So, I'm very new at JAVA. I'm creating a bow and arrow game. I've drawn everything out, but I don't understand how to have the arrow hit the moving target and stay there.

Here's my code:
-------------
GameFrame class:

import javax.swing.*;
import java.awt.*;
import java.awt.event.*;

public class GameFrame extends JPanel implements ActionListener
{
	static JButton shoot;
	Graphics g2d;
	JPanel cards;
	 
    	 
	public GameFrame()
	{
    	setFocusable(true);
	}
    
	public void paint(Graphics g)
	{
    	super.paint(g);
    	g2d = (Graphics)g;   	 
	}

	public void actionPerformed(ActionEvent a)
	{
   	 
	/*if(a.getActionCommand().equals("Go to Level 1")){
   		 CardLayout cl=(CardLayout)(cards.getLayout());
   		 cl.show(cards, "l1");
   	 }
   	 else if(a.getActionCommand().equals("Go to Level 2")){
   		 CardLayout cl=(CardLayout)(cards.getLayout());
   		 cl.show(cards, "l2");
   	 }
   	 else if(a.getActionCommand().equals("Go to Level 3")){
   		 CardLayout cl=(CardLayout)(cards.getLayout());
   		 cl.show(cards, "l3");
   	 }
   	 else if(a.getActionCommand().equals("Go to Menu")){
   		 CardLayout cl=(CardLayout)(cards.getLayout());
   		 cl.show(cards, "m1");
   	 }
   	 else
   		 System.exit(0);*/
	}
    
	public void setUp()
	{
    	JFrame frame = new JFrame("Bull's Eye");
    	JPanel panel = new Level1();
   	 
    	JPanel menu=new JPanel();
    	/*JPanel level1=new JPanel();
    	JPanel level2=new JPanel();
    	JPanel level3=new JPanel();
    	JMenuBar menubar=new JMenuBar();
    	JMenu file=new JMenu("Levels");
   	 
    	JMenuItem eMenuItem4=new JMenuItem("Go to Menu");
    	JMenuItem eMenuItem= new JMenuItem("Go to Level 1");
    	JMenuItem eMenuItem2=new JMenuItem("Go to Level 2");
    	JMenuItem eMenuItem3=new JMenuItem("Go to Level 3");
    	JMenuItem eMenuItem5=new JMenuItem("Exit");
   	 
    	eMenuItem.addActionListener(this);
    	eMenuItem2.addActionListener(this);
    	eMenuItem3.addActionListener(this);
    	eMenuItem4.addActionListener(this);
   	 
    	file.add(eMenuItem);
    	file.add(eMenuItem2);
    	file.add(eMenuItem3);
    	file.add(eMenuItem4);
    	file.add(eMenuItem5);
   	 
    	menubar.add(file);
   	 
    	frame.setJMenuBar(menubar);
   	 
    	cards=new JPanel(new CardLayout());
   	 
    	cards.add(menu,"m");
    	cards.add(level1,"l1");
    	cards.add(level2,"l2");
    	cards.add(level3,"l3");
   	 
    	frame.add(cards, BorderLayout.CENTER);*/
   	 
    	frame.setSize(1000, 800);

    	shoot = new JButton("Click to shoot!");
    	panel.add(shoot);
    	shoot.addActionListener(new Level1());
    	shoot.addKeyListener(new Level1());

    	frame.add(panel);   	 

    	frame.setTitle("Bull's Eye!");
    	frame.setLocationRelativeTo(null);
    	frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
    	frame.setVisible(true);	}
    
	public static void main(String[]args)
	{
    	GameFrame gf = new GameFrame();
    	gf.setUp();
	}
}

Level1 class (where I draw the stuff)

import javax.swing.*;
import java.awt.*;
import java.awt.event.*;

public class Level1 extends JPanel implements ActionListener, KeyListener
{
    	Image background;
	Image target;
	Image Player_char;
	Image arrow;    
	static int x = 530, velx = 1, arrowY = 230;
	static int y = 170, vely = 1;
	//Find a way for the arrow to seamlessly shoot out!

	Timer mainTimer = new Timer(10, this);

	public  Level1()
	{
    	ImageIcon ic = new ImageIcon("src/background.jpg");
    	background = ic.getImage();

    	ImageIcon ic3 =new ImageIcon("src/target.png");
    	target=ic3.getImage();

    	ImageIcon ic2 = new ImageIcon("src/character.png");
    	Player_char = ic2.getImage();

    	ImageIcon ic4 = new ImageIcon("src/arrow.png");
    	arrow = ic4.getImage();    
	}
	
	public void keyPressed(KeyEvent k) 
	{
		int key = k.getKeyCode();
		
		if (key == KeyEvent.VK_UP)
		{
			arrowY = 130;
			x = 530;
		}
		
		else if (key == KeyEvent.VK_DOWN)
		{
			arrowY = 330;
			x = 530;
		}			
	}	
	public void keyReleased(KeyEvent arg0) {}
	public void keyTyped(KeyEvent arg0) {}

	public void paintComponent(Graphics g2d)
	{
   	 
    	g2d.drawImage(background, 0, 0, null);
    	g2d.drawImage(target, 4, y, null);
    	g2d.drawImage(Player_char, 700, 140, null);
    	g2d.drawImage(arrow, x, arrowY, null);
    	mainTimer.start();
	}
	
	public void checkCollisions()
	{
		//Rectangle r1 = ((Shape) arrow).getBounds();
		//Rectangle r2 = ((Shape) target).getBounds();

		//if (r1.intersects(r2))
		//{
		//	
		//}

               //What do I do here?
		
	}
	
	public void actionPerformed(ActionEvent a) //Add the change of positioning of arrow!
	{
    	if (a.getSource() == GameFrame.shoot)
    	{
   		 arrow l1=new arrow();
   		 l1.getx();
    	}
    	repaint();
   	 
    	if (y < 0 || y > 500) //Add a moving obstacle! And animate it like this...
        	vely = -vely;
    	y = y - vely;   	 
    	repaint();
	}
}

Arrow class

import javax.swing.*;
import java.awt.*;
import java.awt.event.*;

public class arrow implements ActionListener
{

	Timer timer = new Timer(5, this);

	public arrow()
	{
		timer.start();   	 
	}

	public void actionPerformed(ActionEvent e)
	{
		if (Level1.x <= 0 || Level1.x >= 1000)
			Level1.velx = Level1.velx;
		Level1.x = Level1.x - Level1.velx;
	}
	
	public int  getx (){
		int x=Level1.x;
		return(x);
	}

}
