invalid method declaration; return type required

Im pretty new to Java (Taking my first class, AP Computer Science no less)
The assignment is to write a graphical program that features the property of inheritance and uses constructors.
Im drawing a creeper from minecraft, ive been tryin to troubleshoot it but im stumped :@:
help please?

Code:

import java.awt.*;
import java.applet.*;
public class lab09 extends Applet
{
        public void paint(Graphics g)
        {
                MinecraftCreeper jack = new MinecraftCreeper(g);

        }
}

class MinecraftCreeper extends Creeper
{

        public MinecraftCreeper(Graphics g)

        {
                super(g);
        }
}
class Creeper
{
        public Creeper(Graphics g)
        {
                g.setColor(new Color(136,192,109));
                g.fillRect(400,60,100,100);
                g.setColor(new Color(0,0,0));
                g.fillRect(420,80,20,20);
                g.fillRect(460,80,20,20);
                g.fillRect(440,100,20,30);
                g.fillRect(430,110,10,30);
                g.fillRect(460,110,10,30);
        }
}
class CreeperTorso extends Torso
{
        public Torso(Graphics g)
        {
                g.setColor(new Color(0,0,0));
                g.fillRect(40,80,20,20);
        }
}

Can you show the error message you ends up with?

Inside the CreeperTorso class how can you define this?

Code:

---

public Torso(Graphics g)
    {
        g.setColor(new Color(0,0,0));
        g.fillRect(40,80,20,20);
    }

---

Do you know really what it is?

Code:

---

class CreeperTorso extends Torso {
    public Torso(Graphics g)

---

Hmmm!

What is extend does and how the constructor use. ;) Let see OP could find that.

OK i cant believe i missed that....thanks for pointing it out guys! i have it now

You are welcome.

BTW, are you working on with an IDE?

yeah Im using JCreator

I haven't use JCreator. But most of the time IDE give a lots of hints. I just compiled your code in NetBeans, and it give the following.

error: invalid method declaration; return type required
public Torso(Graphics g)
1 error

So looking at the pointed line of code, I can get some sense about the error. :) I believe that JCreator does the same.

Yeah, it does, I dont know i just blanked out I guess when I was trying to figure out what was wrong. Haha, like I said though im a total newbie at this.

Of course. With the practice you'll be able to catch those things. :) Same here when I start to coding.

May be that is one of the advantages that stick into one or two IDEs. Then you know from A-Z. Anyway, good luck with Java.
