java字符串刪掉子串

從列表中刪除子列表 (Removing SubList from a List)

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

假設(shè)我們列出了一些這樣的元素，

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

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

從列表中，我們必須刪除sourcing_index (包括)和destinating_index (排除)之間的子列表。

This can be done by two ways,

這可以通過兩種方式完成：

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

通過使用接口的subList(int sourcing_index，int destinating_index)和clear()方法。

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

通過使用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,

我們?cè)贚ist方法中傳遞兩個(gè)參數(shù)，

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

  Sourcing_index是子列表起點(diǎn)的選擇。

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

  Destinating_index是對(duì)子列表終點(diǎn)的選擇。

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 OutputSystem.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);} }

Output

輸出量

E:\Programs>javac DeleteSublist.javaE:\Programs>java DeleteSublist The Current list is:[10, 20, 30, 40, 50] The New list is:[10, 20, 50]

removeRange(int sourcing_index，int destinating_index) (removeRange(int sourcing_index, int destinating_index))

This method is available in List interface.

在列表界面中可以使用此方法。

removeRange(int sourcing_index, int destinating_index);

We pass two parameters in the method of the List,

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

  Destinating_index是對(duì)子列表終點(diǎn)的選擇。

Example:

例：

import java.util.*;public class DeleteSublist extends LinkedList {public static void main(String[] args) {DeleteSublist list = new DeleteSublist();// 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 OutputSystem.out.println("The Current list is:" + list);// We will delete sublist by using removeRange(int,int) // method of List.list.removeRange(2, 4);// New list Output after implementation of // removeRange(int,int) method.System.out.println("The New list is:" + list);} }
