古希腊悲剧喜剧集:谁来帮我看一下这个Java applet程序那里出错了

编译是通过了 但就是显示的都重在一起了啊

import java.applet.Applet;
import java.awt.*;
public class showresults extends Applet
{
Label prompt;
TextField input1,input2;
float addition=0,
subtraction=0,
multiplication=0,
division=0,
average=0,max=0;

public void init()
{
prompt=new Label("Enter the int and float:");
input1=new TextField(3);
input2=new TextField(3);
add(prompt);
add(input1);
add(input2);
}
public void paint(Graphics g)
{
g.drawString("x+y="+addition,50,80);
g.drawString("x-y="+subtraction,50,80);
g.drawString("x*y="+multiplication,50,80);
g.drawString("x/y="+division,50,80);

}
public boolean action(Event e,Object o)
{

}
return true;
