title: TimerTask vs Timer vs Thread?
body: <p>I'm trying to show Date and time continuously on a JLabel. So on the last tutorial I've watched.the speaker said "You must Use this threads whenever necessary because it takes memory in your program".</p>
  
  <p>So I search other alternatives and i find Timer and TimerTask which is the most efficient way to use on the long run of the program?</p>
