Method/Class of the day.

So I was thinking as I was reading my word of the day email that I get from Merriam webster, you know wouldn't it be a great Idea to get get a method or class of the day email from the Java class libraries here at sun?
I know that alot of the words I get from my word of the day I'll probably never use however, there are some that I do use from time to time. But Java is a language and it's always helpful to increase our vocabulary.
So I do think that this would be helpful. Are there any services that do this already?

AtomicReference
http://java.sun.com/javase/6/docs/api/java/util/concurrent/atomic/AtomicReference.html#lazySet(V)
Uh, like totally man. Could you please be more vague with the documentation?<quote>
lazySet has the memory effects of writing (assigning) a volatile variable except that it permits reorderings with subsequent (but not previous) memory actions that do not themselves impose reordering constraints with ordinary non-volatile writes. Among other usage contexts, lazySet may apply when nulling out, for the sake of garbage collection, a reference that is never accessed again.

http://java.sun.com/javase/6/docs/api/java/util/concurrent/atomic/AtomicReference.html#weakCompareAndSet(V,%20V)
It's great that they include a method that warns you "may fail spuriously - NEVER use this!", but then provide no explanation for what the method is good for and why it's even published in the API.This was no good?
<quote>
The atomic classes also support method weakCompareAndSet, which has limited applicability. On some platforms, the weak version may be more efficient than compareAndSet in the normal case, but differs in that any given invocation of the weakCompareAndSet method may return false spuriously (that is, for no apparent reason). A false return means only that the operation may be retried if desired, relying on the guarantee that repeated invocation when the variable holds expectedValue and no other thread is also attempting to set the variable will eventually succeed. (Such spurious failures may for example be due to memory contention effects that are unrelated to whether the expected and current values are equal.) Additionally weakCompareAndSet does not provide ordering guarantees that are usually needed for synchronization control. However, the method may be useful for updating counters and statistics when such updates are unrelated to the other happens-before orderings of a program. When a thread sees an update to an atomic variable caused by a weakCompareAndSet, it does not necessarily see updates to any other variables that occurred before the weakCompareAndSet. This may be acceptable when, for example, updating performance statistics, but rarely otherwise.

Useful Life in Dep Key "to the day"

Hi,
we have two depreciation areas one for IN gaap and the other for US GAAP. In GAAP has depreciation keys with "to the day" feature and the US GAAP has depreciation keys created with useful life feature.
Now the issue is since useful life has got no role in the case of IN GAAP, whenever we create asset we press enter enter and the same usefule life as per US GAAP get copied in the US GAAP also as it has no relevance for calculation.
The problem is that if i enter only period 1 as useful life for US GAAP( meaning that the asset is to be fully depreciated in one month for US GAAP purpose) and the same period 1 is entered in IN GAAP. then for IN GAAP my full asset is getting depreciated in 6 months wheras the depreciation key assigned to it is 13,91 wdv method( with to the day tick).
I changed the period 1 and made it 999 for IN GAAP purpose and tested it in test system and then system is showing correct values.
Can anyone throw some light on this issue as to why it is changing in case of useful life when the dep to the day is ticked in depreciation key.
Regards,
SAPFICO

How to find the day of the week ?

Hi,
I want to find the day of the current date. Can you please let me know as to how to get the same ?
My code is like :
java.util.Date date = new java.util.Date();
// Here i need to use a method to retrive the day of this date
Your early input is appreciated.

Use a java.util.GregorianCalendar:
GregorianCalendar calendar = new GregorianCalendar();
System.out.println("DAY_OF_WEEK: " + calendar.get(Calendar.DAY_OF_WEEK));

Hi,
Compare the data types of the fields in your table tb_lookup with the data types in your datasource. Most probably there is an inconsistency with that. One thing that I realize is that
I use the select statement in the format select ... from ... into... Maybe you need to change places of that, but I am not sure. You may put a break point and debug it with simulation.
Hope it gives an idea.

Overwriting a method of a super class in the subclass ???

