we couldn't use third-party libraries to do this task due to security regulations. So I devised an approach to compare two objects of the same type using the Java Reflections API. All we need to do is pass two objects to a method, and it will return the list of fields that ...
Alternatively, we can use Java Streams API to find common elements between two Lists. To do that, we can create a Stream of the first List and use thefilter()method to retain only the elements in the second List. Example of using Java Streams to find common elements between two Java Lis...
