Structure of a return method

Hello Again
I am having trouble understanding the structure of a method which returns a value, i know that a void method looks like
public static void methodName (parameters){
//code
}but if u wish for the function to return a value (removing the void) what must u do? i keep having attempts at doing ti myself but keep having trouble.
Thanks
Dom

To be honest, I'm surprised that you're handling JScrollPanes, but do not know how to write a method that returns anything...

Pass the structure name and return the description fields.

Hi experts!!,
I would like to know a class and the method that I pass the structure name and return all the description fields.
Thanks a lot

Hello Ana
Have a look at class CL_ABAP_STRUCTDESCR.

lo_typedescr = cl_abap_structdescr=>describe_by_data( ls_knb1 ).
lo_structdescr ?= lo_typedescr.
lt_dfies = lo_structdescr->get_ddic_field_list( ).
" Or check public attribute: lo_structdescr->components   for non-DDIC structures

Void Methods and Value Returning Methods in Java

Hello,
I'm new here so please let me know if I overstep any of the rules or expectations. I merely want to learn more about Java Programming efficiently, and easily. I can ask and discuss these topics with my online prof, but she doesn't have much time.
So right now I'm trying to solve a problem. It's a typical college level computing problem which I've already turned in. So I'm not looking for someone to do my homework for me or something. It's just that the program didn't work. Even though I probably won't get a very good grade for it, I want to
make it work! I'm kind of slow when it comes to java so just bear with me.
The prof wanted us to write an algorithm that reads a student's name and 6 exam scores. Then it computes the average score for each student, assigns a letter grade, using a rating scale:
90 and above = A
80 - 89 = B
70 ? 79 = C
60 - 69 = D
Less then 60 ? F
We had to use a void method to determine the average score for each student, a loop inside the method to read the and sum the 6 scores but without outputting the average score. The sum and average had to be returned in and output in void main.
Then we had to use a value-returning method CalculateGrade to determine and return the grade for each student. But it can't output the grade because that must be done in void main.
Finally the class average must be output.
Our prof gave us a list of student names with their 6 scores.

So all the data had to be read from a file and the results output to a file. Also we couldn't use 'global variables'. We had to use the appropriate parameters to pass values to and from methods.
Question 1: What does she mean by 'no global variables'? Maybe she means: don't use "*double test1, test2, test3, test4, test5*;"
Anyway because I'm a slow learner with Java, I end up looking for sample programs that seem to do a similar job as the problem posed. So with this program I decided to adapt a program called Comparison of Class Averages.

I guess I was trying to find a shortcut that ended up being a long cut. Here's the algorithm I wrote.
Algorithm
1.) Initialize the variables
2.) Get the student name and his/her accompanying 6 exam scores, limiting the number of scores to 6.
3a.) Calculate score of 6 exams for each student using void method called CalculateAverage.
3b.) Use a loop inside the method to read and sum the six scores.
4.) Use value-returning method CalculateGrade to determine and return each student's grade.
5.) Output each student's grade in void main.
6.) Calculate the average score for all students
7.) Output entire class average
And now I'm trying to piece together code to match each step of the algorithm starting from scratch.
So I got the code for outputting each students grade in void:
public static void printGrade(double testScore)
System.out.print("Line 10: Your grade for "
+ "the course is ");
if (testScore >= 90)
System.out.println("A");
else if (testScore >= 80)
System.out.println("B");
else if (testScore >= 70)
System.out.println("C");
else if (testScore >= 60)
System.out.println("D");
else
System.out.println("F");
This code can read the the file with the scores:
Scanner inFile =
new Scanner(new FileReader("a:\\studentlist.txt"));
PrintWriter outFile =
new PrintWriter("a:\\avg.out");
courseGrade = inFile.nextDouble();
studentName=inFile.nextChar();
while (inFile.hasNext())
studentName= inFile.next().charAt(0);
courseGrade= inFile.nextDouble();
I'm just trying to piece this thing together. Any tips would be appreciated. I will return with more pieces to the puzzle soon. As you can tell it's all kind of disorganized, and scatterbrained. Just trying to find some simplification or distillation, or recommendations.

