Java extracts code examples of the same and different elements in 2 collections

The sample code implementation shared in this article extracts the same and different elements in two collections

Here, you need to use a method provided by the collection collection: removeAll (cell list). The removeAll method is used to remove all elements contained in the specified collection from the list.

Syntax removeAll (collection C)

c: Contains a collection object that removes elements from the list.

The return value of this method is a Boolean object. If the list collection object changes due to calling the removeAll method, it returns true. Otherwise, it returns false. The implementation code is as follows:

Operation results:

_ Second does not exist in_ [happy, sun, good] in set_ Second exists in_ [Jack] in set

summary

The above is all about the code examples of the same and different elements extracted from the two sets in Java. I hope it will be helpful to you. If there are deficiencies, please leave a message to point out. Thank you for your support!
