How does static methods in interfaces impact performance or memory usage?

Static methods in interfaces provide a way to define utility functions that can be called without the need for an instance of the interface. This can impact performance and memory usage in several ways:

  • Reduced Memory Overhead: Since static methods belong to the interface itself, they don't require an instance, reducing memory consumption when functions are accessed frequently.
  • Improved Performance: Calling a static method generally has lower overhead compared to instance method calls. This can lead to performance boosts in scenarios where the methods are used frequently.
  • Enhanced Clarity: Interface static methods help in creating clear utility functions, separating them from instance behaviors, which can lead to faster code comprehension and maintenance.

However, it is essential to use static methods judiciously, as over-reliance may lead to a less flexible design that can be harder to extend in the long run.
