abstract - Using extends in Java gives enclosing instance error -

-

I am trying to use expansion in Java. I created a quick table to expand in detail. , And then extended it. However my IDE is now saying that "A brief example that requires abstract_class" and provides my constructor with major error rows for derivative organs. What is happening on the earth? The intangible class does not need any kind of constructor.

For reference, I am using the extension rather than the tools in the part because the implementation details which I do not want include every derived class which equally uses the reflection on it.

Edit: I have read some responses, what is a static (or non-static, for that matter) class in the name of God? And just to bother you all, did not solve this problem. 

  // some_class.java public class some_class {public static abstract class abstract_class {...} ...} / / model Java public class model in some_class.abstract_class {public model (...) {// There is no ending example! serious error. ...} ...}

And I thought that C ++ header files were bad.

The code you posted seems to be compiling exactly for me to make a clean build in our IDE Try and it should work.

For just your curiosity, there are 2 types of internal squares in Java: static and regular or ( non static ). If you do not include the static keyword for internal category definition, then this means that the example of that class will always require an example of parent class. For pre: 

  public class MyClassOuter {// ... public class MyClassInner {// ..}}

If you write it down, So it is understood that any example of MyClassInner MyClassOuter There will be an implicit reference to another example of

static ; hand is not such a thing; it is just a definition of a class that is contained within another category definition The external class is used almost like a package (though not quite).

Obfuscating Python code? -

I'm looking for a way to hide my Python source code. print "Hello World!" How can I encode this example so that it is not human-readable? I have been asked to use Base 64 but I'm not sure how. itemprop = "text"> It is limited only, first level ambiguous resolution, but has built-in: byte-code in Python Is a compiler for: dragon-o-m py_compile & lt; Your program.py & gt; creates a .pyo file with a byte-code, and where the docstrings are removed, etc. You can rename .pyo with the .py extension, and python & lt; Your program.py & gt; runs as your program, but it does not have your source code. PS : If your program blur modules like this, you need to rename them with the .pyc suffix (I Not sure it will not break a day), or you can work with .pyo and run them with python -o ... .pyo ( Import should work). This will allow dragon to search your modules (otherwise, Python looks for the .py module).
