So I'm coding a gene algorithm and ideally I start off by placing some float variables in a hashmap. These will be the genes that are passed on to different objects.
ie
genes.put("mass", 200);
genes.put("lifespan",0);
genes.put("intelligence",0);
genes.put("dexterity",0);
genes.put("endurance",0);
then later I want hashmap values to be updated when there is a change in the variable. This is the code I have so far;
if(updategenes){
for ( String key : genes.keySet() ) {
System.out.println( key );
try{
String a = key;
Field field = a.getClass().getField(key);
genes.put(key,field);
}catch (NoSuchFieldException e) {
}catch (IllegalAccessException e) {
}}
updategenes = false;
}
only issue is it wont accept field as an int even though thats the only possible type that could ever be in field at the time. Any suggestions?
int strValue = (int) field.get (key);
How to get string value from a Java field via reflection?

I have a piece of code working as expected in Android but not in iOS. Problem is the value of the final variable 'nombre' which in Android gets the expected value, whereas in iOS it gets a different one randomly chosen from the list (specified in codesnippet provided)
public AsignarNombreCDF(){
this.departamentoId = AdministradoresApp.departamentoId;
this.setLayout(BoxLayout.y());
this.setTitle("Asignar Nombre a CDF");
TopBarUtils.addMenuToTopbar(this);
TopBarUtils.addCommandToTopbarMenu(this, "Inicio Departamento", e->{new MenuDepartamento(departamentoId).show();});
try {
Map m = Utils.consultaWebService("newfoldernames", new Object[]{"department", departamentoId});
String folderNameMatrix = (String) m.get("FolderNameMatrix");
Map m_ = (Map) JSONUtils.fromJsonString(folderNameMatrix);
Iterator it = m_.keySet().iterator();
while(it.hasNext()){
String k = (String) it.next();
final String nombre = (String) m_.get(k);
Button b = new Button(nombre);
b.addActionListener(e->{cargarFotos(nombre);});
this.add(b);
}
int y = 2;
} catch (Exception ex) {
Utils.gestionaExceptionUi(ex);
}
}
Problem is that the final variable nombre seems not to assign correctly to the value passed to the button listener. This as already said, only happens in IOS and not in Android, where we never get a mismatch. Any chance that the iOS build system might oversee this situation?. Any ideas how to overcome the problem?

I have following Code where i will receive list of names as parameter.In the loop, first i'm assigning index 0 value from list to local variable name. There after comparing next values from list with name. If we receive any non-equal value from list, i'm assigning value of result as 1 and failing the test case.
Below is the Array list
List<String> names= new ArrayList<String>();
names.add("John");
names.add("Mark");
Below is my selenium test method
public void test(List<String> names)
String name=null;
int a=0;
for(String value:names){
if(name==null){
System.out.println("Value is null");
name=value;
}
else if(name.equals(value)){
System.out.println("Received Same name");
name=value;
}
else{
a=1;
Assert.fail("Received different name in between");
}
}
How can i convert above code into lambda expressions?. I'm using cucumber data model, hence i receive data as list from feature file. Since i can't give clear explanation, just posted the example logic i need to convert to lambda expression.
Here's the solution: it cycles all element in your list checking if are all the same.
You can try adding or editing the list so you can have different outputs. I've written the logic, you can easly put it into a JUnit test
List<String> names= new ArrayList<>();
names.add("John");
names.add("Mark");
String firstEntry = names.get(0);
boolean allMatch = names.stream().allMatch(name -> firstEntry.equals(name));
System.out.println("All names are the same: "+allMatch);
Are you looking for duplicates, whenever you have distinct value , set a=1 and say assert to fail. You can achieve this by :
List<String> names= new ArrayList<String>();
names.add("John");
names.add("Mark");
if (names.stream().distinct().limit(2).count() > 1) {
a= 1,
Assert.fail("Received different name in between");
} else {
System.out.println("Received Same name");
}
Hitting this issue with changing certain enumeration-based fields in my new RTC work item for a RTC API tool I'm working on.
Basically, I get an ImmutablePropertyException the first time I change the field, but the next time it works without an exception.
Want to get rid of the exceptions. I'm using a value RTC is actually returning to me as a valid enum value for the field.
Assigning RTC work item field: odc.impact a field value of ->
Integrity [odc.impact.literal.l4]
EXCEPTION: Could not assign value,
even though it was found in the enumeration list: [Unassigned,
Installability, Standards, Integrity]

