在eclipse上运行时为什么显示没有初始化？
import java.applet.*;import java.awt.*;
public class ex10_8 extends Applet{
int rows;
public static long fac(int n){
long res=1;
for(int k=2;k<=n;k++)
res=res*k;
return res;
}
public static long com(int n,int m){
return fac(n)/(fac(n-m)*fac(m));
}
public void init(){
rows=Integer.parseInt(getParameter("lines"));
}
public void paint(Graphics g){
int x,y=10;
for(int n=10;n<=rows;n++){
x=10;
for(int m=0;m<=n;m++){
g.drawString(""+com(n,m), x, y);
x=x+40;
}
y=y+20;}}}
