ASSIGN TIME LIMIT

    import java.util.*;
    class enter{
    public static void main(String args[]){
    int a;

    Scanner p=new Scanner(System.in);
/*add some command such  a time limit 
assign for next two commands*/
    a=p.nextInt();
    System.out.println(a);
    System.out.println("i love java");
}
    }

i.e if a user do not give any value for any time limit (say 5 sec) then after 5 sec next command will be executed i.e output will be " i love java".
