How to remove an item from LinkedList in java program?

[MAHAH]

Hello to all,
I am last year B.Sc.I.T. student. In our last exam in java paper one question has asked like How to remove an item from LinkedList in java program? I tried various tricks to solve this program but unable to get solution. Can anyone know how to write this program. Please help me.
Thank you.

Hey it is very easy process to remove elements from Linked list. You have to just take index number and then use this index to remove that element. I have written following example to do that. Just go through it.

package org.kodejava.example.util;

import java.util.LinkedList;

public class LinkedListRemove {
    public static void main(String[] args) {
        LinkedList<String> names1 = new LinkedList<String>();
        names1.add("komal");
        names1.add("ran");
        names1.add("koral");
        names1.add("limaye");

        System.out.println("Original values are:");
        System.out.println("====================");
        for (String name : name1) {
            System.out.println("Name = " + name1);
        }

        
        namess.remove(2);
        
        System.out.println("New values are:");
        System.out.println("====================");
        for (String name : names1) {
            System.out.println("Name = " + name1);
        }
    }
}

It is very e4asy process to remove an item from LinkedList in java program. Just use following code in your java program and then try to run it in your computer. Just pass any value you want to remove from Linked list.

   
      public boolean removeSpecific(Item things)

      {
  
      if(heads != null)
   
      {
  
      if(previouss == null)
 
      heads = heads.next;
 
      else if(current.data.equals(things))

      {
 
      previouss.next = currentss.next;

      currents = currents.next;

      counts--;

      return true;

      }

      }

      return false;

      }

Just try to understand following program. I have written that program for you. It is very easy process to remove any specific item from linked list. Just insert index number of that particular elements and then it automatically remove from linked list.

 
      public void addNode(int coeffs, int powers)
 
      {

      if (heads == null)
  
      {
 
      heads = new Node(coeffs, powers, null);
  
      degrees = powers;
  
      }

      else

      {
  
      Node p = heads;

      Node lasts = null;

       

      while (p != null)

      {

 
      {

      if (lasts == null)

      heads = new Node(coeffs, powers, p);

      else
 
      lasts.next = new Node(coeffs, powers, p);
  
      degrees = powers;

      break;

      }
  
      last = p;

      p = p.next;

      }
 
      if (p == null) 
      {

      lasst.next = new Node(coeffs, powers, null);

      }
 
      }
 
      }

You have to define one class which must have delete() method, which will delete all nodes equal() to Node n and delete() method should return true if at least one node could be removed, and return false otherwise. You have to use Use Java syntax. class. You have to use index number to delete specific element from Linked list.
