Application of Java reflection mechanism

1. // Set data through the Reflection Method
2. For (INT I = 0; I <grade_num; I ++ ){
3. Method1 = getvaluemethod. setmethod (New fr0313dto (),
4. "Minoritystunum" + (I + 1 ),
5. New Class [] {string. Class });
6. Method2 = getvaluemethod. setmethod (New fr0313dto (),
7. "Girlstunum" + (I + 1 ),
8. New Class [] {string. Class });
9. Method3 = getvaluemethod. setmethod (New fr0313dto (),
10. "Stunum" + (I + 1), new class [] {string. Class });
11. Try {
12. Method1.invoke (DTO, new object [] {string
13. . Valueof (minoritystunum )});
14. Method2.invoke (DTO, new object [] {string
15. . Valueof (getintvalue (acadgirlmap
16. . Get (gradeacadyear [I])});
17. Method3.invoke (DTO, new object [] {string
18. . Valueof (getintvalue (acadstumap
19. . Get (gradeacadyear [I])});
20. } Catch (illegalargumentexception e ){
21. Log. Error (E );
22. } Catch (illegalaccessexception e ){
23. Log. Error (E );
24. } Catch (invocationtargetexception e ){
25. Log. Error (E );
26. }
27. }

The following describes how to assemble the set method. setmethod in getvaluemethod

1. Public static method setmethod (Object object, string propertyname,
2. Class [] partypes ){
3. If (propertyname = NULL | propertyname. Length () = 0 ){
4. Return NULL;
5. }
6. String propertynameupper = propertyname. substring (0, 1). touppercase ()
7. + Propertyname. substring (1 );
9. String methodname = "set" + propertynameupper;
10. Method method = NULL;
11. Try {
12. Method = object. getclass (). getmethod (methodname, partypes );
13. } Catch (securityexception e ){
14. E. printstacktrace ();
15. } Catch (nosuchmethodexception e ){
16. E. printstacktrace ();
17. }
18. Return method;
19. }
