This market predicts when the mainstream Java programming language will support Value Classes (also known as Value Types).
- A Value Type qualifies only if it meets the following criteria and is available as a language feature in a production-quality, mainstream JDK (Java Development Kit):
- Definition of Value Types: Value Types are a new kind of type in Java, designed to be lightweight, immutable, and without identity.
- They have the following characteristics:
- Immutability: Instances of Value Types are immutable, meaning their state cannot be changed after creation.
- Equality: Value Types support == for value-based equality, comparing their constituent values (at least as a default behavior).
