java - Accessing Classes from another class -

-

Considering that I am not using any IDE to create / run my Java code. But using Notepad and Command Prompt is compiling and running.

Can I safely assume: unless I keep my class files in the same folder, they always without informing the package Be able to "see" each other?

I came from another link with the same question title: But this is a different asking thing and the answer is in the context of the IDE, and use the CLASSPATH to use the IDE .

I intend to find out here which is JVM's behavior without an IDE

QUE: Can I safely assume that classes Can always "put each other" by putting them in the same folder?

There is something to eat here for your thoughts: -)

Suppose We have two versions of the same file

version 1 

  package mypack; Public Class Mayclass {public static zero major (string [] args) {System.out.println (1); }}

version 2 

  package mypack; Public class micro {public static zero main (string [] args) {System.out.println (2); }}

Compile version 2 like this 

  [leoks @ x ~] $ javac mypack / MyClass.java [leoks @ x ~] $ Java mypack .myClass 2

Then create a jar with version 1 and save it as "myjar.jar"

Try now 

  [leoks @ x ~] $ java -cp myjar.jar:. Mypack.MyClass 1 [leoks @ x ~] $ java -cp: Myjar.jar mypack.MyClass 2

As you can see, Classloader does not care. It only takes first class and ignores the other.

It is therefore not a matter of folders . This is about the package related to the JVM package, which can be inside the directory organization or within the jar.

c# - WPF Expander overlay used in ItemsControl -

-
I've been searching for a while, but all the solutions I can only deal with parts of my issue. With an item control, which includes the expansion, upon expansion, the content of the extensioner should be shown as an item which is overlapping the other item in the item control and not taking them down. The following XAML-code is actually a big problem: the content of the expansion does not overlap other objects but is hidden behind them, I think it is because of ZIndex because the following in ItemsControl Items are added after expander content. I managed to set a single spreader's ZIndex 99 style triggers, but it appears to be very complicated and error-prone solution any thoughts? & lt; Window x: orbit = "wpfTest.MainWindow" xmlns = "http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns: x = "http://schemas.microsoft.com/winfx/2006/ Xaml "title =" main window "height =" 350 "width =" 525 "...
