Use methods in other classes

Can I use methods from other classes than the class that myClass extends?
ex. myClass extends parentClass{
myMethod()
myMethod() is declared in i third class. Is this possible or can I only use classes from the parent class?
-Thanks-

I'm not really sure what the previous two answers were getting at.
Yes, you can use methods all the way up the class hierarchy, as long as they are visible.
For example, Object implements toString(). You can call toString() on any object in Java and it will render the object to a string in one way or another. That is because toString() is public.
If toString() were protected, you would only be able to call the method if you were a subclass of of that object (or in the same package), which would make the toString() method much less useful.
I would suggest reading up on the differences in the four visibility modifiers (private, (default), protected, and public). Private is the only one which nothing else can call. If you are public or protected, any subclass can call the method, even if there are 20 superclasses between the implementor and the caller.
Good luck!

Use methods of another class

Dear Sir/madam,
i have a question about using methods of another class. I will explane:
i have made a class which is called A. This class has some attributes (studentName and examRank) and some methods.
Now i need to made another class called B. Now i want to make an array where i can add some attributes of objects which i made of class A. How can i do that?
Kind regards

Here's a for-instance that doesn't use your exact program but demonstrates the point:
public class A
int value;
String name;
public A(int value, String name)
 this.name = name;
 this.value = value;
public int getValue()
 return value;
public String getName()
 return name;
public String toString()
 return name + ": " + value;
import java.util.Arrays;
import java.util.Random;
public class B
private static final String[] NAMES =
 "Sunday", "Monday", "Tuesday", "Wednesday", "Thursday", "Friday", "Saturday"
private static final int MAX = 100;
private A[] myAs = new A[NAMES.length];
private Random random = new Random();
public B()
 for (int i = 0; i < myAs.length; i++)
 myAs[i] = new A(random.nextInt(MAX), NAMES);
public String toString()
return Arrays.toString(myAs);
public int getTotal()
int temp = 0;
for (int i = 0; i < myAs.length; i++)
temp += myAs[i].getValue();
return temp;
public static void main(String[] args)
B b = new B();
System.out.println(b);
System.out.println("Total: " + b.getTotal());

How to pass entire class as a parameter in a method of other class- OpenScr

Whenever we create a script in OpenScript, it can contain only one class. However I want to declare several variables in a class/script and pass this entire class B as a parameter in a methodA of classA.
What I mean by mean that is , I create ClassB something like below
public class MyParams.....
variable1;
variable2;
variable3;
variable4;
variable5;
public class Original.....
public void methodA(MyParams params)

Hi
I have a stand alone program (can be used by all other users) which will accept request_id and To_Email as parameters. I am developing a new request set in which I want to incldue this stand alone program and want to pass Prog#1 request Id to the 2nd stand alone program as a parameter so that I can send the output of the Prog#1 to the users through E-mail.
Do we have any options to pass Prog#1 requeset id in to Prog#2 as a parameter in the request set without modifying the stand alone concurrent program code.
Please note that i dont want to change stand alone program code becuase this code/program was developed to work in general for all the users and I dont want to change this code for new requirement/purpose...
Hope you understood my requirement...
Thanks!!

Transaction code which using method of a class as start object

Hi all,
I'm creating a new tcode 'Z123' which is tied to a method of a class in SE93. However, when I run this tcode and into debug mode, SY-TCODE will always return OS_APPLICATION. How can I get the actual tcode, which is 'Z123' into my program?
Thanks in advance

You can try using the method GET_CURRENT_TRANSACTION of class CL_DYNPRO. Check this SAP documentation for details:
... the method GET_CURRENT_TRANSACTION of the class CL_DYNPRO can be used to obtain the transaction code of the current transaction. This method returns the transaction code during a parameter transaction or variant transaction instead of the transaction code of the implicitly called dialog transaction.
But if i try checking sy-tcode in a tcode bound to a method of a class i get the correct tcode & not OS_APPLICATION.

Use method from father class for event

Hi,
I want to use a preDelete event in my class, but the method I would like to call for the event is not in the class itself, but in the (abstract) predecessor class. Any chance to do this? At the moment I can't select the method in the event tab page (it's not in the list to choose from ...)
Thank you!
J.F.

