如何使用TimerTask将旧的Java Timer更新为新的Java Timer

Question

I have some older Java code that looks like this:

timer = new Timer( 1000, (ActionListener) this );

In the newest Java (I'm using Java 8 build 129 and JavaFX), Timer needs a TimerTask and I'm not sure how to attach that to my ActionListener...

Answer 1

There are two Timer classes in the jdk: java.util.Timer and javax.swing.Timer . The one that takes an ActionListener is the latter. The one that works with TimerTasks is the former.

Note that the constructor's signature has not changed in Java 8 .

So you should probably check your imports.

NOTE: since you are upgrading to Java 8, you may as well take the opportunity to avoid obsolete classes (cf. javadocs) and use a ScheduledExecutorService .
