Answer 1

● the condition in while() loop is always true , so the loop will never over , so print statement will never be reached .

Answer 2

Exit condition from the loop is missing.
Now it's always true so it always executes the loop.

Tl dr: Infinite loop

import java.util.*;

public class Main
{
public static void main(String[] args)
{
System.out.println("enter a line=");

Scanner c = new Scanner(System.in);
String s=c.nextLine();
Scanner c2=new Scanner(s);

String w,lg="";
while(c2.hasNext())
{
w=c2.next();
if(w.length()>lg.length())
lg=w;

}
System.out.println(lg+""+lg.length());
}
}

" String s=c.nextLine();
Scanner c2=new Scanner(s); "
