并非JDK中所有的Java类都需要用到,可以将那些不需要的Java类文件以及一些文档性的东西删除掉
删除运行程序并不需要的文档文件及目录 jdk1.8.0_161/javafx-src.zip jdk1.8.0_161/src.zip jdk1.8.0_161/man jdk1.8.0_161/db 上述文件为文档性文件,在运行程序时并不需要,可以直接删除掉. 删除运行程序并不需要的jar包,文件及目录 jdk1.8.0_161/lib/missioncontrol jdk1.8.0_161/lib/visualvm jdk1.8.0_161/lib/ant-javafx.jar jdk1.8.0_161/lib/javafx-mx.jar jdk1.8.0_161/lib/jconsole.jar jdk1.8.0_161/jre/lib/amd64/libawt_xawt.so jdk1.8.0_161/jre/lib/amd64/libjavafx_font_freetype.so jdk1.8.0_161/jre/lib/amd64/libjavafx_font_pango.so jdk1.8.0_161/jre/lib/amd64/libjavafx_font.so jdk1.8.0_161/jre/lib/amd64/libjavafx_font_t2k.so jdk1.8.0_161/jre/lib/amd64/libjavafx_iio.so jdk1.8.0_161/jre/lib/amd64/libjfxwebkit.so jdk1.8.0_161/jre/lib/desktop jdk1.8.0_161/jre/lib/ext/jfxrt.jar jdk1.8.0_161/jre/lib/fonts jdk1.8.0_161/jre/lib/locale/de jdk1.8.0_161/jre/lib/locale/fr jdk1.8.0_161/jre/lib/locale/it jdk1.8.0_161/jre/lib/locale/ja jdk1.8.0_161/jre/lib/locale/ko jdk1.8.0_161/jre/lib/locale/ko.UTF-8 jdk1.8.0_161/jre/lib/locale/pt_BR jdk1.8.0_161/jre/lib/locale/sv jdk1.8.0_161/jre/lib/locale/zh_HK.BIG5HK jdk1.8.0_161/jre/lib/locale/zh_TW jdk1.8.0_161/jre/lib/locale/zh_TW.BIG5 jdk1.8.0_161/jre/lib/oblique-fonts jdk1.8.0_161/jre/lib/deploy.jar jdk1.8.0_161/jre/lib/locale/ 删除jar包中不需要的Java类包 jdk1.8.0_161/jre/lib/charsets.jar/sun/awt jdk1.8.0_161/jre/lib/resources.jar/javax/swing jdk1.8.0_161/jre/lib/rt.jar/com/sun/awt jdk1.8.0_161/jre/lib/rt.jar/com/sun/java/swing jdk1.8.0_161/jre/lib/rt.jar/com/sun/swing jdk1.8.0_161/jre/lib/rt.jar/java/applet jdk1.8.0_161/jre/lib/rt.jar/java/awt jdk1.8.0_161/jre/lib/rt.jar/javax/swing jdk1.8.0_161/jre/lib/rt.jar/sun/applet jdk1.8.0_161/jre/lib/rt.jar/sun/awt jdk1.8.0_161/jre/lib/rt.jar/sun/java2d jdk1.8.0_161/jre/lib/rt.jar/sun/swing
