Effective Java Notes

Creating and Destroying Objects

Item 1: Consider static factory methods instead of constructors

• One advantage of static factory methods is that, unlike constructors, they have names
• A second advantage of static factory methods is that, unlike constructors, they are not required to create a new object each time they’re invoked
• A third advantage of static factory methods is that, unlike constructors, they can return an object of any subtype of their return type
• The main disadvantage of providing only static factory methods is that classes without public or protected constructors cannot be subclassed

Android Developer Toolbox - Notes

Gradle

• Create different build variants which contain different code of your app
  • Internal - for the company. Embed a lot of tools to locate issues easily.
  • Production - only for customers

Redux Rules

1. Immutable state - it should not be changeable instead is replaced. Everything that changes in your app including the date and the UI state is stored in a single object tree.
2. State is read only - to make a change you need to dispatch an action. An action is a plain javascript object. State = data, change = action

Pure vs Impure functions

1. Pure 2. Depend only on their input params 3. Some value for some input elements
