java的System.getProperty()方法可以获取的值

 1 public class SystemProperty {
 2     public static void main(String args[]) {   
 3     System.out.println("java_vendor:" + System.getProperty("java.vendor"));   
 4     System.out.println("java_vendor_url:"   
 5              + System.getProperty("java.vendor.url"));   
 6     System.out.println("java_home:" + System.getProperty("java.home"));   
 7     System.out.println("java_class_version:"   
 8              + System.getProperty("java.class.version"));   
 9     System.out.println("java_class_path:"   
10             + System.getProperty("java.class.path"));   
11     System.out.println("os_name:" + System.getProperty("os.name"));   
12     System.out.println("os_arch:" + System.getProperty("os.arch"));   
13     System.out.println("os_version:" + System.getProperty("os.version"));   
14     System.out.println("user_name:" + System.getProperty("user.name"));   
15     System.out.println("user_home:" + System.getProperty("user.home"));   
16     System.out.println("user_dir:" + System.getProperty("user.dir"));   
17     System.out.println("java_vm_specification_version:"   
18             + System.getProperty("java.vm.specification.version"));   
19     System.out.println("java_vm_specification_vendor:"   
20             + System.getProperty("java.vm.specification.vendor"));   
21     System.out.println("java_vm_specification_name:"   
22             + System.getProperty("java.vm.specification.name"));   
23     System.out.println("java_vm_version:"   
24             + System.getProperty("java.vm.version"));   
25     System.out.println("java_vm_vendor:"   
26             + System.getProperty("java.vm.vendor"));   
27     System.out   
28             .println("java_vm_name:" + System.getProperty("java.vm.name"));   
29     System.out.println("java_ext_dirs:"   
30             + System.getProperty("java.ext.dirs"));   
31     System.out.println("file_separator:"   
32             + System.getProperty("file.separator"));   
33     System.out.println("path_separator:"   
34             + System.getProperty("path.separator"));   
35     System.out.println("line_separator:"   
36             + System.getProperty("line.separator"));
