    Default Creating random objects

    Hey everyone. So in my Javascript class we have to do create a program that runs a program created by one of our classmates that displays certain objects. This is what I'm working with:


    /*
    Ryan Coote
    4/11/10
    Man
    */

    import java.util.Random;
    import java.awt.*;

    public class Man
    {
    private int diameter, x, y;
    private Color hue;
    public boolean doubled;

    // Constructor
    public Man (int size, Color shade, int upperX, int upperY, boolean goodTruth)
    {
    diameter = size;
    hue = shade;
    x = upperX;
    y = upperY;
    doubled = goodTruth;
    }

    public Man (int upperX, int upperY)
    {
    Random generator = new Random();

    diameter = generator.nextInt(50);
    hue = new Color (generator.nextInt(255), generator.nextInt(255), generator.nextInt(255));
    x = upperX;
    y = upperY;
    if (generator.nextInt(2) == 1)
    {
    doubled = true;
    }
    else
    {
    doubled = false;
    }
    }

    public void draw (Graphics page)
    {
    page.setColor(hue);
    page.drawOval(x+(int)((diameter/2)*0.14), y, (int)(diameter*0.14), (int)(diameter*0.14));//The Head
    page.drawLine(x+((int)(diameter/2)), y+((int)(diameter* 0.14)), x+((int)(diameter/2)), y+((int)(diameter*0.7)));//The Body
    page.drawLine(x, y+((int)(diameter/2)), x+((int)(diameter/2)), y+((int)(diameter/0.25)));//left arm
    page.drawLine(x+diameter, y+((int)(diameter/0.25)), x+((int)(diameter/2)), y+((int)(diameter/2)));//right arm
    page.drawLine(x, y+diameter, x+((int)(diameter/2)),y+((int)(diameter*0.7)));//left leg
    page.drawLine(x+((int)(diameter/2)),y+((int)(diameter*0.7)),x+diameter, y+diameter);//right leg
    page.drawRect(x, y, diameter, diameter);// Square of Preportion

    if(doubled == true)
    {
    page.drawString("Oops, looks like I didn't finish it.", x, y+diameter+10);
    }

    }

    public void setDiameter (int size)
    {
    diameter = size;
    }

    public void setColor (Color shade)
    {
    hue = shade;
    }

    public void setX (int upperX)
    {
    x = upperX;
    }

    public void setY (int upperY)
    {
    y = upperY;
    }

    public int getDiameter ()
    {
    return diameter;
    }

    public Color getColor ()
    {
    return hue;
    }

    public int getX ()
    {
    return x;
    }

    public int getY ()
    {
    return y;
    }
    }


    So I need to use a for loop in my driver so that it draws them in random spots. The program above is set up properly, I just need some help with my driver. I don't get how to use the loop. I already have the shell for my driver:

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

    public class SplatPanel extends JPanel
    {
    private Man Object;

    //-----------------------------------------------------------------
    // Constructor: Creates five Pumpkin objects.
    //-----------------------------------------------------------------
    public SplatPanel()
    {
    Object = new Man(size, hue, x, y, doubled);

    setPreferredSize (new Dimension(300, 200));
    setBackground (Color.black);
    }

    public void paintComponent (Graphics page)
    {
    super.paintComponent(page);

    for (int x = 0;x<10;x++)
    {
    Object.draw(page);
    }
    }
    }

    obviously that doesn't work, I just have no idea how exactly to write the for loop. Again, I need to create 10 random objects. Thanks!

    Did you google?
    for loop is similar in java and javascript.
