Error on myList.get(2) - When myList.size() is 8

Hey everyone,

I have been programming in java for a while now but have never once come across this...

I am opening a text file and reading it into a string variable using
myVar = myVar + inputLine;

I am then splitting it

Code :

---

 String[] tData;
  for(int i =0; i < information.length ; i++){
	System.out.println(information[i]); // OUTPUTS: 100-83-42-11-56-38-62-98
    tData = information[i].split("-");
	List<String> wordList = Arrays.asList(tData);
	System.out.println(wordList.size()); //This is outputting 8
        System.out.println(wordList.get(4)); //This gives, Error: 4 when running program (compiles fine)
	}

---

I was hoping some one could help me figure out where I am going wrong?

As far as I can see this should work fine?

Any ideas would be appreciated

Thanks,
Kriogenic.

What is the actual error?

What happens when you loop through your List, printing out each element?

What kind of error is it giving you? Its hard to determine what context that piece of code is running in, and when exactly it is failing.

It compiles fine but when I run instead of the output i want I get
Error: 1

Code :

---

for(int j =0; j < wordList.size() ; j++){
	System.out.println(wordList.size());	 //Gives me 8
	System.out.println(j);	 //gets to 1
	System.out.println(wordList.get(j)); //Error: 1 
	}

What is the error?

Quote:

---

wordList.get(j)

---

What value is returned by the get method? Can it be: "Error: 1"
Change your println to:
System.out.println(">"+wordList.get(j) +"<");

You can probably find more information by visiting the Java API documentation site. I think I used .size() method in LinkedList today and it worked great. Just keep tweaking around if you still need to find the solution.
