假设subList1和subList2的大小分别为3和2,饼状图如下: 60%40%"Comparison Result"subList1subList2 5. 结语 通过本文的介绍,我们了解到如何在Java中比较两个ArrayList子集的大小。我们首先介绍了ArrayList的基本概念和子集的定义,然后详细阐述了比较方法和代码示例。最后,我们使用饼状图展示了比较结果,使结果更加直观。
Here’s a quick comparison of the methods we’ve discussed: Whether you’re new to Java or an experienced developer looking to deepen your understanding of ArrayList, we hope this guide has been a valuable resource. The ability to initialize an ArrayList effectively is a fundamental skill in J...

2.1. With Java 9 Since Java 9, we can use aList<E>.of(E… elements)static factory method to create an immutable list: @Test(expected = UnsupportedOperationException.class)publicfinalvoidgivenUsingTheJava9_whenUnmodifiableListIsCreated_thenNotModifiable(){finalList<String> list =newArrayList<>(...
In Java, the standard array has the fixed length, so, you must know the size of the array in advance. But, it may be the case that you may not know what length of the array you need until the run time. Hence, Collection framework introduced the ArrayList class to overcome this issue...

TheLinkedListimplementsDequeinterface as well, so it provides queue-likeFIFOfunctionality through methods such aspeek()andpoll(). As seen in the performance comparison,ArrayListis better for storing and accessing data.LinkedListis better for manipulating data. ...
In this quick article, we had a look at the ArrayList in Java. We showed how to create anArrayListinstance, how to add, find or remove elements using different approaches. As usual, you can find all the code samplesover on GitHub.
The LinkedList performs better when mutations are more in comparison to iterations. 12. Conclusion The Java ArrayList class is an excellent utility class to store elements in insertion order and perform various operations on them. Being part of the collection framework makes it even more attractive ...
