Ask the user for a filename. Display the oldest car for every manufacturer from that file. If two cars have the same year, compare based on the VIN.

My code is producing an error an wont run in the program
Enter filename\n
car-list-3.txtENTER
Exception in thread "main" java.lang.ArrayIndexOutOfBoundsException: Index 1 out of bounds for length 1\n
\tat OldestCarsByMake.main(OldestCarsByMake.java:68)\n
i am not sure where i am going wrong with my code, can an expert fix my code and explain the issue
i need it to produce
