class Syouchiku
{
protected int num;
public Syouchiku()
{
num=0;
}
public void setsyouchiku()
{
for(int i=-8; i<=8; i++){
setsyouchiku2(i*i);
}
}
public void setsyouchiku2(int x)
{
for(int j=0; j<x; j++){
System.out.print("*");
}
System.out.println("");
}
}

public class Qs19
{
public static void main(String args[])
{
Syouchiku syo = new Syouchiku();
syo.setsyouchiku();
}
}
ちなみに答え。面白いｗ
