一桁の整数を入力すると、n×nの乗算表を表示　for文を使用

public class ren06_9
{
public static void main (String[] args) throws IOException
{
BufferedReader br =
new BufferedReader( new InputStreamReader(System.in));
System.out.print("整数を入力 > ");
int n = Integer.parseInt( br.readLine() );
System.out.print(" ");
System.out.print(" |");
for(int i=1; i<=n; i++){
System.out.printf("%4d",i);
}
System.out.println();
System.out.print("----");
for(int i=1; i<=n; i++){

System.out.print("----");
}
System.out.println();
for(int i=1; i<=n; i++){
System.out.printf("%3d",i);
System.out.print("|");
for(int j=1; j<=n; j++){
System.out.printf("%4d",i*j);
}
System.out.println();
}
}
}