RTCMain.out(msg2);
w.setValue(a, literal.getIdentifier2()); // (REO) SOURCE OF PERIODIC EXCEPTION
return true;
}
}
} catch (Exception e) {
RTCMain.out("EXCEPTION: Could not assign value, even though it was found in the enumeration list:\n\t[" + b + "]");
e.printStackTrace();
RTCMain.out("");
return false;
}
RTCMain.out("VALUE NOT FOUND: Valid values are:" + b);
return false;
}
Anyone know why I'm getting the periodic ImmutablePropertyException for only some of the fields, and why it goes away on the second call?
Thanks!
You just need to use the workingCopy.getWorkItem() object passed in to the execute() call rather than a cached version in a member variable. The attributes on the workingCopy object are not immutable and work fine.
public class WorkItemCreator extends WorkItemOperation {
...
#Override
protected void execute(WorkItemWorkingCopy workingCopy, IProgressMonitor monitor) throws TeamRepositoryException {
IWorkItem newWorkItem = workingCopy.getWorkItem();
// Set attribute values on newWorkItem to avoid ImmutablePropertyExceptions
I am trying to "insert" (or) "add a row" to Purchase Requisition using standard BAPI (PurchaseRequisition.CreateFromData).
I am using JCo3. The example in JCo3 indicates that we should use table.appendRow() OR table.insertRow() methods. I am trying with table.appendRow() & table.appendRows(1). When i try to insert a row, i dont get any error and the row is not inserted.

I did not understand how to read the response and am trying to fetch it from exportParameters!!
Can anybody share a piece of code to insert and
getting confirmation response (do we get the PREQ_NO in response?)
I am adding date field value as "20131101", but not sure if the format and approach is right?
when i try to add Quantity column value, i get an error message complaining this column is not part of BAPIEBANC. But the column is visible in BAPIEBANC type.
any configuration on SAP side to be checked?
should i activate any fields in JCo side? if so, how
Please note that my knowledge on SAP is very limited.
Waiting for an expert's response.
Thanks.
First, you should take a look at SAP JCo documentation, e.g.
http://help.sap.com/saphelp_nw04/helpdata/en/6f/1bd5c6a85b11d6b28500508b5d5211/content.htm
Regarding your code:
Adding (one) row to the table looks right on first sight.
Your code says QUANITY instead of QUANTITY.
You should add date values as java.util.Date; if creating a Date from a String format, you should use java.text.DateFormat.parse(). See http://docs.oracle.com/javase/6/docs/api/java/util/Date.html (this is however Java specific and has nothing to do with JCo).
If changing anything in SAP, never forget to call BAPI_TRANSACTION_COMMIT in the end to finish the logical unit of work (aka transaction) or nothing will actually be changed.
If you don't like to fiddle with the more or less complicated and verbose JCo API, try using Hibersap which gives you a much nicer programming model when calling functions in SAP ERP: http://hibersap.org.
However, you will still need a basic understanding on how SAP function modules work technically (such as parameter types or data types) as well as on the domain specific model which lies behind them (in your case, creating a requisition). I.e. you may need to communicate with your SAP experts.
Here I added 2 types of insertion :
insertval() function for user defined module resides in sap with the help of abap programmer
Its an standard module for insert a ticket using jco to SOLMAN system. First you have to analyse import, export, table & structure parameters, and according to that you have to pass values and retrieve response. In second function it will return ticket n° after successfull insertion of ticket in solman.
I hope this sample code will help you, it worked for me.

I have a pig script with code like :
scores = LOAD 'file' as (id:chararray, scoreid:chararray, score:int);
scoresGrouped = GROUP scores by id;
top10s = foreach scoresGrouped{
sorted = order scores by score DESC;
sorted10 = LIMIT sorted 10;
GENERATE group as id, sorted10.scoreid as top10candidates;
};
It gets me a bag like
id1, {(scoreidA),(scoreidB),(scoreIdC)..(scoreIdFoo)}
However, I wish to include the index of items as well, so I'd have results like
id1, {(scoreidA,1),(scoreidB,2),(scoreIdC,3)..(scoreIdFoo,10)}
Is it possible to include the index somehow in the nested foreach, or would I have to write my own UDF to add it in afterwards?
For indexing elements in a bag you may use the Enumerate UDF from LinkedIn's DataFu project:
register '/path_to_jar/datafu-0.0.4.jar';
define Enumerate datafu.pig.bags.Enumerate('1');
scores = ...
...
result = foreach top10s generate id, Enumerate(top10candidates);
You'll need a UDF, whose only argument is the sorted bag you want to add a rank to. I've had the same need before. Here's the exec function to save you a little time:
public DataBag exec(Tuple b) throws IOException {
try {
DataBag bag = (DataBag) b.get(0);
Iterator<Tuple> it = bag.iterator();
while (it.hasNext()) {
Tuple t = (Tuple)it.next();
if (t != null && t.size() > 0 && t.get(0) != null) {
t.append(n++);
}
newBag.add(t);
}
} catch (ExecException ee) {
throw ee;
} catch (Exception e) {
int errCode = 2106;
String msg = "Error while computing item number in " + this.getClass().getSimpleName();
throw new ExecException(msg, errCode, PigException.BUG, e);
}
return newBag;
}
(The counter n is initialized as a class variable outside the exec function.)
You can also implement the Accumulator interface, which will allow you to do this even if your entire bag won't fit in memory. (The COUNT built-in function does this.) Just be sure to set n = 1L; in the cleanup() method and return newBag; in getValue(), and everything else is the same.
