i have working with twp timer,the code below

using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Linq;
using System.Text;
using System.Windows.Forms;

namespace example
{
    public partial class Form1 : Form
    {
        int i = 0;
        int j = 0;
        public Form1()
        {
            InitializeComponent();
            timer1.Interval = 3000;
        }

        private void button1_Click(object sender, EventArgs e)
        {
            timer1.Enabled = true;

        }

        private void timer1_Tick(object sender, EventArgs e)
        {
            i++;
            timer2.Enabled = true;
            if (i < 3)
                time1(i);
            else
                timer1.Enabled = false;


        }

        private void timer2_Tick(object sender, EventArgs e)
        {
            j++;
            timer2.Interval = timer1.Interval / 5;
            if (j < 5)
                time2(j);
            else
                timer2.Enabled = false;

        }

        private void time1(int i)
        {

            MessageBox.Show(i.ToString(), "First Timer");
        }

        private void time2(int j)
        {
            MessageBox.Show(j.ToString(), "SecondTimer");
        }
    }
}

when running this program it gives output like this firsttimer:1 secondTimer:1 secondTimer:2 secondTimer:3 secondTimer:4 firsttimer:2

in message box but when debugging debug cannot move that order.after finisheg the secondtimer:2 it gose back to first timer. but i need to go for how i am output get i need for this in another application. why it occurs
