java的System.getProperty()方法能够获取的值

获取的代码演示样例：

public class SystemProperty { public static void main(String args[]) { System.out.println("java_vendor:" + System.getProperty("java.vendor")); System.out.println("java_vendor_url:" + System.getProperty("java.vendor.url")); System.out.println("java_home:" + System.getProperty("java.home")); System.out.println("java_class_version:" + System.getProperty("java.class.version")); System.out.println("java_class_path:" + System.getProperty("java.class.path")); System.out.println("os_name:" + System.getProperty("os.name")); System.out.println("os_arch:" + System.getProperty("os.arch")); System.out.println("os_version:" + System.getProperty("os.version")); System.out.println("user_name:" + System.getProperty("user.name")); System.out.println("user_home:" + System.getProperty("user.home")); System.out.println("user_dir:" + System.getProperty("user.dir")); System.out.println("java_vm_specification_version:" + System.getProperty("java.vm.specification.version")); System.out.println("java_vm_specification_vendor:" + System.getProperty("java.vm.specification.vendor")); System.out.println("java_vm_specification_name:" + System.getProperty("java.vm.specification.name")); System.out.println("java_vm_version:" + System.getProperty("java.vm.version")); System.out.println("java_vm_vendor:" + System.getProperty("java.vm.vendor")); System.out .println("java_vm_name:" + System.getProperty("java.vm.name")); System.out.println("java_ext_dirs:" + System.getProperty("java.ext.dirs")); System.out.println("file_separator:" + System.getProperty("file.separator")); System.out.println("path_separator:" + System.getProperty("path.separator")); System.out.println("line_separator:" + System.getProperty("line.separator")); }
