Answer 1

NoSuchElementException arises because you don't check the availability of data in the Scanner before reading it.
change line#27 to
while(sc.hasNext())

also your code doesn't replace 10 to "ten", appen it.

Answer 2

Error was occur in line no 29 becz you take input from user inside while loop and that loop run infnite, However your programm still incorrect.

Answer 3

Thanks It's fixed!

Answer 4

I recommend a solution with switch statement. This is much better structured and more suitable for these cases.

Answer 5

I dont wanna recode so suggest me the error Ja Play

Answer 6

Ayush Pandey You must replace also 10 with ten.
As for the exception 🤷‍♂️

Answer 7

Answer 8

This way you can better see what you have done and fix your solution by yourself. And this is much more valuable for a learning process 🙃

Answer 9

Answer 10

andriy kan how can that exception be fixed ?

Answer 11

@Ayush Pandey
To fix that exception you should replace true in line #27 with sc.hasNext()
See my previous post, I wrote about it.

Answer 12

Ayush Pandey Instead of arguing, have you tried replacing 10 also, as per description and my first answer.

Answer 13

Add try catch for your exception and make that meaningful
