如何在标签中设置用户定义的值

Question

I am working on an JavaFX application and I have to set system related information in a JavaFX label.

I am doing like given as below:

systemInfo.setHdUsageTxt(Integer.toString(Runtime.getRuntime().availableProcessors()));

Here hdUsageTxt is a JavaFX label in which I have to set number of available processors at a time. But it is not setting String or Integer value in this label. And giving exception. Please suggest which type of data JavaFX label and TextField takes and how to set value in it?

Answer 1

Try

systemInfo.getHdUsageTxt().setText(Integer.toString(Runtime.getRuntime().availableProcessors()));

if didn't help, post your exception stack trace.
Both javafx.scene.control.Label and javafx.scene.control.TextField have a text property which is type of javafx.beans.property.StringProperty . You can access to this property's value with setText(String text) and getText() .
