public class SystemDemo02{
public static void main(String args[]){
System.getProperties().list(System.out) ; // 列出系統的全部屬性
}
};此處取得的是全部的屬性，如果現在只需要取幾個固定屬性的話，則就可以通過以下取得：-- listing properties -- java.runtime.name=Java(TM) SE Runtime Environment sun.boot.library.path=D:\MyEclipse_anzhuang\binary\com.sun.... java.vm.version=11.3-b02 java.vm.vendor=Sun Microsystems Inc. java.vendor.url=http://java.sun.com/ path.separator=; java.vm.name=Java HotSpot(TM) Client VM file.encoding.pkg=sun.io user.country=CN sun.java.launcher=SUN_STANDARD sun.os.patch.level= java.vm.specification.name=Java Virtual Machine Specification user.dir=C:\Users\Administrator\Desktop\myEcli... java.runtime.version=1.6.0_13-b03 java.awt.graphicsenv=sun.awt.Win32GraphicsEnvironment java.endorsed.dirs=D:\MyEclipse_anzhuang\binary\com.sun.... os.arch=x86 java.io.tmpdir=C:\Users\ADMINI~1\AppData\Local\Temp\ line.separator= java.vm.specification.vendor=Sun Microsystems Inc. user.variant= os.name=Windows Vista sun.jnu.encoding=GBK java.library.path=D:\MyEclipse_anzhuang\binary\com.sun.... java.specification.name=Java Platform API Specification java.class.version=50.0 sun.management.compiler=HotSpot Client Compiler os.version=6.2 user.home=C:\Users\Administrator user.timezone= java.awt.printerjob=sun.awt.windows.WPrinterJob file.encoding=GBK java.specification.version=1.6 user.name=Administrator java.class.path=C:\Users\Administrator\Desktop\myEcli... java.vm.specification.version=1.0 sun.arch.data.model=32 java.home=D:\MyEclipse_anzhuang\binary\com.sun.... java.specification.vendor=Sun Microsystems Inc. user.language=zh awt.toolkit=sun.awt.windows.WToolkit java.vm.info=mixed mode java.version=1.6.0_13 java.ext.dirs=D:\MyEclipse_anzhuang\binary\com.sun.... sun.boot.class.path=D:\MyEclipse_anzhuang\binary\com.sun.... java.vendor=Sun Microsystems Inc. file.separator=\ java.vendor.url.bug=http://java.sun.com/cgi-bin/bugreport... sun.cpu.endian=little sun.io.unicode.encoding=UnicodeLittle sun.desktop=windows sun.cpu.isalist=pentium_pro+mmx pentium_pro pentium+m...
