"第" + i + "排，第 " + j + "列可售"

我觉得，第三段练习，是要加强的
public class SellSeats {
public static void main(String[] args) {
System.out.println("剧院可售座位信息：");
for (int i = 1; i <= 4; i++) {
for (int j = 1; j <= 10; j++) {
if (j == 1 || j == 10) {
continue;
} else {
System.out.println("第" + i + "排，第 " + j + "列可售");
}
}
}
}
}
