Code Examples about Design Patterns

In this Repository we collect example design patterns in Java and C++.

Java Examples

We use Apache Maven to build Java Examples.
We use Junit for unit test.
We use findbugs for static code analysis. We use the maven plugin for findbugs
We use checkstyle to check our code style. We use the maven plugin for checkstyle

We use CMake to build C++ code.

Use Smart pointer in C++
Use C++14
Use one of the compiler LLvm - clang, 'Gnu Compiler Collection' gcc or 'Gnu C Compiler' g++, and enable warning flags while compiling your code
Check Memory Leaks using valgrind

valgrind --tool=memcheck <your_app> <your_apps_params>

Videos by Christopher Okhravi describing examples form Head First Design Patterns Book
If you program C++, I highly Recommend Videos by Bjarne Stroustrup. For examples on CppCon, CppCon 2017, Keynotes by Bjarne Stroustrup . (BTW, this line should be on top of top of this list :) )
