Answer 1

Seems like Sololearn does not support an input using DataInputStream. Try to run this code on your local machine.

Answer 2

You need to use the Scanner class for this purpose.

It's working on tutorialpoint java compiler

Just write your input in Stdin and execute
MY OUTPUT
javac Program.java
Note: Program.java uses or overrides a deprecated API.
Note: Recompile with -Xlint:deprecation for details.
$java -Xmx128M -Xms16M Program
