How to get protected method ?

I thought i can get protected method of my class when calling a Class.getMethod(String, Class []) in another class which inside the same package. However, it seem that i can't do that because it throw me a NoSuchMethodException when the method was protected. I thought all classes in same package can access the protected methods or fields of each other ??? Why ?
So, how i'm able to get the protected method in runtime ? (Hopefully no need to do anything with the SecurityManager)

It is working
Pls try the following program ...
public class p1 {
public static void main(String as[]) {
p2 ps2 = new p2();
ps2.abc();
class p2 {
protected void abc() {
System.out.println("Hello");

How to get protected fields

Hello,
I don't know how to get protected fields that a class inherits from its superclass through reflexion ... the getDeclaredFields method seems not working ...
here is my test program:
import java.io.File;
import java.lang.reflect.Field;
public class Test {
     public static void main(String[] args) {
          Field [] fieldList = SubClass.class.getDeclaredFields();
          for (Field field: fieldList) {
               field.setAccessible(true);
               System.out.println (field.getName());
     static class SuperClass {
          protected File file;
          public SuperClass () {
               file = new File ("a.txt");
     static class SubClass {
          private File myfile;
          public SubClass () {
               myfile = new File ("b.txt");
The output is
myfile
This means, the getDeclaredField method of the SubClass returns only fields declared by this class, not protected fields declared by its superclass.
Anyone has an idea to fix the problem, please help me. Thank you a lot
}

That's not a problem, the documentation specifically says that getDeclaredFields() only returns fields from this class. If you want fields from the superclass, why not just getSuperclass().getDeclaredFields()?

How to use protected method in jsp code

Could anyone tell me how to use protected method in jsp code ...
I declare a Calendar class , and I want to use the isTimeSet method ,
But if I write the code as follows ..
========================================================
<%
Calendar create_date = Calendar.getInstance();
if (create_date.isTimeSet) System.out.println("true");
%>
============================================================
when I run this jsp , it appears the error wirtten "isTimeSet has protected access in java.util.Calendar"

The only way to access a protected variable is to subclass.
MyCalendar extends Calendar
but I doubt you need to do this. If you only want to tell if a Calendar object has a time associated with it, try using
cal.isSet( Calendar.HOUR );

How to use protected method of a class in application

Hi,
will u please tell me how to use protected method of class in application. (class:cl_gui_textcontrol, method:limit_text)
Thanks in advance,
Praba.

Hi Prabha,
You can set the maximum number of characters in a textedit control in the CREATE OBJECT statement itself.
Just see the first parameter in the method . I mean MAX_NUMBER_CHARS. Just set that value to the required number.
Eg:
data: edit type ref to CL_GUI_TEXTEDIT.
create object edit
exporting
    MAX_NUMBER_CHARS       = 10
   STYLE                  = 0
   WORDWRAP_MODE          = WORDWRAP_AT_WINDOWBORDER
   WORDWRAP_POSITION      = -1
   WORDWRAP_TO_LINEBREAK_MODE = FALSE
   FILEDROP_MODE          = DROPFILE_EVENT_OFF
    parent                 = OBJ_CUSTOM_CONTAINER
   LIFETIME               =
   NAME                   =
EXCEPTIONS
    ERROR_CNTL_CREATE      = 1
    ERROR_CNTL_INIT        = 2
    ERROR_CNTL_LINK        = 3
    ERROR_DP_CREATE        = 4
    GUI_TYPE_NOT_SUPPORTED = 5
    others                 = 6
IF sy-subrc <> 0.
MESSAGE ID SY-MSGID TYPE SY-MSGTY NUMBER SY-MSGNO
           WITH SY-MSGV1 SY-MSGV2 SY-MSGV3 SY-MSGV4.
ENDIF.
In this case, the max: number of characters will be set to 10.
I hope your query is solved.
Regards,
SP.

