c# - How to detect whether Java runtime is installed or not -

-

I program windows applications using Java and it creates the ".jar" file which is the ".exe" file is not. When a Java Runtime is not installed, the client computer opens the ".jar" file, then it runs as a store with winrar. To show the message box to the user to install the Java Runtime or to launch the ".jar" file using the Java Runtime, I need to know how to run the Java runtime or not, using the C # code. Whether or not the computer is installed on.

You can check the registry 

  Registry RK = Registry local machine; Registry all = RK OpenSubby ("software \\ Java soft \\ Java runtime environment"); String current virion = subkeygate value ("current version"). Toasting ();

MVP, design question -

-
I am working on an MVP designated application and there are some design questions: I presenter how to communicate while writing code in the layer Should go between different presenters / ideas? Let's say I have a window window with a window viewer and I want to set the window title on the window from the second window. I have a title-setter on the window view, which wraps the actual Gui title. Should I call the title-setter directly on the scene (window viewer.tit = "title") or should I wrap the view title as the presentation title setter (window-creator.tit = "title")? Ask yourself how you will test it? If you do a window presentation. View. Tight = "Title", how can you test that the presenter is setting the title?

java - Is there an object like a "Set" that can contain only unique string values, but also contain a count on the number of occurrences of the string value? -

There is an object like "set" in Java that can contain only unique string values, but it also includes a count Is the number of string value in number? This idea is simple. A data set, ALA ... ABBCCC I will set the text of each line set- I want to add to the object every time a non-unique text is added to the set, I also want to show a numeric value associated with the set to show how often it was added. So if I run it on the above data then set output will be something like this: A: 1B: 2C: 3 Any ideas? Maps & lt; String, integer & gt; add public null (strings) {if (map.containsKey (s)) {map.put (s, map.get (s) + 1); } And {map.put (S, 1); }}
