Does anyone know of a good JUnit test generation tool?

Can anyone please help me to provide a Java code for privacy compatibility matching algorithm?

I looking for open-source tool for reverse engineering Android mobile apps that generate UML models. 

Dependency injection (DI) is a great pattern/principle to make code better configurable and testable. 

Using a framework (in Java) such as Guice (or any other JSR 330 implementation), or some other so called "inversion of control (IOC) container", really simplifies using DI. But even the most simple usages are often problematic. E.g. (with an JSR330 annotation with field injection):

class C {  @Inject X x; }

This class must not be created via new in normal client code, because then x cannot be injected. Also, assuming X is an interface, there needs to be a configuration (binding) for X.

I'm wondering if there exist any work on verifying these kind of situations. Are there any IDEs or tools implementing such verification (e.g., creating at least a warning if, given the example above, C is created via new or if no binding for X is detected)? Of course there are many more problems, such as DI cycles etc. 

Do yo know any research addressing these and other issues?

So far, I have only found a single paper [HH13], but this paper only scratches the surface. It defines two constraints which are to be satisfied: Compatibility (a binding T to an injected type D must be a subtype: T<:D) and completeness (for all D: exists binding T). Unfortunately, the paper does not handle cases such as scoping, multiple modules etc. And even the simple case of new constructor call as shown in the example is not handled.

I am doing atm gui for my project in java. In my opinion using array of objects is the best option to store customer data. When i try to access it in an ActionListener method, i get this error: Exception in thread "AWT-EventQueue-0" java.lang.NullPointerException. This happens when i hit the register button. I tried to delete the array and use a normal object in the ActionListener and it worked smoothly but it is not useful to store multiple customer data. Is there another way to store these or to fix this error? I uploaded the source file so you can check the code. Thanks in advance.

Students often ask if it is easier and faster to implement data structures, such as list, stack, queues, trees, forest, in Java or C++?

Which of these is your own choice? Java or C++?

Your answers will be appreciated. Thank you in advance.

Is recursive implementation faster in Java than in C++ ? For instance; in the implementation recursive functions for Fibonacci sequences or that of Towers of Hanoi, which of the programming languages will run faster and under the shortest possible time? Java or C++ ?

I have a localhost server written in Java and let's say it generates data continuously. My purpose is to send that data to JavaScript. I want to use that data for a web application. I have been looking at AJAX/Jquery, LiveConnect, etc. but couldn't find any correct direction. Can anyone suggest something?

Hello Scholars,

I am trying to make a common domain for input and output of a function. I divide this domain in input scheme and output scheme.

Input scheme contains a set of possible inputs of a function and output schemes contain a set of possible outputs of a function.

For example: function parameter, global variables, inFile pointer are members of input scheme and return variable, reference variable, outFile pointer are member of output scheme.

My question is what else can we add in this domain? These members can be dependent or independent.

Can i add i/o device in this domain?