Not sure how to use protected method in arraylisy

Hi,
Im wondering how to use the removeRange method in java arraylist, its a protected method which returns void.
http://java.sun.com/j2se/1.3/docs/api/java/util/ArrayList.html#removeRange(int,%20int)
So if my class extends Arraylist i should be able to call the method but the compiler states that it still has protected access in arraylist. Does this mean im still overriding the method in arraylist ? A little explanation of whats happeneing would be appreciated as much as an answer
thanks

In this codefinal class myClass extends java.util.ArrayList {
    private ArrayList array = new ArrayList();
    public myClass(ArrayList ary){
        for(int i=0;i<7;i++) {
            array.add(ary.get(i));
        ary.removeRange(0,7)
}You are defining a class called myClass which extends ArrayList.
You have a member variable called array which is an ArrayList
You have a constructor which takes a parameter called ary which is an ArrayList
Since ary is an ArrayList, you cannot call it's removeRange() method unless myClass is in the java.util package. Do not put your class in the java.util package.
It seems like what you want to do is to move the items in one ArrayList to another ArrayList rather than copying them. I wrote a program to do this. Here it isimport java.util.*;
public class Test3 {
public static void main(String[] args) {
    MyClass myClass = new MyClass();
    for (int i=0; i<5; i++) myClass.add("Item-"+i);
    System.out.println("------ myClass loaded -------");
    for (int i=0; i<myClass.size(); i++) System.out.println(myClass.get(i));
    MyClass newClass = new MyClass(myClass);
    System.out.println("------ newClass created -------");
    for (int i=0; i<newClass.size(); i++) System.out.println(newClass.get(i));
    System.out.println("------ myClass now contains -------");
    for (int i=0; i<myClass.size(); i++) System.out.println(myClass.get(i));
class MyClass extends java.util.ArrayList {
    public MyClass() {}
    public MyClass(MyClass ary){
        for(int i=0;i<ary.size();i++) add(ary.get(i));
        ary.removeRange(0,ary.size());
}You should notice now that I don't create an ArrayList anywhere. Everything is a MyClass. By the way, class names are normally capitalized, variable names are not. Hence this line
MyClass myClass = new MyClass();
In the code above I create an empty MyClass and then populate it with 5 items and then print that list. Then I create a new MyClass using the constructor which takes a MyClass parameter. This copies the items from the parameter list into the newly created MyClass (which is an ArrayList) and then removes the items from the MyClass passed as a parameter. Back in the main() method, I then print the contents of the two MyClass objects.
One thing which may be a little confusing is this line.
for(int i=0;i<ary.size();i++) add(ary.get(i));
the add() call doesn't refer to anything. What it really refers to is the newly created MyClass object which this constructor is building. This newly created object is the 'this' object. So the line above could be rewritten as
for(int i=0;i<ary.size();i++) this.add(ary.get(i));
Hopefully this helps a little. The problems you seem to be having are associated with object oriented concepts. You might try reading this

How to use protected method of a particular class described in API

I read in some forum that for accessing protected method reflcetion should be used. If I'm not wrong then how can I use reflection to access such methods and if reflection isn't the only way then what is another alternative. Please help me...
regards,
Jay

I read in some forum that for accessing protected
method reflcetion should be used. If I'm not wrong
then how can I use reflection to access such methods
and if reflection isn't the only way then what is
another alternative. Please help me...Two ways:
- either extend that class
- or don't use it at all
If you use reflection, you're very likely to break something. And not only the design. Remember that the method is supposed to be inaccessible for outside classes.

How to Access Protected Method of a Class

Hi,
I need to access a Protected method (ADOPT_LAYOUT) of class CL_REIS_VIEW_DEFAULT.
If i try to call that method by using class Instance it is giving error as no access to protected class. Is there any other way to access it..

Hi,
You can create a sub-class of this class CL_REIS_VIEW_DEFAULT, add a new method which is in public section and call the method ADOPT_LAYOUT of the super-class in the new method. Now you can create an instance of the sub-class and call the new sub-class method.
REPORT ZCD_TEST.
class sub_class definition inheriting from CL_REIS_VIEW_DEFAULT.
public section.
methods: meth1 changing cs_layout type LVC_S_LAYO.
endclass.
class sub_class implementation.
method meth1.
call method ADOPT_LAYOUT changing CS_LAYOUT = cs_layout.
endmethod.
endclass.
data: cref type ref to sub_class.
data: v_layout type LVC_S_LAYO.
start-of-selection.
create object cref.
call method cref->meth1 changing cs_layout = v_layout.

How to get subclass method in an inheritance?

I just need to know how to cast a class dynamically
at runtime instead of manual casting it like:
Cat cat = new Cat();This is not a cast. Why do you mean?

How to get a method to call the correct passed object in the constructor

I have 2 constructors for a certain object:
public class ABC{
//variables
private DEF def;
private GHI ghi;
public ABC(DEF def){
this.def = def;
someMethod();
public ABC(GHI ghi){
this.ghi = ghi;
someMethod();
}Now, this someMethod() references / calls a method from the 2 classes passed in the constructor say def.getSome() and ghi.getSome().
Depending on which constructor is used, it should call the respective xxx.getSome(). Do I need to write 2 someMethod()s or is there a way that one method will call the proper xxx.getSome() ?
Thanks.....

