2.尾插法创建链表_java

创建节点

package list;

public class HeroNode {
	private int no;
	private String name;
	private String nickname;
	private HeroNode next;
	public HeroNode() {
		super();
		// TODO Auto-generated constructor stub
	}
	//构造器
	public HeroNode(int no, String name, String nickname) {
		super();
		this.no = no;
		this.name = name;
		this.nickname = nickname;
	}
	
	public int getNo() {
		return no;
	}
	public void setNo(int no) {
		this.no = no;
	}
	public String getName() {
		return name;
	}
	public void setName(String name) {
		this.name = name;
	}
	public String getNickname() {
		return nickname;
	}
	public void setNickname(String nickname) {
		this.nickname = nickname;
	}
	public HeroNode getNext() {
		return next;
	}
	public void setNext(HeroNode next) {
		this.next = next;
	}
	@Override
	public String toString() {
		return "HeroNode [no=" + no + ", name=" + name + ", nickname=" + nickname +  "]";
	}
	
	

}

*创建链表*
```java
package list;


public class HeroList {//尾插法
	//初始化头结点，为了保证Head不被修改，这里就只设置了get方法
	private HeroNode head = new HeroNode(0, null, null);
	
	
	public HeroNode getHead() {
		return head;
	}

	//添加节点到尾部
	public void add(HeroNode hero) {
		//找到最后一个节点
		HeroNode temp;
		temp = head;
		while(temp.getNext() != null) {
			//找到最后的节点
			temp = temp.getNext();
		}
		temp.setNext(hero);
	}
	
	//判断链表是否为空
	public boolean isEmpty() {
		if(this.getHead().getNext() == null) {
			return true;
		}
		return false;
	}
	
	//修改节点
	public void updateByNo(HeroNode newHero) {
		int no = newHero.getNo();
		if(this.isEmpty()) {
			System.out.println("链表为空！");
			return;
		}
		HeroNode temp = head.getNext();
		while(temp != null) {
			if(temp.getNo() == no) {
				temp.setName(newHero.getName());
				temp.setNickname(newHero.getNickname());
				System.out.println("修改成功");
				return;
			}
			temp = temp.getNext();
		}
		System.out.println("未找到该节点");
	}
	
	//删除节点
	public void deleteByNo(int no) {
		if(this.isEmpty()) {
			System.out.println("链表为空！");
			return;
		}
		HeroNode temp = head;
		while(temp.getNext() != null) {
			if(temp.getNext().getNo() == no) {
				temp.setNext(temp.getNext().getNext());
				System.out.println("删除成功");
				return;
			}
			temp = temp.getNext();
		}
		System.out.println("未找到该节点");
		
	}
	
	//显示节点
	public void showHero() {
		HeroNode temp = this.head.getNext();
		if(this.isEmpty()) {
			System.out.println("链表为空");
			return;
		}
		while(temp != null) {
			System.out.println(temp);
			temp = temp.getNext();
		}
	}
}