Hello,
Thanks for your reply. So I take it you are more familiar with Object Oriented Programming more than Procedural Based Programming?
Well the teacher insisted I follow the algorithm instead of trying to adapt another program to the problem. But sometimes that approach saves time I've noticed since many of the code examples we study in Java are like 'the golden oldies'.
The student gradebook problem is repeated over and over in different forms. Maybe if I just approached the problem more linearly:
Algorithm
1.) Initialize the variables
String studentId
int numberOfStudents
DoubleClass avg = new DoubleClass(); //average for a student
double avgGroup: //average for all students2.) Get the student name and his/her accompanying 6 exam scores.
Scanner group = new Scanner(new FileReader("c:\\list.txt"));
PrintWriter outfile = new PrintWriter("c:\\student.out"));
3a.) Calculate score of 6 exams for each student using void method called CalculateAverage using a loop to read and sum the six scores. The loop must be inside the method. It does not output the average score. The sum and average must be returned and output in void main.
method calculateAverage
double totalScore //to store the sum of all the scores of each student
int numberOfExams; //to store the number of
int score; //to read and store a course score
double totalScore = 0.0
int numberOfExams = 0;
int score = 0;3b.) Use a loop inside the method to read and sum the six scores.
Using psuedocode (since the variables have been declared and initialized)
i)get the next student score
RIght here my approach of adapting another program to my new program becomes problematic
the pseudocode here is:
ii) while (score != -999):
I.) update totalScore by adding course score read in step i.
II.) increment numberOfExams by 1
III.) Get the nex student score
iii) studentAvg.setNum(totalScore / numberOfExams);
*What is the purpose of the statement while (score != -999)?*
I don't see why they picked -999? Will this loop allow me to read an endless number of student names and theri accompanying number of exams and then find the average for each student?
I'll go into the next algorithmic steps later.
4.) Use value-returning method CalculateGrade to determine and return each student's grade.
5.) Output each student's grade in void main.
6.) Calculate the average score for all students
7.) Output entire class average
Thanks ahead of time for any suggestions, tips.

Dual WAE's in mixed return methods?

Today we have a single 7341 attached directly to the router's Gi0/1. The original WAE uses Forwarded return. Lastweek we received a second 7341 (and 15 other WAE boxes for branch sites). Since we can not connect a second WAE directly to the router without adding a switch between them, we planned on eventually moving both 7341's to our internal LAN segment. Our new 7341 will be provisioned on the internal LAN and will use GRE Negotiated Return to the routers Loopback interface. Once the new 7341 is up and running we plan on moving our original 7341 to that same architecture.
Does this present an issue? Will the router have an issue with service group 61 and 62 having two WCCP clients, using different return mechanisms?
7341#1 = Forwarded Return (Directly connected to router, L2)
7341#2 = GRE Negotiated Return (On Internal LAN, Routed)

Just to clarify, both of these 7341 boxes will be in the same WCCP service groups. (61 LAN & 62 WAN). The "Return method" is GRE for both.
"However please note that the packet return method should be the same."
7341#1
wccp router-list 8 10.X.X.1 (Gi0/1 on router)
wccp tcp-promiscuous service-pair 61 62 failure-detection 30
wccp tcp-promiscuous service-pair 61 62 router-list-num 8
wccp version 2
7341#2
wccp router-list 1 10.X.X.129 (Loopback1 on same router)

Using return method to do this assignment

Write a method to delete character in a string.
Example:
A call to deleteChar(?hello?, ?l?) will return heo
A call to deleteChar(?madam?, ?a?) will return mdm
I have tried to solve this problem using return method, but it doesn't work. Please help me do this exercise with return method in main method.
Here is my work, using void method in main method
     private static void deleteChar(String input, String deletedChar) {
          for (int i = 0; i < input.length(); i++) {
               if (!(input.charAt(i) + "").equalsIgnoreCase(deletedChar)) {
                    System.out.print(input.charAt(i));
     public static void main(String[] args) {
          String input, deletedChar;
          Scanner kb = new Scanner(System.in);
          System.out.print("Enter a String: ");
          input = kb.nextLine();
          System.out.println("Enter a letter you want to delete from String: ");
          deletedChar = kb.nextLine();
          deleteChar(input, deletedChar);
     }

In your main method, you replace the line
deleteChar(input, deletedChar);by
String result = deleteChar(input, deletedChar); and the method by :
private static String deleteChar(String input, String deletedChar) {
    return input.replaceAll(deletedChar, "");
}

What do you mean by "return method"? Methods return a value (or void, but that's still a "value" of sorts).

