SOLID 패턴

• SRP (Single Responsibility)
• OCP (Open/Closed)
• LSP (Liskov Substitution)
• ISP (Interface Segregation)

• DIP (Dependency Inversion)

  class Golang: Language {
      compile() {
          println("gopher")
      }
  }
  
  class Kotlin: Language {
      compile() {
          println("still on JVM")
      }
  }
  
  class Java: Language {
      compile() {
          println("legendary")
      }
  }
  

SRP (Single Responsibility)

• “should be open for extension, but closed for modification”

  fun run(language: Language) {
      language.compile()
  }
  val golang = Language(GOLANG)
  val kotlin = Language(KOTLIN)
  val java = Language(JAVA)
  
  run(golang)
  run(kotlin)
  run(java)
  

compile() function is open for extension, but closed for modification

LSP: Liskov Substitution

val golang = Language(GOLANG)
val kotlin = Language(KOTLIN)
val java = Language(JAVA)

ISP (Interface Segregation)

DIP (Dependency Inversion)
