess = Integer.parseInt(stringGuess);
14String result = "miss";
15//int cell = 0;
16for (int cell : locationCells) // i = 0; i < 7; i ++)
17{
18if (guess == cell)
19{
20result = "hit";
21numOfHits++;
22//cell++;
23break;
24}
25}
26if (numOfHits == locationCells.length)
27{
28result = "kill";
29}
30System.out.println(result);
31return result;
32}
33}

Execute:
javac -J-version
Ensure that you are not passing the -source or -target switch to a 1.5 level compiler.

It compiles without an error for me. When I execute the command java -version on my console I get this

java version "1.5.0_05"
Java(TM) 2 Runtime Environment, Standard Edition (build 1.5.0_05-b05)
Java HotSpot(TM) Client VM (build 1.5.0_05-b05, mixed mode, sharing)

ok i figured out the problem .. it was the compiler that i was using wasn't using java 5. it was using an older version so when i tryed it in bluej it compiles and runs. before i was using Jcreator and i don't know how to (or if you can) change the version of java it compiles with. But original problem fixed

ok now i am saposed to upgrade the code to ask for a userinput as well and use ArrayList to make my life easyer but again i get a compile problem not with the extended for loop anymore though now the error is

that isn't saposed to be a smile. i didn't use the code button.

When you are composing a post, there is a checkbox near the bottom of the page to "Disable smilies in this post." (Otherwise, a semicolon followed by a closing parenthesis will display as a winking smilie.)

You can go back and edit your own posts by clicking on the paper/pencil icon.

thank you

i am still can't find/figure out why i keep getting that error though.

The error message...

setLocationCells(java.util.ArrayList<java.lang.String>) in DotCom cannot be applied to (int[])

...is telling you that your method setLocationCells is expecting an ArrayList (of Strings), but you are trying to call it using an int array instead.
