UIManager.setLookAndFeel("com.jtattoo.plaf.aluminium.AluminiumLookAndFeel");

But the buttons became looked like this:

Does anyone know how to fix this (i mean without any lines inside them)

Answer 1

This problem occurs with the newer versions of JDK since the look and feel tools are less frequently used. I currently use JDK v1.8 on NetBeans and this issue isn't there atleast for the jbuttons. Although it's not generally recommended, you can try with the previous version of JDK to see if the issue persists or not If you are using Apache NetBeans you can check which version of JDK NetBeans is using by selecting Tools ⇾ Java Platforms from the NetBeans menu Further I would recommend you to either use Smart Look & Feel instead of aluminium or use the JDK v1.8 for better compatibility.
