Hello I have a game where you drag bits of food around the screen. I want to be able to click on an ingredient and drag it to another part of the screen where I release the mouse. I am new to java so I do not really know how to do this please help me Here is me code. This is the class with the mouse listeners in it:

   public void mousePressed(MouseEvent e) {
    if (e.getButton() == MouseEvent.BUTTON1) {
        Comp.ml = true;
        // placing
        if (manager.title == true) {
            if (title.r.contains(Comp.mx, Comp.my)) {
                title.overview = true;

            } else if (title.r1.contains(Comp.mx, Comp.my)) {
                title.options = true;

            } else if (title.r2.contains(Comp.mx, Comp.my)) {
                System.exit(0);
            }
        }
        if (manager.option == true) {
            optionsMouse(e);
        }

        mouseinventory(e);
    } else if (e.getButton() == MouseEvent.BUTTON3) {
        Comp.mr = true;
    }

}

private void mouseinventory(MouseEvent e) {
    if (e.getButton() == MouseEvent.BUTTON1) {

    } else if (e.getButton() == MouseEvent.BUTTON1) {

    }
}

@Override
public void mouseReleased(MouseEvent e) {
    if (e.getButton() == MouseEvent.BUTTON1) {
        Comp.ml = false;

    } else if (e.getButton() == MouseEvent.BUTTON3) {
        Comp.mr = false;

    }

}

@Override
public void mouseDragged(MouseEvent e) {
    for(int i = 0; i < overview.im.ing.toArray().length; i ++){
        if(overview.im.ing.get(i).r.contains(Comp.mx,Comp.my)){
                overview.im.ing.get(i).newx = Comp.mx;
                overview.im.ing.get(i).newy = Comp.my;

                overview.im.ing.get(i).dragged = true;


        }else{
            overview.im.ing.get(i).dragged = false;
        }
    }
}

@Override
public void mouseMoved(MouseEvent e) {
    Comp.mx = e.getX();
    Comp.my = e.getY();
    // System.out.println("" + Comp.my);
}

This is the class called ingredient

    public abstract class Ingrediant {

public int x,y,id,lastx,lasty,newx,newy;
public boolean removed = false,dragged = false;
public int width;
public int height;

public Rectangle r = new Rectangle(x,y,width,height);

public Ingrediant(){
    r = new Rectangle(x,y,width,height);
}

public abstract void tick();

public abstract void render(Graphics g);

}

and this is a class which extends ingredient called hagleave

  public class HagLeave extends Ingrediant {

private Image img;

public HagLeave(int x, int y, int id) {
    this.x = x;
    this.y = y;
    this.newx = x;
    this.newy = y;
    this.id = id;
    width = 75;
    height = 75;

    r = new Rectangle(x,y,width,height);

}

public void tick() {
    r = new Rectangle(x,y,width,height);

    if(!dragged){
        x = newx;
        y = newy;
    }
}

public void render(Graphics g) {
    ImageIcon i2 = new ImageIcon("res/ingrediants/hagleave.png");
    img = i2.getImage();
    g.drawImage(img, x, y, null);

    g.setColor(Color.red);
    g.drawRect(r.x, r.y, r.width, r.height);

}

}

The arraylist is in a class called ingrediantManager:

    public class IngrediantsManager {

public ArrayList<Ingrediant> ing = new ArrayList<Ingrediant>();

public IngrediantsManager(){
    ing.add(new HagLeave(100,200,1));
    ing.add(new PigHair(70,300,2));
    ing.add(new GiantsToe(100,400,3));

}
public void tick(){
    for(int i = 0; i < ing.toArray().length; i ++){
        ing.get(i).tick();
        if(ing.get(i).removed){
            ing.remove(i);
            i--;
        }
    }
}

public void render(Graphics g){
    for(int i = 0; i < ing.toArray().length; i ++){
        ing.get(i).render(g);
    }
}

}
