If you need to compare two lists of objects and want to perform a deep comparison, you can implement a custom method that iterates over the elements of the lists and compares them recursively. This approach all
Learn tocompare two ArrayListin Java to find if they contain equal elements. If both lists are unequal, we will find thedifference between the lists. We will also learn to find common as well as different items in each list. Note that the difference between two lists is equal to a third...
Java Stream: Finding Common Values in Two Lists In Java programming, the Stream API provides a powerful way to process collections of objects. One common task when working with collections is to find common values between two different lists. In this article, we will explore how to achieve thi...

Comparableinterface provides a single methodcompareTo(T o)to implement by any class so that two objects of that class can be compared. This method isused for implementing the natural sorting behavior. TheUserrecord after implementing theComparableinterface is as follows. The similar implementation can...
Lists (and arrays) of objects that implementthisinterfacecan be sorted automatically by Collections.sort (and Arrays.sort). Objects that implementthisinterfacecan be usedaskeysina sorted map oraselementsina sortedset, without the need to specify a comparator. ...
This quick tutorial demonstrated ways of testing if two Java Lists are equal. Two List implementations are considered equal when they have the same elements in the same order. We studied how to assert that the two Lists are the same or are equal using JUnit, TestNG, AssertJ, and plain Jav...
Now we useComparableinterface to sort objects. Main.java import java.util.Comparator; import java.util.List; class Card implements Comparable<Card> { @Override public int compareTo(Card o) { return Comparator.comparing(Card::getRank) .thenComparing(Card::getSuit) ...
