Java反射類成員變量

Java反射類成員變量代碼如下：

1. package com.test;
3. import java.lang.reflect.Field;
4. import java.lang.reflect.Modifier;
6. public class Test_5 {
8. public static final int a = 111;
9. public static final int b = 222;
10. public static final int c = 333;
11. public static final int d = 444;
13. public static void main(String[] args) {
14. try {
15. Class c = Class.forName("com.test.Test_5");
16. Field[] fields = c.getDeclaredFields();
17. for (int i = 0; i < fields.length; i++) {
18. String m = Modifier.toString(fields[i].getModifiers());
19. if (m != null && m.indexOf("final") > -1) {
20. System.out.println(fields[i].getInt(int.class));
21. }
22. }
23. } catch (ClassNotFoundException e) {
24. e.printStackTrace();
25. } catch (IllegalArgumentException e) {
26. e.printStackTrace();
27. } catch (IllegalAccessException e) {
28. e.printStackTrace();
29. }
31. }
32. }
