小第要寫一個用java寫成的鏈結串列(LinkedList)，要有增加，刪除，搜尋的功能(要能由使用者輸入)，但只會寫出一個功能一個程式的檔，不知那位大大能把它合併成一個程式。謝謝啦!! 原始檔:    //新增 import java.util.*; public class listadd  {    public static void main(String args[])  {     int n=1,m=4; String num[]={"1","2","3","stop"}; LinkedList Id=new LinkedList(); System.out.println("在鏈結串列中插入9!"); while(n<=m) { Id.addLast(num[n-1]); n++; } Id.add(2,"9");  while(Id.getFirst()!="stop") { System.out.print(Id.getFirst()+"->"); Id.removeFirst(); } System.out.print("null");    } } //刪除 import java.util.*; public class listdel  {    public static void main(String args[])  {  int n=1,m=4; String num[]={"1","2","3","stop"}; LinkedList Id=new LinkedList(); System.out.println("刪除鏈結串列中間元素!"); while(n<=m) { Id.addLast(num[n-1]); n++; }  Id.remove(2);  while(Id.getFirst()!="stop") { System.out.print(Id.getFirst()+"->"); Id.removeFirst(); } System.out.print("null"); } } < >< >

import java.io.*; import java.util.*; public class MyTestLinkedList { public static void main(String[] args) { BufferedReader in = new BufferedReader(new InputStreamReader(System.in)); LinkedList list = new LinkedList(); while (true) { System.out.print("(L)ist, (A)dd, (D)elete, (Q)uit?:"); try { switch (in.readLine().charAt(0)) { case 'L': for (int i = 0; i < list.size(); i ) { System.out.println(list.get(i)); } break; case 'A': System.out.print("Input String to Add:"); list.add(in.readLine()); break; case 'D': System.out.print("Input Index to Delete:"); list.remove(Integer.parseInt(in.readLine())); break; case 'Q': System.exit(0); break; } } catch (IOException ex) { ex.printStackTrace(); } } } }
