先构造 节点对象Node
/*
*链接点,相当于车厢
*/
public class Node {
//数据域
public long data;
//指针域
public Node next;
public Node(long value){
this.data = value;
}
/*
*显示方法
*/
public void display(){
System.out.print(data + " ");
}
}
再构造 链表对象Linklist,现实方法删除插入:
/*
*链表,相当于车头
*/
public class Linklist {
//头结点
private Node first;
public Linklist(){
first = null;
}
/*
* 插入一个节点,在头结点后进行插入
*/
public void insertFirst(long value){
Node node = new Node(value);
node.next = first;
first = node;
}
/*
* 删除一个节点,在头结点后进行删除
*/
public Node deleteFirst(){
Node tmp = first;
first = tmp.next;
return tmp;
}
/*
* 显示方法
*/
public void display(){
Node current = first;
while(current != null){
current.display();
current = current.next;
}
System.out.println();
}
/*
* 查找方法
*/
public Node find(long value){
Node current = first;
while(current.data != value){
if(current.next == null){
return null;
}
current = current.next;
}
return current;
}
/*
* 删除方法,根据删除域来进行删除
*/
public Node delete(long value){
Node current = first;
Node previous = first;
while(current.data != value){
if(current.next == null){
return null;
}
previous = current;
current = current.next;
}
if(current == first){
first = first.next;
}else{
previous.next = current.next;
}
return current;
}
}
测试:
public class TestLinkList {
public static void main(String[] args) {
Linklist linkList = new Linklist();
linkList.insertFirst(34);
linkList.insertFirst(23);
linkList.insertFirst(12);
linkList.insertFirst(-1);
linkList.insertFirst(0);
// linkList.display();
//
// linkList.deleteFirst();
// linkList.display();
//
// Node a = linkList.find(12);
// a.display();
linkList.delete(34);
linkList.display();
}
}
