   }

    void delet(int index) {
         for (Video v:videos)
        {

            {

    public Video (String title, String genre,String id)
    {
        this.title = title;
        this.genre = genre;
        this.id = id;
    }

   

    
    

    public String getGenre() {
        return genre;
    }

    public void setGenre(String genre) {
        this.genre = genre;
    }

    public String getTitle() {
        return title;
    }

    public void setTitle(String title) {
        this.title = title;
    }
    public void removAll()
    {
        
    }
@Override public String toString()
 {
  String mystring = title+ genre + id  ; 
  return mystring;
 }








private void jButton1ActionPerformed(java.awt.event.ActionEvent evt) {                                         

   //int index = Integer.parseInt(jTextField1.getText());
    dao.create(jTextField1.getText(), jTextField2.getText(), jTextField3.getText());
    Video[]filmer=dao.getAllVideos();
    jTextArea1.setText(null);
    jTextArea1.append(""+filmer.length+"\n");
    for (Video v:filmer)
    {
        jTextArea1.append(v.title+";"+v.genre+v.id+"\n");
    }

The question here : under JButton1 I can add. but under jButton2 for remove I cant remove. And if you can help also under jButton3 for serach and under juButton 4 for update and juBtton 5 for size.
Note: I used ready Swing pallete.

Thank you again!.
Abdalla1.

please next time don'tt write the question inside the code tags.
As for the problem, what do you mean by 'can't remove'?
do you get any error messages? if yes post them.
Also, where is the code for the remove\add\ methods for buttons1 and 2?

import java.util.*;

public class Remove {
    int x;
    
    Remove(int x) {

    }
    public String toString() {

    public static void main(String[] args) {
    	ArrayList<Remove> al = new ArrayList<Remove>();
    	for(int i = 0; i <= 5; ++i)
    		al.add(new Remove(i));
    	
    	// you can't remove from an Iterator while it is in progress
    	// it will egenerate a ConcurrentModificationException
    	for(Remove r : al) {
 //   		if(r.x == 3)
 //   			al.remove(r);   <--- won't work
    	}
    	
    	// you\ll have to use the old way
    	for(int i = 0; i < al.size(); ++i) {
    		if(al.get(i).x == 3)
    			al.remove(i);
    	}
    	for(Remove r : al)
    		System.out.println(r);
    	
    	
    }
}




       	// and actuially if you have more than one to remove better to do it in reverse order
    	for(int i = al.size() - 1; i >= 0; --i) {
    		if(al.get(i).x == 3)
    			al.remove(i);
    		if(al.get(i).x == 4)
    			al.remove(i);
    	}

OK good but as i told you I have jTextField1,jTextField2,jTExtField3, and the jButtons and jTextArea1. and the juBtton remove or search it should be like this but in right way? I need the right code include the jTextFields.as the folowing:

private void jButton1ActionPerformed(java.awt.event.ActionEvent evt) { 

// this code for add, but I want another for remvo or delet or serach in the same way                                        

   //int index = Integer.parseInt(jTextField1.getText());
    dao.create(jTextField1.getText(), jTextField2.getText(), jTextField3.getText());
   
    Video[]filmer=dao.getAllVideon();
   jTextArea1.setText(null);
    jTextArea1.append(""+filmer.length+"\n");
    for (Video v:filmer)
    {
        jTextArea1.append(v.title+";"+v.genre+v.id+"\n");
    }

AND WHAT IS THE PROBLEM WITH IT ? I HAVE ALREADY REPLIED TO THAT IN ONE OF YOUR MULTIPLE POSTS/THREADS
