java的System.getProperty()方法可以獲取的值。

獲取的程式碼示例：

1. publicclass SystemProperty {  
2.     publicstaticvoid 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"));     
37. }
