What does latent typing enable?

  1. Describing an operation without specifying the types it applies to

  2. Changing an object's type at runtime

  3. Creating type-safe collections

  4. Optimizing Java code performance

The correct answer is: Describing an operation without specifying the types it applies to

Latent typing enables declaring an operation without specifying the types it applies to. This allows for more flexibility and can simplify the code by not requiring explicit type declarations. Option B is incorrect because changing an object's type at runtime is a feature called dynamic typing, which is enabled by other programming languages like Python and JavaScript. Option C is incorrect because creating type-safe collections is a feature enabled by static typing, not latent typing. Option D is incorrect because latent typing does not have any impact on Java code performance. Instead, it is a feature of programming languages like TypeScript and Kotlin.
