Unexpected behavior of Scanner

 

This question already has an answer here:

  • Close a Scanner linked to System.in 5 answers

    • The reason is quite simple, closing the 1st scanner object closes internally too the input stream which is actually being used by the second scanner

    your options are: use only one scanner or close those when you are sure all of them are not required anymore..
