Question

我在我的java项目中使用netbeans，我想在我的项目中添加synthetica外观。

这是我设置Synthetica外观的代码

public static void main(String[] args) {
        MainFrame mf = new MainFrame();    

    try{
        UIManager.setLookAndFeel(new SyntheticaSilverMoonLookAndFeel());
        mf.setVisible(true);
        mf.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
    }catch(Exception e){
        System.out.println(e);
    }
}

我已将synthetica.jar和syntheticaSilverMoon.jar添加到我的库中。

但是，当我试图运行该项目时，它给了我

我的代码有什么问题？需要帮助。

这个问题似乎重复，看起来你正在使用不支持最新JDK的旧版Synthetica。请下载支持最新JDK的最新Synthetica＆gt; 7.您可以在这里参考这个question
