Why does this line not work, in principle, without errors?

Question

Java

Tell me guys. I am learning to build forms in Java: I wrote for the switch
onna.setName(onna.isEnabled()?"1000":"2000");
it seemed to me that in the On position it should be called 1000, but vice versa - 2000. But there is no name at all! Just the button and the icon remained. Everything works, no compiler errors..

This option also passed without errors, but did not give a visual effect:
if (onna.isEnabled())
{
onna.setName("1000");
}
onna.setName("2000");

Answer 1

Debugger looked - these functions are generally called? Are they written in the switch event handler?

Answer 2

And the state of the button is changed through setEnabled?
Or are you just poking at it?
Are you using swing
After changing the name, do you call revalidate or repaint?

Answer 3

Try:
onna.setName((onna.isEnabled()) ? "1000" : "2000");
Or what would be clearer:
String onnaName = (onna.isEnabled()) ? "1000" : "2000";
onna.setNmae(onnaName);
