title: Java application that uses multiple timers
body: <p>Hi all and thanks for reading this.
  i have an application and i want to use multiple timers on it. 
  it will read from a list of instructions some instructions and will tell you what to do, keeping track of time for each instruction's time and notifying you when timer is over. instruction can include other instructions and goes on.
  i m passing the time as : <strong>double minutes</strong> to each instruction.</p>
  
  <p><strong>So it should work like this.</strong></p>
  
  <p>start instruction1 - start timer1</p>
  
  <p>if it includes other, start instruction1.1 - start timer1.1</p>
  
  <p>start instruction2 - start timer2 .....etc.etc..</p>
  
  <p>every time a timer goes of it should notify me</p>
  
  <p><strong>i would like to get suggestions on how to do this....</strong>
  any tutorials, examples, links pseudocode, sample code are welcome. Thank you</p>