WCCP src group & redirect/return method

Has anyone here implemented 3rd party WAN optimization such as Bluecoat or Riverbed w/ WCCP?
What service groups and redirect/return methods did you use, and on which Cisco switch/router platforms?
I'd like to know what works, and what doesn't...
It looks like you generally use service group 61 & 62 to redirect all TCP traffic to WAAS, based on source/destination IP's.
Do those two service groups also work w/ 3rd party devices?
If they don't, do I just pick some random service groups, other than the well known ones?
How would the switch/router know what traffic to redirect, if no redirect-list is used?
The Networkers' wccp presentation slides say if GRE is to be used w/ 6500's, generic GRE needs to be used instead of WCCP GRE.
Where would you configure what type of GRE is used, within WAAS?
Does anyone know if such setting exists on 3rd party devices?
Our Bluecoat SE isn't even aware of two different versions of GRE, and neither was I, before I watched the Networkers session.

Hi,
I know with Riverbed you can use wccp 61/62 as well. I don't have experience with other vendors though.
The router knows what to redirect based on the WCCP service number. It can be a well-known service or a custom service where you define what to redirect directly on the optimizer/web-cache device. The redirect list is only used to further limit what is redirected.
In h/w forwarding platform WCCP GRE is handled in s/w, this is why using generic GRE is suggested. On WAAS you can configure it using "egress-method generic-gre intercept-method wccp"
For more details check the "Egress Method" section in the following doc:
http://www.cisco.com/en/US/prod/collateral/switches/ps5718/ps708/white_paper_c11-629052.html
Here you have WCCP redirection method supported and suggested for different Cisco platforms:

Maintain Structure Relations - LSMW - IDOC method

Hi,
Trying to use LSMW Idoc method to upload BP masters.
Have maintained the ports, partner types, message types etc. When I reach the "Maintain structure relationship" step, I have a very big tree structure under EDI_DC40 when am trying to maintain the structure relationship between the source and the target in LSMW idoc method.
Do I need to maintain my relationship at all the levels of the tree structure under EDI_DC40 or can I choose the nodes that are relevant and maintain a relationship only for them?
Is there a short cut or a way where I can maintain relationship for each node under the target strucute EDI_DC40.
Appreciate your inputs.
SK

Hi SK,
There is no need to maintain EDI_DC40.
In 'Maintain Structure Relations' step, you just need to create Relationship for the structure you want the information be uploaded in the BP. Mapping of the fields in the structure to your upload file's values will be done in next step. Hope the above helps

Compiling errors and return methods

Returning the result of method in return statement.

hi,
If I write the following line of code then will there be any problem or what issues will arise
return method(x,y);Is it a good programming practice, if not why?

It's perfectly valid syntax. This is a stylistic concern. Opinions on style vary far and wide according to each programmer's bias, personality, past experience, and what they had for lunch that day.
Personally, I would be fine with return foo(); if:
- It were the only line in the methodO_o
Why would that matter?
- The name of foo made it reasonably clear what it was doingSounds good, but shouldn't all method have good names?
>
I would avoid it if:
- It was likely that the method calling foo would be frequently changed to expand its functionalityWhy does it matter?
- foo returned a type of variable that should be named as a local variable simply to improve readabilityDoesn't matter what I eat to lunch, I would never agree on that :)

HU_CREATE_GOODS_MOVEMENT returned error structure question

Hello,

Wsdlc with jaxws - missing method on bean

One, at least, of the POJOs created by "wsdlc" for JAX-WS is missing a "setter" method. The "getter" exists. The corresponding "setter" is missing.
I generated a Web Service from a WSDL file using "wsdlc". I generated the JAX-RPC and JAX-WS Web Service. I compared one of the POJOs. The JAX-RPC version has the correct "getter" and corresponding "setter" methods. The JAX-WS version is missing a "setter". The code below is missing: setResponseStatusMessage.
Is there a bug in "wsdlc" related to generics?

Export field symbol table out of method

Hi,
i have a report, that takes any xml and converts it into a table structure. In a method I generate the table structure using method cl_alv_table_create=>create_dynamic_table. Later in the same method I have filled the content of the XML file into a table typed as: FIELD-SYMBOLS: <outtab> type standard table
Now I need to export this <outtab> out of my method. Because it is a unspecific field symbol table, I can not do this, by normal exporting.
In the PAI, where my method is called, I have deffined the table to return into as:
FIELD-SYMBOLS: <itab_message> type standard table.
Any help will be greatly appreciated.
Kind regards
Mikkel

getDeclaredMethods() - I believe this might do what you want. It throws a SecurityException, but I'm not sure exactly under what circumstances! Oh, and it doesn't return methods defined on any superclasses.
