What can be achieved through the use of generics in Java?

  1. Faster program execution

  2. Elimination of class hierarchies

  3. Compile-time type safety for collections

  4. Automatic garbage collection

The correct answer is: Compile-time type safety for collections

Because generics enable developers to specify the type of data contained within a collection at compile time, it ensures that only relevant data types can be added to the collection. This provides compile-time type safety, as any attempts to use a different data type will result in a compilation error. This feature helps to prevent runtime errors and improve code quality. Options A, B, and D are incorrect because generics do not directly impact program execution speed, eliminate class hierarchies, or control the automatic garbage collection process.
