How java.util.NoSuchElementException (basic program)

Question

java.util.NoSuchElementException problem... I used two scanners

scanbud()

and

scabudrad()

Answer 1

The reason is here:

scanbudRad.close();     

you are using multiple instances of the scanner, _BUT as soon as you closes a scanner, that instance close under the hood too the input stream which is shared between all other remaining instances... after that, trying to read /get something from an scanner object with a InputStream closed throws the exception.
