How to use Scanner multiple times?

Question

So I want to upload a code to Code Playground that goes like this:
1. User reads a printed menu
2. User enters a value
3. User sees the output on the screen
4. User enters another value and so on

This website gives me error, because (I think) it only accepts user's input when running the program for the first time. Is there a workaround?

Error i get:
Exception in thread "main" java.util.NoSuchElementException: No line found
at java.util.Scanner.nextLine(Unknown Source)
at Program.main(Program.java:24)

Answer 1

Verbal13 Unfortunately there's no workaround as it's how online compiler works.

Unlike the program we run it our PC, the server cannot wait for user input indefinitely as the resource was shared by everyone.

Therefore if multiple inputs are required, we will need to send it in one-go separated by new-line.

Sololearn has a restricted input thing. You have to write input on multiple lines codePlayground to understand.

Answer 3

Also, you can only write input(whatever number of input you want) once on codePlayground. If you take user input, output something on screen and try to take input again, it will not work on codePlayground.
