problem with strings in Java...

[BigToque]

String namesStr;
int position = 0;

namesStr = JOptionPane.showInputDialog("Enter names separated by commas");

position = namesStr.indexOf(",");
firstStr = namesStr.subString(0, position);

-------------------

The problem in my code is in the line:
firstStr = namesStr.subString(0, position);

What is wrong with the code? is it not assigning the string between position 0 and the position of the first comma to the variable firstStr?

I have no idea what you are talking about. What IS it doing? What are you trying to do?

what's the error you get?

 

[slpaulson]

it's .substring(), not .subString()

caps matter

Hmmm, I think I'd use a tokenizer if I was trying to do something like that.

I want the user to enter a string of names separated by commas (eg. name1, name2, name3) into a variable called namesStr, then assign the portion of that string that conatins "name1" to a variable called firstStr.

Yeah I'd think a tokenizer would work better also.
Then you only need to use the tokenizer instead of finding the index of commas and making substrings, it would just do it all for you.

 

[gopunk]

sounds like it can't find the method subString then in the String class... perhaps it is substring like the other guys aid

 

[atom]

Did you define firststr somewhere else?

thats my problem. :|

why the hell would my damn textbook show it as .subString? stupid book. (and stupid me for not trying something different)

This is the correct answer. The other suggestions for using a StringTokenizer are also very valid. If all you're parsing on is the "," this would be a much better way of dealing with it.

.subString() is wrong. It's .substring()

Java != consistant
