Answer 1

The problem seems to be how the input is handled. Maybe clear the scanner before accessing it with the nextLine() statement. This is a nasty fix which works, but should be rewritten to properly handle the input. https://code.sololearn.com/c81lmP0Nl2t5/?ref=app

You can also check

if (input.nextLine() != null)

Answer 3

As you can see, the problem is caused due to the nextInt() statement not catching the given "\n" on the line in input. This is caught by your nextLine() statement therefore causing an empty array.

Answer 4

You're accessing index 1 of an array of length 1. Array indexing starts from zero in Java. You should access index 0 instead.

Answer 5

But. As you see, i splitted the string "str2 str3 str4 str5" by " "(space) delimiter (using split function). So this array must be a 4-index array and should support index 0 1 2 3.
