Difference between compare nad compareTo method

difference between compare nad compareTo method

compareTo is a method of the Comparable interface; it takes one argument and compares the current object to that argument; it provides a default ordering of the objects of this class
compare is a method of the Comparator interface; it takes two arguments and compares them; it is used to provide an external ordering, either for things that don't already have an ordering, or to provide a different ordering than the one they already have

What's the difference between equals() and compareTo() method

I'm confused between the two method from String class ,,, what's the main difference between equals() and compareTo() method?

API docs give quite clear information IMHO
public boolean equals(Object anObject)
Compares this string to the specified object. The result is true if and only if the argument is not null and is
a String object that represents the same sequence of characters as this object.
public int compareTo(String anotherString)
Compares two strings lexicographically. ....
The result is a negative integer if this String object lexicographically precedes the argument string. The
result is a positive integer if this String object lexicographically follows the argument string. The result is
zero if the strings are equal; compareTo returns 0 exactly when the equals(Object) method would return
true. Mike

Difference between Function Module Vs Method in Class Module

1) Can you please tell the difference between the Function module used in abap program and the method of the class module used in abap programming.
2) does it necessary to do commit statement after calling the function module.
Thankyou for you time.
Bhaskar.

Hi,
1)
Check this difference..
The main difference between real object orientation and function groups is that although a program can work with the instances of several function groups at the same time, it cannot work with several instances of a single function group. Suppose a program wanted to use several independent counters, or process several orders at the same time. In this case, you would have to adapt the function group to include instance administration, for example, by using numbers to differentiate between the instances.
2) COMMIT WORK is required for BAPI..And not required when you normally call a function module..Unless required ..
Example
Update function modules requires COMMIT WORK to execute the function module.
Thanks,
Naren

i understand here if EMAIL_L is like @yahoo.com then it returns @thoyahoo.com
select count(REPLACE(EMAIL_L,'%@yahoo.com%','%@thoyahoo.com%')) FROM SIEBEL.MAIL
and here also if EMAIL_L has @yahoo.com then it returns @thoyahoo.com

Difference between Error Status in Method Exception

Hi all!
There are three checkboxes under 'Exceptions' for each method in a Business Object. They are Temporary Error, Application Error and System Error. Could anyone please tell me when are we supposed what type and why?
Also, is this true that if we use Temporary Error then the particular Step in the workflow (that calls the method with exception) will remain "in process"? In that case, should be use Application Error/System Error?
Thanks in advance!
MA

Hmmmm. So you don't want to do anything and let us do the work? But ok I'll help you out. Search this forum and look in the results for a question by Hari about the same problem.
I could find it pretty quick, so I guess so should you.

Interested in Performance Difference Between Different SL Install Methods?

Go here: http://discussions.apple.com/thread.jspa?messageID=10077299&#10077299.

Run a benchmark for your specific case??
Yes. If you are to implement such an operation, try both, using your actual data, and see which performs best. I can't speak to this particular case, but very often to performance questions is
it depends. So the only way to find out when you are interested for a specific case is to test. And keep in mind that next time it could be different.

Difference between All valuation methods

Hiii Guru's,
Can anybody tell me the actual difference between the inventory valuation methods given in B1 - Standard / Moving / FIFO ... Actually I want to know their impact in each case if I maintain my masters at item group level. so how it will affect my accounts... preferrably give examples in each case to understand the different scenario...
Thanks in advance. I will assign points for helpful asnwers.
Regards,
Abhishek

Hi,
Standard :-
This valuation method means the cost of an item will be standard. It never change under any circumstanses. The Only way to change the cost is to Inventory Revaluation.
Eg, Lets consider Item A
Valuation Method : Standard
Value : $56.00
The above value will be taken to any calculation.
Moving Average :-
This means a valuation takes place based on the corresponding quantities and prices for each goods receipt and issue, and the moving average price is updated accordingly. The valuation price is calculated as the quantity multiplied by the average price.
Eg, Let's Consider Item A
Valuation Method : Moving Average
Value : $56.00
If we purchase the item for $60.00 then the item cost will be changed according to the purchase value. In this Moving Average Value will be th item cost.
FIFO :-
Under this valuation method, the system assumes that the items that entered the warehouse first will also exit first. This means goods issues are valuated with the prices that are valid for the first goods receipts.
Eg., Let's consider Item A,
Valuation Method : FIFO
Value : $56.00
The current value of the item is $56.00. If we purchase the item for $60.00 then the item will have two values, ie., items which bought first with $56 and currently bought with $60.00. The item issue will be done in FIFO manner. (ie., items with $56.00 value will be issued first and then stock with $60.00 will be taken)

Main difference between these 2 methods

HI
what is the main difference between updateOrder and repriceOrder methods in any form handler
please give me exact difference

Both are totally different operations. repriceOrder method invokes the pricing engines and calculators to calculate the order prices whereas, updateOrder method saves the changed order properties to the database.

Difference between Reboot and Power OFF/ON

Hi Community,
in a forum a User is reporting serious problems after an update to the actual major release 10.6.5. He said if he boot the system in safe mode everything works as expected, after a reboot the same but after a power off and on again, the system is freezing after the login.
Now I'm searching for the difference between this two start methods, maybe we can isolate the problem a bit easier.
Thx & Bye Tom

If the operating system is running when the power button is used to stop the computer, this can do great harm to the disk by not allowing all of the data to be written to disk as it should be.
Yes I agree but this wasn't what I'm asking for. The question is why the system works fine as long as the User proceed a normal reboot and why it is broke after a shutdown. I don't believe that the User enforce a dirty shutdown after he boot the system in safe mode. But sure, if he boot the system after a shutdown, and the system is freezing, than he have to proceed a dirty shutdown. What else could he do?
Thx & Bye Tom

Difference between methodName(a,b) and a.methodName(b)

I've written the 2 following methods:
public boolean equals (Object o)
if (this==o) return true;
if (!(o instanceof Point)) return false;
Point p= (Point) o;
return (this.getX()== p.getX()) && (this.getY()== p.getY());
public static boolean equals (Object o1, Object o2)
if (o1==o2) return true;
if ((!(o1 instanceof Point)) || (!(o2 instanceof Point))) return false;
Point p1= (Point) o1;
Point p2= (Point) o2;
return (p1.getX()== p2.getX()) && (p1.getY()== p2.getY());
Both seem to work the same. Why do i have to declare the second one as static?
Which is the difference between them? "clone" method is just an example. This question applies in general for methodName(a,b) and a.methodName(b).
Thanks

For static, see
http://www.martinrinehart.com, Articles, What Is Static?
jverd is right, the first is more OO. But in SmallTalk you pass the message "+2" to a "2" object if you want to get 4. Very OO and just plain dumb.
Before the word "pattern" was applied to these things, every programmer built a personal library of useful routines to call as needed. If you work with Points, that static routine should be part of your library.
By the way, the O1==O2 check isn't needed. It will save a microsecond if it's true, but you should code like a backpacker packs: when in doubt, leave it out.
