To get a sublist of a list in Java, you can use the subList method of the List interface. This method takes two arguments: the starting index (inclusive) and the ending index (exclusive) of the sublist, and returns a view of the list that includes the elements between the specified indices.
Here's an example of how to use the subList method to get a sublist of a List object:
List<String> list = Arrays.asList("apple", "banana", "cherry", "date", "elderberry");
List<String> sublist = list.subList(1, 4); // sublist is ["banana", "cherry", "date"]
In this example, we're getting a sublist of the list object that includes the elements at indices 1, 2, and 3 (the second, third, and fourth elements).
Note that the subList method returns a view of the list, not a new list. This means that any changes made to the sublist will be reflected in the original list.
You can find more information about the subList method and examples of how to use it in the Java documentation.
