Problem using Linked list in java

[Aaliya Seth]

Hello,
I need help because I get errors that I can not fix. Being more precise i have a problem in the Linked List, I am trying it but I can not fix
Here is my code.

import java.util .*;
 
    Public class LinkedList{
	private Link hd = null;
	
	class Link{
	    private Link nxt;
	    private String ele;
	    
	    Public Link(String ele, nxt Link){
		this.ele = ele;
		this.nxt = nxt;
	    }
	}
	
	Public void add(String text){
	    hd = new Link(text, hd);
	}
	
	Public Intl size(){
	    Intl size = 0;
	    while(hd! = null){
		size + +;
hd = hd.nxt;
	    }
	}
	
	Public String toString(){
	    return ele + " " + nxt.function toString() {
    [native code]
}();
	}
    }

Hello,
Link, a class is an internal class and an attribute of your class LinkedList, therefore you access them with

LinkedList.list

I think you are not clear with the concept of the basic of java. I recommend you to read the basic tutorial or documentation on java , then try to write programs.

Hey
I have modified your code, see if it works now

import java.util .*;
 
    Public class LinkedList{
	private Link hd = null;
	
	class Link{
	    private Link nxt;
	    private String ele;
	    
	    Public Link(String ele, nxt Link){
		this.ele = ele;
		this.nxt = nxt;
	    }
	}
	
	Public void add(String text){
	    hd = new Link(text, hd);
	}
	
	Public Intl size(){
	    Intl size = 0;
	    while(hd! = null){
		size + +;
hd = hd.nxt;
	    }
	    return size;
	}
	
	Public String toString(){
	    StringBuilder sb = new StringBuilder();
sb.append("eles of the list:);
	    while(hd! = null){
		sb.append(hd.ele).append(" ");
hd = hd.nxt;
	    }
	    return sb.function toString() {
    [native code]
}();
	}
    }

Hello,
I advise you to make separate classes for Link and LinkedList is better for Conception. And then where is the method which displays your list and its size? The above post which is posted contains a code, see if the that works first and if not then post back with the error. But before then you have to try by your self first.

Hello,
Head represents an instance variable, change your method as follows

Public Intl sz(){
       Intl sz = 0;
       Link lk = head;
       while(lk! = null){
      sz + +;
       lk = lk.next;
       }
       return sz;
   }

But do not just copy / paste, try to understand why your original method did not work. If you have other questions to which you can not find a response mature reflection , Post them on the forum.

Hello,
This is my modified code, if you have any idea about it then please do post back , even this is not working

Public class Link{
    private Link nxt;
    private Final String ele;
    
    Public Link(String ele, nxt Link){
	this.ele = ele;
	this.nxt = nxt;
    }
    
    Public Link getnxt(){
	return nxt;
    }
    
    Public String getele(){
	return ele;
    }
}
