<\/span><\/h3>\nNo, ArrayLists in Java do not pass by value. They actually pass the reference to the ArrayList object. This means that when an ArrayList is passed as a parameter to a method, any changes made to the ArrayList inside the method will affect the original list.<\/p>\n
Let’s illustrate this with an example:<\/p>\n
“`java
\nimport java.util.ArrayList;
\nimport java.util.List;<\/p>\n
public class ArrayListPassingExample {
\n public static void main(String[] args) {
\n List names = new ArrayList<>();
\n names.add(“Alice”);
\n names.add(“Bob”);<\/p>\n modifyList(names);<\/p>\n
System.out.println(names);
\n }<\/p>\n
private static void modifyList(List list) {
\n list.add(“Charlie”);
\n list.add(“David”);
\n }
\n}
\n“`<\/p>\nRunning this code will output: `[Alice, Bob, Charlie, David]`. As you can see, the `modifyList` method takes an ArrayList as a parameter and adds two names to it. When the `main` method prints the names list after calling `modifyList`, the changes made to the list are reflected.<\/p>\n