In 9.0.4 you will need to add the parent class as a descriptor and choose to deactivate it. This will allow you to choose methods from that class in the subclass descriptors.
In 10.1.3 there is a dialog for specifying classes that are not persistent, but necessary in other persistent classes: http://www.oracle.com/technology/products/ias/toplink/doc/1013/main/_html/mw007.htm#sthref629
A good explanation of why we don't store the parent and referenced classes unless explictly asked can be found here: Re: Mapping Workbench 10.1.3.0 Bug - Cannot add Implemented Interfaces
Hope this helps,

How to use method of Standard Class

Hi all,
I want to call a pop up in pcui screen in some standard application with some text. I have made Zclass of standard SAP class which i am using (cl_bsp_accmod_contact in CRM system).
I think i have to call 'PRINT_STRING' method of standard class CL_BSP_ELEMENT.
I am trying to use this code: 

data: lr_data type ref to cl_bsp_element.
concatenate html 'rohit' into html. (html is a string)
lr_data->print_string( html ).
but it gives a dump:
You attempted to use a 'NULL' object reference (points to 'noth
access a component (variable: "lr_data").
An object reference must point to an object (an instance of a class)
before it can be used to access components.
I dont know how to assign object reference to an object???
Plz help me in this regard,
Thanks in advance,
Rohit

Hi ,
try and use :
data: lr_data type ref to cl_bsp_element.
concatenate html 'rohit' into html. (html is a string)
lr_data->print_string( html = html ).
You are creating a variable...but not passing the value to the parameter...it is exactly like callin get_data or get_cell_value...!!
Hope this helps.
Do reward each useful answer.
Thanks,

Calling methods from other classes

I have a bunch of little java files in a folder, do I need to make a package in order to access all the methods in all the classes, or can I just make an instance of any of the methods because all the classes are in the same folder?

HI,
If your methods have a "public" modifier (and the class does too) then you can instantiate your classes as objects from that (so-called) "default" package in any other class or object in any other package and then call the methods on those instantiated objects as you please.
If that sounds confusing... I'd seriously try the excellent tutorials at this site, especially "the java tutorial".

On the left, you have wired 2 sources on the same tunnel/wire, so that's 1 broken wire.
In the For loop, you are trying to wire a "Red" object from the first subVI to the input of the "Green" subVI, so a "Green" object. If Red is not a descendant class of Green (or share a common ancestor), it is not permitted.
FInally, the output of the For loop, is a 1D array of "Green" objects, which is probably not the same data type as the input of the last subVI on the right (it's probably a "Green" object scalar).
Overall, you can use the "List Errors" dialog box (Ctrl+L) to debug your code, and make exhaustive use of the contextual help (Ctrl+H) to see what is going on when focusing a broken wire.

Help required: Using objects/methods in other classes

Hi
Say you have a class that has a private string instance variable and you have a accessor and mutator method for this object in that class.
You have another class that needs to access this object via the accessor and mutator methods. How do you do this? When I try I only get nullPointerExceptions or Stack Overflows!!! If anyone can provide some code on how to do this successfully then that will be most appreciated. Thanks.

Kayaman gave you the right answer
public class MyDataClass {
private String importantString;
public void setImpString(String s) {
importantString = s;
public String getImpString() {
return importantString;
public class MyMainClass {
public static void main(String[] args) {
MyDataClass a = new MyDataClass();
a.setImpString("This is important");
System.out.println(a.getImpString());
}Note that he sets the value of the imp string before trying to get it. The nullpointer that you say is probably because you dont do that.
Also When you aks a question a little humility doesnt hurt.
You do need a tutorial first.

Explizit using methods of base class

when using a base class reference from an abstract class A and creating an object of subclass B
A ref_A = new B();
assuming we have implemented the method m() in A and B, then
ref_a.m()
calls Method m of subclass B
(dynamic binding, fine)
Is there a possibility to force explicitely the call of method m of superclass A.
(i mean not a call from Method m in B with super())

are you absolutely sure ?I am sure. Perhaps you are thinking of C++ (and if you're not, I am!) where you can write: ref_A.A::m(),
but there's no way from the client code to do that in Java. If you really need to do this, your
design of A should reflect it:
public abstract class A {
    public final void mOldSchool() {...}
    public void m() { mOldSchool(); }
public class B extends A {
    public void m() {...}
}I agree with Kayaman, though: question your design. In the abstract, this is a shakey design.

Acessing Methods From Other Class....

Hi,
Im creating a Estate Agent system for a project.
Basically I have 4 class..
Customer.class
AddCustomer.class
Buyer.class
Seller.class
The Customer class is used to create an instance of a customer in order to do things with this information latter on by passing values to it from the AddCustomer.class where the user inputs this information . The AddCustomer adds information to the database that the user has inputted.
What i want to do with the Buyer and Seller class though is access this customer information that has been passed from AddCustomer to the Customer class... Im Just To Sure How...

Nope....
