Traditional collections are widely used in today’s world because of their ease of use. They go through the hassle-free process of data structure manipulation whereas concurrent collections in java has to meet two important challenges before they can be used for memory management i.e., it should provide optimal performance as compared to the traditional collection and it should not require any synchronization during data structure manipulation because a thread starvation problem may occur otherwise which will negatively affect its performance.
In short, the concurrent collections in Java is an optimized version of traditional collections which don’t have any kind of issues related to the synchronization mechanism employed by traditional collections because this synchronization has a negative impact on their performance as compared to those of concurrent collections in java.

Traditional Collections
Traditional collections are widely used in today’s world because of their ease of use. They go through the hassle-free process of data structure manipulation whereas concurrent collection has to meet two important challenges before they can be used for memory management i.e., it should provide optimal performance as compared to the traditional collection and it should not require any synchronization during data structure manipulation because a thread starvation problem may occur otherwise which will negatively affect its performance.
Concurrent Collections
Concurrent collections are free of all these issues and can be used without any fear of performance degradation. This is the first difference between traditional collections and concurrent collections in java.
The second notable difference between traditional collections and concurrent collections in java is that the concurrent collection does not use locks for accessing data structure elements whereas traditional collection uses a standard synchronized mechanism to access all their data structure elements which causes a thread starvation problem.
In other words, we can say that the synchronization mechanism employed by the traditional collection has a negative impact on their performance as compared to those of concurrent collection.
Traditional collections vs Concurrent collections
Traditional collections provide optimal performance as compared to traditional collection because it doesn’t require any synchronization during data structure manipulation.
A concurrent collection is an optimized version of traditional collections which don’t have any kind of issues related to the synchronization mechanism employed by traditional collections because this synchronization has a negative impact on their performance as compared to those of concurrent collection.
The difference between the two types of collections is that the concurrent collection does not use locks for accessing data structure elements whereas traditional collection uses a standard synchronized mechanism to access all their data structure elements which causes a thread starvation problem in case multiple threads require the same resources, resulting in inferior performance.
It is recommended that you should use Concurrent collection in a high-performance application which is likely to handle multiple tasks simultaneously because the traditional collection can make it difficult for the user to access and manipulate data structure elements whereas concurrent collection provides a simple, easy and highly optimized set of methods for manipulating data structures.
In short, we can say that the synchronization mechanism employed by the traditional collection has a negative impact on their performance as compared to those of concurrent collection.
Conclusion
In this article, we have described the differences between concurrent collections and traditional Collections in java. These collections are highly optimized for high-performance applications which handle multiple tasks at a time.
The traditional collection has a standard synchronization mechanism employed by it which causes a thread starvation problem if multiple threads require the same resources, resulting in inferior performance whereas concurrent collection does not use locks for accessing data structure elements and provides a simple, easy, and highly optimized set of methods for manipulating data structures.
It is recommended that you should use Concurrent collection in high-performance applications because the traditional collection can make it difficult for the user to access and manipulate data structure elements.”