Hi,
can somebody tell me whether it's possible to add a new implementation of a method in the sub class which is inherited from a super class?
I want to model my program in that way:
1. I define a super class with some implemented methods.
2. This class should be inherited in a sub class. One method should be used as it was implemented in the super class but another method should be overwritten in the subclass.
I know this concept from Java but I couldn't find a way how to do it in ABAP
Many thanks for any help!
Best regards,
Birgit

hi,
yeas you can do it,
Subclass can re-implement the inherited public and protected methods from superclass.Class C1 contains method METH1(public) and METH2(protected), both of which are modified and re-implemented in its subclass C2.also you can have ur own methods in subclass.Objects are created out of both classes and the method METH1 for both objects are called.
Output of the program demonstrates different behaviour for method METH1 of class C1 and C2.
This demonstrates the theme.

How to call a method in private section of a class in the public section

Hi Everybody,
i have written a method(meth1) in the private section of a class(C1).
it is as follows
class C1 definition.
private section.
methods: meth1 importing im_dt1 like tp1
                                         im_dt2 like tp2
                                         im_dt3 like tp3
                                         im_dt4 like tp4
                           returning value(re_dt1) like tp5.
endclass.
i have the final data that has to be displayed in internal table re_dt1.
now my question is how to call this method present in private section into public section and display the data present in re_dt1.
Thanks,
learning.abap.

Hi,
what you need is one public method being called at start-of-selection. Within this the private methods have to be called.
The question is, why has the method for reading the database tables to be private? If you have only one private method reading all database tables the public method being called at start-of-selection will only consist of a call-method statement.
This seems to be one call to much.
The logic for reading the different database tables is hidden inside the class anyway.
Is there any further logic reading the different database tables?
Have always all table to be read? If not another approach would be one private method for each database table being called by a public method deciding which table has to be read:
public section.
methods get_data returning value(re_Dt1).
private section.
methods:
get_table_a returning value(im_dt1),
get_table_b returning value(im_dt2),
get_table_c returning value(im_dt3),
get_table_d returning value(im_dt4),
combine_data importing im_dt1
                                im_dt2
                                im_dt3
                                im_dt4
                        returning value(re_dt1).
*- implementation of public method:
method get_data.

           lt_dt2,

                                       i_dt2 = lt_dt2
                                       i_dt3 = lt_dt3

To access a method frm a class derived frm a base class with the same name

Here' s an example:-
class TestA {
public void start() {
System.out.println("TestA");
class TestB extends TestA {
public void start() {
System.out.println("TestB");
}In main method I do this:-
TestA testA = new TestA();
TestB testB = new TestB();
((TestA)testB).start();Output :-
TestB.
Now when i define the method as static :-
class TestA {
public static void start() {
System.out.println("TestA");
class TestB extends TestA {
public static void start() {
System.out.println("TestB");
}Then output is :-
TestA.
Can anyone let me know that when i say ((TestA)testB).start(); i.e i am type casting TestB obect to it base call then TestA should be printed but it doesn't print but when i declare method as static is does print TestA.
Thanks,
Heena

>
>
Secondly, when i say ((TestA).testB).start(); output is TestB. But when i define start() method as static output is TestA. I need clarity for the same.In the static case, all that the compiler is interested in is the class of the expression before the ".". Because you've put in an explicit cast the type of expression is assumed to be TestA the compiler doesn't know what kind of object will actually be referenced at runtime. In the static case which method is called is determined at compile time.
In the instance method case what determines the method called is determined the class of the actual, run time, value of the expression, and despite your cast, the actual value is still a reference to a TestB instance, so the TestB method is called. In the instance case which method called is determined at run time.

