Where can I choose which .java to execute when running an Android Studio test?
I have 3 .java files and only one is being executed.
When searching the project for references for the specific .java which runs every time, I've only found the file name in workspace.xml file which is probably irrelevant.
private ClientIdentifier(final Client client, final CodeValue documentType, final String documentKey,final LocalDate validity, final String description) {
this.client = client;
this.documentType = documentType;
this.documentKey = StringUtils.defaultIfEmpty(documentKey, null);
i am confused in this part //this.validity = LocaleUtils.defaultIfEmpty(validity,null);
this.description = StringUtils.defaultIfEmpty(description, null);
}
I am passing LocalDate but don't know which utility to use for checking defualtIfEmpty
i have mainreport and subreport , where main report is getting printed in jasper, but not the subreport, see below code for subreport
<jr:list xmlns:jr="http://ift.tt/1cl9b3L" xsi:schemaLocation="http://ift.tt/1cl9b3L http://ift.tt/1cl9b3P" printOrder="Vertical">

</subreport>
</frame>
</jr:listContents>
</jr:list>
i have debugged the code and see there are no issues in generating the report.
i am passing customer order which contains customer details and list of orders. snippet of my customer bean
public class Customer {
private String customerName;
private List<Order> customerOrderList
}
and below code used to generate the report
List<OrderDeclarationBO> orderDeclarationBOLst = new ArrayList<>();
orderDeclarationBOLst.add(orderDeclarationBO);
InputStream in = this.getClass().getResourceAsStream("order.jrxml");
InputStream jasperIn = this.getClass().getResourceAsStream("order.jasper");
JasperCompileManager.compileReport(in);
JasperPrint jasperPrint = JasperFillManager.fillReport(jasperIn, new HashMap<String, Object>(), new JRBeanCollectionDataSource(orderDeclarationBOLst));
JasperExportManager.exportReportToPdfFile(jasperPrint, "orderInvoice.pdf");
need help, and dont know what is still required to print subreport.
EDIT :- Adding image of the report, where i am getting null values inside sub report, and not aligned properly
I have the following:
abstract class A extends Class C (abstract class C extends D).
private String name="";
public void setFff(double val) {
double old = fff.getAvg();
fff.update(val);
ListIterator<Observer> it = fffListeners.listIterator();
String ss;
while (it.hasNext()) {
ss = name + this.toString();
it.next().update("fff", fff.getValue(), fff.getAvg(), ss);
}
}
class B extends D implements Observable
private String name="";
public void notifyObservers() {
for(Observer observer:fffListeners){
v=fff.getValue();
m=fff.getAvg();
observer.update("fff", v, m, (name+this.getName()));
}
}
interface Observer:
void update(String nn, double bbb, double aaa, String nameThraed);
abstract class E implements Observer
class G extends E.
update in class G is the following
public void update(String string, double v, double m, String s) {
if ((B.getClass == "G")
&& string.equals("fff")&& (s.equals("B"))) {
this.fffList.add(m);
System.out.println("List of fff :" + fffList);
}
myMethod(fffList);
}
I want to get all the value of m and put theme in the list fffList when I get a notification from E. How can i do that?
I always thought hat HashMap is identifying its keys by using hasCode and equals. But this code still does not give me the value back. What am I missing?
import java.util.HashMap;
import java.util.Map;
/**

public class TypePair {
private final Class a;
private final Class b;
public TypePair(Class a, Class b) {
this.a = a;
this.b = b;
}
public TypePair(Object a, Object b) {
this.a = a.getClass();
this.b = b.getClass();
}
public boolean isPair (Object a, Object b) {
return this.a.isAssignableFrom(a.getClass()) && this.b.isAssignableFrom(b.getClass());
}
@Override
public boolean equals(Object obj) {
if (obj instanceof TypePair) {
return a.isAssignableFrom(((TypePair) obj).a) && b.isAssignableFrom(((TypePair) obj).b);
} else {
return false;
}
}
@Override
public int hashCode() {
return 1;
}
public static void main(String[] args) {
TypePair a = new TypePair(Number.class, String.class);
TypePair b = new TypePair(12, "hello");
Map<TypePair, Boolean> test = new HashMap<>();
test.put(a, true);
System.out.println(a.hashCode() == b.hashCode());
System.out.println(a.equals(b));
System.out.println("und? " + test.get(a));
System.out.println("und? " + test.get(b));
}
}
Prints
true
true
und? true
und? null
I am trying to use SimpleXML in non strict mode but the only thing that seems to work is to put required=false on every single field. Using false in read or in @Root doesn't seem to turn off strict mode.
MyClass myclass = serializer.read(MyClass.class, new File(args[0]), false);
Results in..
org.simpleframework.xml.core.ValueRequiredException: Unable to satisfy @org.simpleframework.xml.Attribute(name=, required=true, empty=)
I am using SimpleXML java v2.7.1 under Java 1.8.
Any ideas why?
Why is there a need to check ArrayIndexOutOfBounds in FileInputStream in java? This same code is given as an example in a book for core java.
FileInputStream fis;
try{
fis=new FileInputStream("inputFIle.txt");
}catch(FileNotFoundException e){
System.out.println("File was not found");
}catch(ArrayIndexOutOfBoundsException e){
e.printStackTrace();
}
