Parameters:

d - the delay in milliseconds

public Timer(boolean r)

Creates a timer with specified repeat setting and the default delay. After 1000 miliseconds this timer will fire an ActionEvent. It may repeat, depending on r.

Parameters:

r - if true, reset and repeat after generating the event

public Timer(int d,
             boolean r)

Creates a timer with specified delay and repeat setting. After the specified delay this timer will fire an ActionEvent. It may repeat, depending on r.

Parameters:

d - the delay in milliseconds

r - if true, reset and repeat after generating the event
