java - Error while setting LookAndFeel -


i getting error when using syntheticablackmoonlookandfeel in java swing code. below code :: don't know why getting error ?

try {     uimanager.setlookandfeel(new syntheticablackmoonlookandfeel()); }catch(exception e) {     e.printstacktrace(); }

it showing me type of error : enter image description here

the solution issue specify fully-qualified name of lookandfeel class string argument uimanager.setlookandfeel() rather try pass instance of argument.

so, in case, you'd want write:

uimanager.setlookandfeel("(package).(namespace).syntheticablackmoonlookandfeel");

...where you'd replace (package) , (namespace) correct values.

it may this, i'm not 100% sure don't use theme you're referencing:

de.javasoft.plaf.synthetica.syntheticastandardlookandfeel
