    获取JRE系统相关参数

    java 通过System.getProperties()获取系统参数

     Properties props=System.getProperties(); //系统属性

    //   Set<Object> keySet = sysProperty.keySet();

    //   for (Object object : keySet) {

    //    String property = sysProperty.getProperty(object.toString());

    //    System.out.println(object.toString()+" : "+property);

    //   }

      System.out.println("Java的运行环境版本:"+props.getProperty("java.version"));

      System.out.println("Java的运行环境供应商:"+props.getProperty("java.vendor"));

      System.out.println("Java供应商的URL:"+props.getProperty("java.vendor.url"));

      System.out.println("Java的安装路径:"+props.getProperty("java.home"));

      System.out.println("Java的虚拟机规范版本:"+props.getProperty("java.vm.specification.version"));

      System.out.println("Java的虚拟机规范供应商:"+props.getProperty("java.vm.specification.vendor"));

      System.out.println("Java的虚拟机规范名称:"+props.getProperty("java.vm.specification.name"));

      System.out.println("Java的虚拟机实现版本:"+props.getProperty("java.vm.version"));

      System.out.println("Java的虚拟机实现供应商:"+props.getProperty("java.vm.vendor"));

      System.out.println("Java的虚拟机实现名称:"+props.getProperty("java.vm.name"));

      System.out.println("Java运行时环境规范版本:"+props.getProperty("java.specification.version"));

      System.out.println("Java运行时环境规范供应商:"+props.getProperty("java.specification.vender"));

      System.out.println("Java运行时环境规范名称:"+props.getProperty("java.specification.name"));

      System.out.println("Java的类格式版本号:"+props.getProperty("java.class.version"));

      System.out.println("Java的类路径:"+props.getProperty("java.class.path"));

      System.out.println("加载库时搜索的路径列表:"+props.getProperty("java.library.path"));

      System.out.println("默认的临时文件路径:"+props.getProperty("java.io.tmpdir"));

      System.out.println("一个或多个扩展目录的路径:"+props.getProperty("java.ext.dirs"));

      System.out.println("操作系统的名称:"+props.getProperty("os.name"));

      System.out.println("操作系统的构架:"+props.getProperty("os.arch"));

      System.out.println("操作系统的版本:"+props.getProperty("os.version"));

      System.out.println("文件分隔符:"+props.getProperty("file.separator"));   //在 unix 系统中是"/"

      System.out.println("路径分隔符:"+props.getProperty("path.separator"));   //在 unix 系统中是":"

      System.out.println("行分隔符:"+props.getProperty("line.separator"));   //在 unix 系统中是"/n"

      System.out.println("用户的账户名称:"+props.getProperty("user.name"));

      System.out.println("用户的主目录:"+props.getProperty("user.home"));

      System.out.println("用户的当前工作目录:"+props.getProperty("user.dir"));
