java Applet paint 中如何调用其他函数绘图

为什么这样会不出来draw()中的内容啊。。
=======================================
import java.applet.*;
import java.awt.*;

public class QuestionAppletDemo extends Applet{
public void init()
{
s = new String("Hello World!");
}
public void draw()
{
Graphics gLine= null;
gLine.drawString("abcde", 50, 50);
}
public void paint(Graphics g)
{
g.drawString(s,25,25);
g.setColor(Color.RED);
draw();
}
}

Answer 1

public void draw(Graphics g)
{
g.drawString("abcde", 50, 50);
}
public void paint(Graphics g)
{
g.drawString(s,25,25);
g.setColor(Color.RED);
draw(g);
}

请改成这样

Answer 2

public void draw(Graphics g)
{
g.drawString("abcde", 50, 50);
}
public void paint(Graphics g)
{
g.drawString(s,25,25);
g.setColor(Color.RED);
draw(g);
}
