In Java, SubList is a method of the List interface that is used to obtain a sublist of the original list. The sublist is a view of the original list, referencing a portion of its elements. The sublist is mutable, and any modifications made to the sublist will be reflected in the original list.<\/p>\n

Here is how to use SubList:<\/p>\n

    \n
  1. To create a sublist: You can use the subList method of the List interface to create a sublist. This method takes two parameters, the starting index (inclusive) and the ending index (exclusive). For example, to get the first three elements of the original list, you can use List.subList(0, 3).<\/li>\n
  2. To access elements of a sublist, which is a view of the original list, you can use the get method to retrieve the element at a specific index. For example, to access the first element of the sublist, you can use subList.get(0).<\/li>\n
  3. Edit sublists: Changes made to the sublist will be reflected in the original list. You can use the set method to modify the value of a specific element at a particular index in the sublist. For example, to change the first element of the sublist to a new value, you can use subList.set(0, newValue).<\/li>\n
  4. Adding Elements: You can use the add method to add elements to a sublist. After adding an element, the original list will also increase accordingly. For example, to add a new element to the end of a sublist, you can use subList.add(newValue).<\/li>\n
  5. Remove elements: You can use the remove method to delete elements from a sublist. After deleting an element, the original list will decrease accordingly. For example, to delete the first element of a sublist, you can use subList.remove(0).<\/li>\n<\/ol>\n

    It is important to note that making structural changes to the original list, such as adding or removing elements, may cause the sublists to become invalid, resulting in a ConcurrentModificationException. Therefore, it is recommended to make a copy of the original list before modifying the sublists.<\/p>\n","protected":false},"excerpt":{"rendered":"
