Java netbeans project does not take effect of changes

Question

I have a netbeans project (java desktop application) and I opened it after 2 months. It includes a tabbedpane. When I tried to add a new choice as a new tab although it appears good in design view when I run it it does not contained the title I gave in the tab.Actually it does not write anything. When I tried to change the name in one of the old tabs it does not have any effect when I run it neither. Is there a reasonable answer?

正如Brian Roach所说，但我也建议您自动勾选“ build”，这样您每次进行更改时都不必运行clean和build周期。
