How to fix Index 1 out of bounds for length 1 error [duplicate]

Question

I'm trying to build a Binary Search Tree. Below in my main method which reads from a file and inserts into the BST. However, I am getting an index out of bounds error and cannot figure out how to fix it. Any suggestion/solutions as to how it can be fixed?

public static void main(String[] args)
{
BinarySearchTree bst = new BinarySearchTree();
 
try
{
// you may modify the filepath, but not the filename
File file = new File("C:\\Users\\mbash\\Documents\\netflix_titles_alternative.csv");
     
Scanner token = new Scanner(file);
token.nextLine();                       
while(token.hasNext())                  
{
String line = token.nextLine();              
String tmp[] = line.split(";"); 
String type = tmp[0];
String title = tmp[1];
int releaseYear = Integer.parseInt(tmp[2]);
bst.insert(type, title, releaseYear);
}
token.close();
}
     
catch(FileNotFoundException e)
{
System.out.println(e.getMessage());
System.exit(0);
}

An indexoutofboundsexception occurs when you try to access an element of an array that does not exist.

Apparently, you have 1 line in your file that doesn't contain a title.

You can add a condition for example to make sure that tmp.length is greater than 3 each time you want to access tmp[0], tmp[1], and tmp[2].

    while(token.hasNext())                  
{
String line = token.nextLine();              
String tmp[] = line.split(";"); 
if (tmp.length >= 3) {
String type = tmp[0];
String title = tmp[1];
int releaseYear = Integer.parseInt(tmp[2]);
bst.insert(type, title, releaseYear);
}
    }
