Do you use Virtual Box VM... Please help with this.

Question

hey everyone I'm extremely new with all this stuff...
I have a iMac 10.5.4 with the most current version of Virtual Box.
When i load Virtual Box everything is rocking and extremely cool... but after an hour or so my network/server connections dies off on the mac side.
when i go to GO >> Connect to Server >>
smb://ipaddress
I get this pop up...
error connecting to the server >>
I click OK and i get an error code -36
the only way for me to connect again to the server is to shut down everything and restart the iMac it works just fine and i load VB back up and than everything works for about another hour or so and than i have to restart everything again.
any clues to my issue?
thanks for helping a newbie!

Answer 1

...but since you are learning, and would like to know where was the bug, I tried your code and updated it.
The only two small problems I found:
1. You have a while loop that checks if there are more tokens.. it's not needed and this while loop will only run because by the second run, you would have consumed all the tokens in the for loop, check would fail and while loop will be exited. [I have removed this while loop in my version below]
2. Now, here is the bug:your for loop has a condition that evaluates (i < st.countTokens()).
Now count tokens will only return "remaining" tokens. Assuming test string "this is a test", countTokens return 4. Then as you consume the first token, it is 3, then 2 then 1. All this while for loop's i is going 1,2...
i = 0, countTokens = 4
i = 1, countTokens = 3
i = 2, countTokens = 2, check fails, and for loop is exited.
So all you have in your array is first two tokens. Rest of the array is null as it was when you created the array.
So then when you loop back and check index 3,2,1,0.. 3 and 2 elements are still nill, that's why you get the result you are getting.
Here is the fixed code:
String sentence = "this is second test"; //String variable to hold user input
String output = ""; //String variable to enable display of output
String buffer = "";//String variable to hold output
st = new StringTokenizer(sentence);
int tokenCount = st.countTokens();
//Array to hold tokens
String tokenHolder[] = new String[tokenCount];
//Walk through the tokens
for (int i = 0; i < tokenCount; i++)
     tokenHolder[i] = st.nextToken();
String reversedTokens[] = new String[tokenCount];
//Walk through the array in reverse
for (int j = tokenCount-1; j >= 0; j--)
//Add the reversed token to the ouptut string
output += tokenHolder[j] + " ";
System.out.println(output);
}