Hi
Following the example may be help to you call correct method,
// Interface QuizMaster
public interface QuizMaster {
     public String popQuestion();
// Class StrutsQuizMaster
public class StrutsQuizMaster implements QuizMaster{
     public String popQuestion() {
          return "Are you new to Struts?";
// Class SpringQuizMaster
public class SpringQuizMaster implements QuizMaster{
     public String popQuestion() {
          return "Are you new to Spring?";
// Class QuizMasterService
public class QuizMasterService {
     QuizMaster quizMaster;
     public QuizMasterService(SpringQuizMaster quizMaster){
          this.quizMaster = quizMaster;
     public QuizMasterService(StrutsQuizMaster quizMaster){
          this.quizMaster = quizMaster;
     public void askQuestion()
          System.out.println(quizMaster.popQuestion());
// QuizProgram
public class QuizProgram {
     public static void main(String[] args) {
          // Option : 1
// StrutsQuizMaster quizMaster = new StrutsQuizMaster();
// Option : 2
SpringQuizMaster quizMaster = new SpringQuizMaster();
          QuizMasterService quizMasterService = new QuizMasterService(quizMaster);
          quizMasterService.askQuestion();
here you can create object of StrutsQuizMaster or SpringQuizMaster and pass into the QuizMasterService object constructor, base on the object correct method will be called.

The problem is i dont have a method to get row ids if user select multiple rows...
I tried using GET_ROW_ID but as its a protected method i cant use it..
please suggest stepwise how to use protected method in my class...and if u coud suggest some public method it will be great
regards
vivek

Hi,
You can also use the FM "REUSE_ALV_POPUP_TO_SELECT'.
It displays the output along with check boxes, where u can select the rows whatever u want.
Thanks & Regards,

please advise.

Jafar,
You need to Take the Help of DATA_CHANGED event, when ever there is a change in the Grid, it will trigger, here you can capture the Cells which are modified.
in your PAI call the method check changed data
CL_GUI_ALV_GRID-->CHECK_CHANGED_DATA
You need to set the handler for datachanged.
set the handler for this, and register the event modified or enter.
**Handler to Check the Data Change
    HANDLE_DATA_CHANGED FOR EVENT DATA_CHANGED
                         OF CL_GUI_ALV_GRID
                         IMPORTING ER_DATA_CHANGED
                                   E_ONF4
                                   E_ONF4_BEFORE
                                   E_ONF4_AFTER,
**Handle Data Change
METHOD HANDLE_DATA_CHANGED.
DATA: X_CHANGE TYPE LVC_S_MODI. "modified cells
    LOOP AT ER_DATA_CHANGED->MT_GOOD_CELLS INTO X_CHANGE.
    ENDLOOP.
ENDMETHOD.                    "HANDLE_DATA_CHANGED

How to get selection criteria value in method IF_POWL_FEEDER~HANDLE_ACTION

hi:
As you know, we could get the leading selected POWL result data through parameter c_selected and c_selected in this method.
but moreever, I want to get the selection criterai values in this method too just like the paramter i_selcrit_values in the method IF_POWL_FEEDER~GET_OBJECTS, how to do it?
I have tried to define a attribute in my POWL class and save i_selcrit_values into this attribute in the method IF_POWL_FEEDERGET_OBJECTS, but in method IF_POWL_FEEDERHANDLE_ACTION, this attribute is still empty, so this workaround failed.
thanks.

hi guys:
I have founded how to do it:
METHOD get_selcrit.
DATA ls_query TYPE powl_query_sty.
DATA lt_selcrit TYPE rsparams_tt.
FIELD-SYMBOLS <ls_selcrit> LIKE LINE OF lt_selcrit.
CALL METHOD cl_powl_runtime_services=>get_current_query
    RECEIVING
      rs_query = ls_query.
CALL METHOD cl_powl_query_accessor=>get_cached_selcrit
    EXPORTING
      i_query     = ls_query-query
    IMPORTING
      e_crit_para = lt_selcrit.
READ TABLE lt_selcrit WITH KEY selname = iv_selname
    ASSIGNING <ls_selcrit>.
IF <ls_selcrit> IS ASSIGNED.
    ev_selcrit = <ls_selcrit>-low.
ENDIF.
ENDMETHOD.
