The 'transient' keyword in Java

• transient on a field means it won't be serialized
  • those fields will have their default values when deserialized
• use cases
  • derived or calculated fields
  • non-serializable references
  • fields that do not represent the state of the object
  • sensitive data you don't want to send over the network
• when paired with the final keyword and newing-up (neither baeldung nor geeksforgeeks suggests a use-case for pairing these keywords)
  • if right hand side is a literal, value will be that literal
  • if a e.g. new String(...), value will be null
