Update same label after setting timer GWT

Question

我想每隔5s更新一次标签，它应该是RootLayoutPanel中的唯一标签。当前每隔5s添加一个新标签，但我希望更新相同的标签。能否建议一个方法。

Answer 1

Use Timer to repeat after 5 sec.

Here is code:

import com.google.gwt.user.client.Timer;

final Label label=new Label("Hello ");
Timer timer=new Timer(){

    @Override
    public void run() {
        label.setText("Hello "+Math.random()*100);
    }

};
timer.scheduleRepeating(5000);
RootPanel.get().add(label);
