编写小应用程序(Applet)求10的阶乘，即10！
用Applet运行即可。

Answer 1

import java.applet.*;import java.awt.*;

public class Example3_7 extends Applet

{

public void paint(Graphics g)

{

long jiecheng=1;

for(int i=10;i>=1;i--)

{ jiecheng=jiecheng*i; }

g.drawString("10的阶乘是"+jiecheng,10,20);

}

}

Answer 2

public class Jiecheng {

public static void main(String[] args) {
int a=1;
for(int i=1;i<=10;i++){
a = a*(i+1) ;
}
System.out.println(a);

}

}

Answer 3

import java.applet.Applet;
import java.awt.Graphics;

public class Tapplet extends Applet {
public void paint(Graphics g)
{
long j=1;
for (int i=1;i<=10;++i) j*=i;
g.drawString(Long.toString(j), 50, 50);
}
}
