    } catch (InterruptedException e) {
        // TODO Auto-generated catch block
        e.printStackTrace();
    }

    System.out.println("start...................");
    fill(1000);



}

public static void fill(int n) {

    List<JconsoleDemo> list=new ArrayList<>();

    for(int i=0;i<n;i++) {
        try {
            Thread.sleep(100);
        } catch (InterruptedException e) {
            e.printStackTrace();
