java入门的几个代码,很实用,初学者不可错过

public class SinglyLinkedListElement  //单向链结点类
{
  protected Object data;     //结点的内容，其类型为Object,它是一切类的父类
  protected SinglyLinkedListElement nextElement;  //指示其后续结点
  public SinglyLinkedListElement(Object v, SinglyLinkedListElement next) //构造单向链结点
// 对象
  {
data=v;                
nextElement=next;
  }

  public SinglyLinkedListElement(Object v)   //构造单向链结点对象

  {
data=v;
nextElement=null;

  }

  public SinglyLinkedListElement  next()   //获取next
  {
    return nextElement;
  }

  public void setNext(SinglyLinkedListElement next)   //设置next
  {
    nextElement=next;
  }

  public Object value()   //获取结点内容

  {
    return data;
  }

  public void setValue(Object value)  //设置结点内容
  {
