java in ImageIO usage and display pictures

in jar package I used to write a java program can run normally , but the picture after the program generates jar packets are not displayed. After using the Internet to find ImageIO to load pictures, but the program has been commissioning wrong, seeking guidance about the great God to help . Below is a picture of that part of the code . Error shows Type mismatch: cannot convert from BufferedImage to ImageIcon.

JLabel labellogo = new JLabel();
  ImageIcon imagelogo = new ImageIcon();	
  				
  try {
  					 
  		imagelogo=ImageIO.read(getClass().getClassLoader().getResource("./images/Logo.jpg"));
  		
  	} catch (Exception e) {
  					  // TODO Auto-generated catch block
  				 e.printStackTrace();
  					      }
  
  				 labellogo.setIcon(imagelogo);
                   dialogPanel.add(labellogo,BorderLayout.EAST);

------ Solution ------------------------------------- -------

ImageIcon imagelogo = new ImageIcon();

change to

BufferedImage imagelogo = null;

------ Solution ------------------------------------- -------
Do naughty , quick problem solving            Upstairs is a positive solution        but it does not appear to run the entire form  

  package test;
  import java.awt.BorderLayout;
  import java.awt.Image;
  import java.awt.Toolkit;
  import java.io.ByteArrayOutputStream;
  import java.io.IOException;
  import java.io.InputStream;
  import java.net.URL;
  
  import javax.swing.ImageIcon;
  import javax.swing.JFrame;
  import javax.swing.JLabel;
  
  public class Test {
  	public Test() {
  		JFrame frame = new JFrame();
  		JLabel labellogo = new JLabel();
  		URL url = Test.class.getResource("images/1.PNG");;
  		System.out.println(url);
  		ImageIcon icon = new ImageIcon(url);
  		System.out.println(icon);
  		labellogo.setIcon(icon);
  		frame.add(labellogo, BorderLayout.EAST);
  		frame.setSize(300, 300);
  		frame.setVisible(true);
  	}
  
  	public static void main(String[] args) {
  		Test t = new Test();
  	}
  }
