Memory Consumption

Another disadvantage of using OOP features in Java is that it can increase memory consumption. Object-oriented designs tend to involve the developer creating multiple objects, for which memory must be allocated. If we compare this to procedural programming, which can be more memory-efficient, OOP has the potential to consume more memory due to object storage needs. Memory management techniques like garbage collection can lessen memory-related issues and Java’s runtime environment (JRE) automatically handles memory optimizations, so again, as with performance overhead, this may be a negligible difference.
