2.将下列代码添加到你的程序的主执行类的main()方法中：
try {
UIManager.setLookAndFeel(new SubstanceLookAndFeel());
JFrame.setDefaultLookAndFeelDecorated(true);
JDialog.setDefaultLookAndFeelDecorated(true);
SubstanceLookAndFeel.setCurrentTheme(new SubstanceTerracottaTheme());
// SubstanceLookAndFeel.setSkin(new EmeraldDuskSkin());
// SubstanceLookAndFeel.setCurrentButtonShaper(new ClassicButtonShaper());
// SubstanceLookAndFeel.setCurrentWatermark(new SubstanceBubblesWatermark());
// SubstanceLookAndFeel.setCurrentBorderPainter(new StandardBorderPainter());
// SubstanceLookAndFeel.setCurrentGradientPainter(new StandardGradientPainter());
// SubstanceLookAndFeel.setCurrentTitlePainter(new FlatTitePainter());
} catch (Exception e) {
System.err.println("Something went wrong!");
}
这个地方主要介绍一下关于使用substance.jar包装程序时对界面效果的几个方面的设置，主要要主题，皮肤，按钮类型，水印，边框渲染，渐变渲染与标题栏渲染．
共有22种皮肤，69种主题。
1. 下载下来substance.jar包后，解压JAR文件，可以看到在“org/jvnet/substance/skin”下有下面这些皮肤（以LookAndFeel.class结尾的文件）。
SubstanceAutumnLookAndFeel.class
SubstanceBusinessBlackSteelLookAndFeel.class
SubstanceBusinessBlueSteelLookAndFeel.class
SubstanceBusinessLookAndFeel.class
SubstanceChallengerDeepLookAndFeel.class
SubstanceCremeLookAndFeel.class
SubstanceEmeraldDuskLookAndFeel.class
SubstanceFieldOfWheatLookAndFeel.class
SubstanceGreenMagicLookAndFeel.class
SubstanceMagmaLookAndFeel.class
SubstanceMangoLookAndFeel.class
SubstanceMistAquaLookAndFeel.class
SubstanceMistSilverLookAndFeel.class
SubstanceModerateLookAndFeel.class
SubstanceNebulaBrickWallLookAndFeel.class
SubstanceNebulaLookAndFeel.class
SubstanceOfficeBlue2007LookAndFeel.class
SubstanceOfficeSilver2007LookAndFeel.class
SubstanceRavenGraphiteGlassLookAndFeel.class
SubstanceRavenGraphiteLookAndFeel.class
SubstanceRavenLookAndFeel.class
SubstanceSaharaLookAndFeel.class
要使用上述皮肤很简单，只要在main函数中调用下面代码即可：
//主要设置皮肤、主题还有按钮、水印、选项卡、滑动条以及水印等
//UIManager.setLookAndFeel("org.jvnet.substance.skin.SubstanceBusinessLookAndFeel");
//UIManager.setLookAndFeel("org.jvnet.substance.skin.SubstanceOfficeSilver2007LookAndFeel");
//UIManager.setLookAndFeel("org.jvnet.substance.skin.SubstanceSaharaLookAndFeel");
//UIManager.setLookAndFeel("org.jvnet.substance.skin.SubstanceOfficeBlue2007LookAndFeel");
UIManager.setLookAndFeel("org.jvnet.substance.skin.SubstanceBusinessBlackSteelLookAndFeel");
2. org/jvnet/substance/theme 下有所有可用的主题：
SubstanceAquaTheme.class
SubstanceBarbyPinkTheme.class
SubstanceBlendBiTheme.class
SubstanceBottleGreenTheme.class
SubstanceBrownTheme.class
SubstanceCharcoalTheme.class
SubstanceColorBlindTheme.class
SubstanceComplexTheme.class

SubstanceEbonyTheme.class
SubstanceHueShiftTheme.class
SubstanceInvertedTheme.class
SubstanceJadeForestTheme.class
SubstanceLightAquaTheme.class
SubstanceLimeGreenTheme.class
SubstanceMixBiTheme.class
SubstanceMixTheme.class
SubstanceNegatedTheme.class
SubstanceOliveTheme.class
SubstanceOrangeTheme.class
SubstanceProtanopiaTheme.class
SubstancePurpleTheme.class
SubstanceRaspberryTheme.class
SubstanceSaturatedTheme.class
SubstanceSepiaTheme.class
SubstanceShadeTheme.class
SubstanceSteelBlueTheme.class
SubstanceSunGlareTheme.class
SubstanceSunsetTheme.class
SubstanceTerracottaTheme.class
SubstanceTheme$1$1.class
SubstanceTheme$1.class
SubstanceTheme$10.class
SubstanceTheme$11.class

SubstanceTheme$24.class
SubstanceTheme$25.class
SubstanceTheme$26.class
SubstanceTheme$27.class
SubstanceTheme$28.class
SubstanceTheme$3.class
SubstanceTheme$4.class
SubstanceTheme$5.class
SubstanceTheme$6.class

SubstanceTheme$9.class
SubstanceTheme$ThemeKind.class
SubstanceTheme.class
SubstanceTintTheme.class
SubstanceToneTheme.class
SubstanceTritanopiaTheme.class
SubstanceUltramarineTheme.class
SubstanceWrapperTheme.class
改变界面的默认主题也很简单，只需要加上以下代码就可以了（不过貌似5.0以上没有这个方法了，且substance下也没有theme文件夹了）。另外5.0版本以上必须将这些语句置于
java.awt.EventQueue.invokeLater(new Runnable() {
public void run() {
//此处设置皮肤和主题
});
的run方法中，否则会出错。
SubstanceLookAndFeel.setCurrentTheme("org.jvnet.substance.theme.SubstanceDarkVioletTheme");
另外如果想让整体界面变得协调，最好设置容器窗体的DefaultLookAndFeelDecorated属性为true。
JFrame.setDefaultLookAndFeelDecorated(true);
JDialog.setDefaultLookAndFeelDecorated(true);
当然除了设置皮肤和主题外，还可以设置按钮、水印、选项卡、滑动条以及水印、字体、标题等的观感。具体的可以查看substanceorgjvnetsubstance目录。方法同上面讲的一样。
