java - int cannot be converted to Node -

i'm getting error:

incompatible types: int cannot converted node

why getting kind of error?

public void insertitem(int e) {   if(e<head.getitem())   {      addfirst(e);   }   else if(count==1)   {      addlast(e);   }   else   {      node newnode = new node(e);      node prev = head;      node p = prev.getitem();       while(p!=null)      {         if(e<p.getitem())         {            newnode.setlink(p);            prev.setlink(newnode);            p = p.getlink();            prev = prev.getlink();         }       }    } }    public class node {  private node link;  private int item;  public node(int item, node link) {   setlink(link);   setitem(item);  }  public node(int item) {   this(item, null);  }  public node() {    this(0, null);   } //empty node  public void setlink(node link) {   if (link != null) this.link = link;  }  public void setitem(int item) {   this.item = item;  }  public node getlink() {   return link;  }  public int getitem() {   return item;  }  public string tostring() {   return item + "";  } } 

i using getitem() class here is:

public class node {     private node link;     private int item;      public node(int item, node link)     {         setlink(link);         setitem(item);     }      public node(int item)     {         this(item, null);     }      public node()     {         this(0, null);     } //empty node public void setlink(node link){ if(link != null) this.link = link; } public void setitem(int item) // {this.item = item;} public node getlink(){return link;} public int getitem(){return item;} public string tostring(){return item+ "";} } 

as can see, node#getitem returns int value not node value.

so when trying write : node p = prev.getitem(); showing error.

maybe need : node p = prev.getlink();
