In object-oriented computer programming, SOLID is a mnemonic acronym for five design principles intended to make software designs more understandable, flexible and maintainable. The principles are a subset of many principles promoted by American software engineer and instructor Robert C. Martin. SOLID represents principles of class design, yet many Java developers are not aware of them.

For this meetup we’ll have 5 short presentations about SOLID principles, with examples in Java. Our presenters are:

• Single responsibility principle, Branislav Čolaković [slides] [code]
• Open–closed principle, Vladimir Ilić [slides]
• Liskov substitution principle, Dijana Lukić [slides] [code]
• Interface segregation principle, Petar Becić [slides] [code] and
• Dependency inversion principle, Dragan Raković [slides].

After that, we’ll have a discussion and a raffle, where you’ll have a chance to win free JetBrains license (for IntelliJ IDEA Ultimate or other JetBrains IDE) and a ticket to jPrime 2019, Java conference in Sofia, 28.-29. May 2019.
