从列表中删除子列表 (Removing SubList from a List)

Suppose, we have a list of few elements like this,

假设我们列出了一些这样的元素，

list = [10,20,30,40,50]

From the list, we have to delete a sub list between sourcing_index (inclusive) and destinating_index (exclusive).

从列表中，我们必须删除sourcing_index (包括)和destinating_index (排除)之间的子列表。

This can be done by two ways,

这可以通过两种方式完成：

1. By Using subList(int sourcing_index, int destinating_index) and clear() method of interface.

   通过使用接口的subList(int sourcing_index，int destinating_index)和clear()方法。

2. By Using removeRange(int sourcing_index, int destinating_index) method of List interface.

   通过使用List接口的removeRange(int sourcing_index，int destinating_index)方法。

subList(int sourcing_index，int destinating_index)和clear()的列表 (subList(int sourcing_index, int destinating_index) and clear() of List)

This method is available in List interface.

在列表界面中可以使用此方法。

Syntax:

句法：

subList(int sourcing_index, int destinating_index);

We pass two parameters in the method of the List,

我们在List方法中传递两个参数，

• Sourcing_index is the selection of the starting point of the subList.

  Sourcing_index是子列表起点的选择。

• Destinating_index is the selection of the ending point of the subList.

  Destinating_index是对子列表终点的选择。

Example:

例：

import java.util.*;public class DeleteSublist {
       public static void main(String[] args) {
           LinkedList list = new LinkedList();        // use add() method to add elements in the list         list.add(10);        list.add(20);        list.add(30);        list.add(40);        list.add(50);        //  Current list Output        System.out.println("The Current list is:" + list);        // We will delete sublist by using subList(int,int)         // and clear() method of List.        list.subList(2, 4).clear();        //  New list Output after implementation of         // subList() and clear() method.        System.out.println("The New list is:" + list);    }}