How to determine the Class of a static methods class?

hi,
is there a way to get the code below to output
foo() called on One.class
foo() called on Two.classthanks,
asjf
public class Two extends One {
   public static void main(String [] arg) {
      One.foo(); // should say "foo() called on One.class"
      Two.foo(); // should say "foo() called on Two.class"
class One {
   public static final void foo() {
      System.out.println("foo() called on "/*+something.getClass()*/);
}

- One.class won't resolve to Two.class when the static
method is called via the class TwoThat's because static methods are not polymorphic. They cannot be overridden. For example try this:
public class Two extends One {
   public static void main(String [] arg) {
      One.foo(); // should say "foo() called on One.class"
      Two.foo(); // should say "foo() called on Two.class"
      One one = new Two();
      one.foo();
      ((Two) one).foo();
   public static void foo() {
      System.out.println("foo() called on Two");
class One {
   public static void foo() {
      System.out.println("foo() called on One");
}

How to override a method in an inner class of the super class

I have a rather horribly written class, which I need to adapt. I could simply do this if I could override a method in one of it's inner classes. My plan then was to extend the original class, and override the method in question. But here I am struggling.
The code below is representative of my situation.
public class ClassA
   ValueChecks vc = null;
   /** Creates a new instance of Main */
   public ClassA()
      System.out.println("ClassA Constructor");
      vc = new ValueChecks();
      vc.checkMaximum();
     // I want this to call the overridden method, but it does not, it seems to call
     // the method in this class. probably because vc belongs to this class
      this.vc.checkMinimum();
      this.myMethod();
   protected void myMethod()
      System.out.println("myMethod(SUPER)");
   protected class ValueChecks
      protected boolean checkMinimum()
         System.out.println("ValueChecks.checkMinimum (SUPER)");
         return true;
      protected boolean checkMaximum()
         return false;
}I have extended ClassA, call it ClassASub, and it is this Class which I instantiate. The constructor in ClassASub obviously calls the constructor in ClassA. I want to override the checkMinimum() method in ValueChecks, but the above code always calls the method in ClassA. The ClassASub code looks like this
public class ClassASub extends ClassA
   public ClassAInner cias;
   /** Creates a new instance of Main */
   public ClassASub()
      System.out.println("ClassASub Constructor");
   protected void myMethod()
      System.out.println("myMethod(SUB)");
   protected class ValueChecks extends ClassA.ValueChecks
      protected boolean checkMinimum()
         System.out.println("ValueChecks.checkMinimum (SUB)");
         return true;
}The method myMethod seems to be suitably overridden, but I cannot override the checkMinimum() method.
I think this is a stupid problem to do with how the ValueChecks class is instantiated. I think I need to create an instance of ValueChecks in ClassASub, and pass a reference to it into ClassA. But this will upset the way ClassA works. Could somebody enlighten me please.

vc = new ValueChecks();vc is a ValueChecks object. No matter whether you subclass ValueChecks or not, vc is always of this type, per this line of code.
// I want this to call the overridden method, but it does not, it seems to > call
// the method in this class. probably because vc belongs to this class
this.vc.checkMinimum();No, it's because again vc references a ValueChecks object, because it was created as such.
And when I say ValueChecks, I mean the original class, not the one you tried to create by the same name, attempting to override the original.

The class of the deferred-methods return type "{0}" can not be found.

I am developing a multilingual portal application.
I have the method that changes the locale based on user's choice in the bean and the method is being referred to as below.
<af:selectOneChoice label="Select Language" autoSubmit="true"
value="#{localeBean.locale}"
valueChangeListener="localeBean.changeLocale">
<af:selectItem label="English" value="en" id="si1"/>
<af:selectItem label="French" value="fr" id="si2"/>
<af:selectItem label="Dutch" value="nl" id="si3"/>
</af:selectOneChoice>
when i try to run the application, i am getting compile time errors as below,
The class of the deferred-methods return type "{0}" can not be found.
No property editor found for the bean "javax.el.MethodExpression".
After going through the discussion forums i learned that the compilation errors can be resolved by setting the <jsp:directive.page deferredSyntaxAllowedAsLiteral="false> at the starting of the page.
Even after that i am getting the compilation error.
Any solutions, suggestions or possible approaches would be helpful as i am new to Webcenter Portal development.
Thanks,

The error you get points to a problem on the page (somewhere). Switch to source mode and check the right margin if you see orange or red marks. These are pointing to problems (not all are show stoppers, but they give you hints that something is not according to the standard for jsf, jsff, jsp or jspx pages.
Have you checked that the bean is correctly defined and that it's reachable?
Start a fresh page and isolate the problem, e.g. build a selectOneChoiuce on the new page (don't copy it as you might copy the error too) and make it work on the new page. Once you have it running you can compare the solution to your not running page.

