java - TimerTask() not doing what was supposed to, only printing one time -

public static void main(string[] args) {          timer ttt = new timer();         timertask test = new timertask() {              @override             public void run() {                  system.out.println("in");                         }                  };          ttt.schedule(test, 1000); } 

this supposed print "in" every second printing 1 time. tips? thank you

what

you're using one-shot version of schedule. use overloaded version accepts interval period:

ttt.schedule(test, 0, 1000);

aside: newer executorservice preferred on java.util.timer. timer has 1 executing thread, long-running task can delay other tasks. executorservice can operate using thread pool. discussed more here
