java - How to execute selected methods of a given class -

for example,

class {      @test      public int add()     {     ....     }     @test      public int sub()     {     ....     }     @test      public int div()     {     ....     }      @testnew      public void mul()     {     ....     } } 

consider class named a..in class have annotated methods , want display methods has annotation @test. can done using java reflection's getannotation() methods. i'm getting proper output this. i've list of @test annotated methods displayed in jsp page precede checkbox each , every entry of output.

for example:

        int add()   [*]          int sub()   [*]          int div()   []                   [execute] 

consider square brackets checkboxes.

[*] -->selected checkbox.. [ ] -->not selected checkbox... 

now,i want execute selected check box methods , display result. need generate xml files selected methods know much. don't know how can generate xml files selected methods result of selected methods.

once select checkbox , click on [execute] button ,result of selected methods should displayed.

how can ?

using reflection

class<?> c = class.forname("a"); method  method = c.getdeclaredmethod("add", parametertypes) method.invoke (objecttoinvokeon, params)