How do I declare a native method outside of the main class?

Hi
This is a JNI particular question.
I am having a problem with generating the header .h file after executing javah. The file is generated correctly but is empty under certain circumstances.
This is the 'empty file:
=================
/* DO NOT EDIT THIS FILE - it is machine generated */
#include <jni.h>
/* Header for class gui_GuiMain */
#ifndef Includedgui_GuiMain
#define Includedgui_GuiMain
#ifdef __cplusplus
extern "C" {
#endif
#ifdef __cplusplus
#endif
#endif
This is what it should look like:
=========================
/* DO NOT EDIT THIS FILE - it is machine generated */
#include <jni.h>
/* Header for class gui_GuiMain */
#ifndef Includedgui_GuiMain
#define Includedgui_GuiMain
#ifdef __cplusplus
extern "C" {
#endif
* Class: gui_GuiMain
* Method: getValueOIDTestMIB
* Signature: ()V
JNIEXPORT void JNICALL Java_gui_GuiMain_getValueOIDTestMIB
(JNIEnv *, jobject);
#ifdef __cplusplus
#endif
#endif
The header file becomes "empty" when the native function getValueOIDTestMIB is declared in a different class than what my main() function is declared in.
For example something like this will work:
class Main
public native void getValueOIDTestMIB
static {
System.loadLibrary("libsnmp++");
//............some more functions etc.............
public static void main(String[] args)
//............some more stuff...........................
But when I declare this:
public native void getValueOIDTestMIB
static {
System.loadLibrary("libsnmp++");
outside the class, in another class within the same package, nothing happens.
I am probabily doing something stupid. Can somebody help or give me some guidance to where I should look. I come from a C++ background, not a guru in Java.
Thanks

You need to run javah and give it as a parameter the full class name of the class which contains the native methods.
For example (if your class is called A and its package is a.b.c)
javah -jni a.b.c.A

Can we call a static method without mentioning the class name

public class Stuff {
     public static final int MY_CONSTANT = 5;
     public static int doStuff(int x){ return (x++)*x;}
import xcom.Stuff.*;
import java.lang.System.out;
class User {
   public static void main(String[] args){
   new User().go();
   void go(){out.println(doStuff(MY_CONSTANT));}
}Will the above code compile?
can be call a static method without mentioning the class name?

Yes, why do it simply?

How to find the class name, the location from where it invoked a method

Hi,
I have a class A. The caller calls A.someMethod(), whenever this method is invoked, I want to find out the caller info, which class invoked this method, from where this class was loaded (may be the jar file name). Any help will be appreciated.
Thanks.

However since version 1.4 there is an easier way to extract that information from the Throwable:
java.lang.Throwable
public StackTraceElement[] getStackTrace()
Provides programmatic access to the stack trace information printed by printStackTrace(). Returns an array of stack trace elements, each representing one stack frame.

How to call a method of a class where the name of method is string

i have a method of a class in the form of a string and i have the object of the class to which it belongs .what i want to do is call this method.
for ex:
S1 s=new S1();
// this is the object of my class. this class has one method called executeMe()
String methodname="executeMe";
//i have the name of the method with me in the form of string.
so how can i call the class's method in this scenario from the string like what should i write in sucha way that i get s.executeMe(); it is not presumed that this will only be the method that will be called. there maybe some other method too and it has also to be called this way. so please guide.

S1 s = new S1();
String name = "executeMe";
Method m = s.getClass().getDeclaredMethod(name,null); // no parameters
m.invoke(s,null);Built from memory, maycontain flaws.

Method/Class of the day.
