Effective Java Study Note - Consider static factory methods instead of constructors

There are advantages of static factory methods, you can have name for the method, to make its usage more clear; or you can hide the implementation; you don't even create a new instance when the method invoked. There're many common names used for the static factory methods as mentioned below.

• from
• Date.from(instance)
• of
• EnumSet.of(A, B, C)
• valueOf
• Integer.valueOf(100)
• instance
• getInstance
• create
• newInstance
• getType
• FileStore fileStore = Files.getFileStore(path)
• newType
• BufferedReader bufferedReader = Files.newBufferedReader(path)
• type
• Collections.list(data)
