why my compiler not take input?

Question

import java.util.*;

// Compiler version JDK 11.0.2

class Dcoder
{
public static void main(String args[])
{
System.out.println("enter your marks!");
Scanner s=new Scanner(System.in);
int marks=s.nextInt();
if(marks>=65&& marks<=100)
{
System.out.println("exelent");
}else if(marks>=45&& marks<=65)
{System.out.println("second devision");}

else{
System.out.println ("fail");
}}}

Answer 1

It asks for input in Playground, not sure what's wrong with your machine.

Apart from the input issue, there is a possible typo in the conditions. Range of "second devision" is from 45 ~ 65 but range of "excellent" is from 60 ~ 100.
