- Java code
public static void main(final String[] args) { final String[] weekdays ={"MON", "TUE", "WED", "THU", "FRI", "SAT", "SUN"}; Scanner scanner = new Scanner(System.in); while (true) { System.out.print("请输入数字1-7（输入0结束）："); int x = scanner.nextInt(); if (x == 0) break; if (x > 7 || x < 0) continue; System.out.printf("今天是 %s%n", weekdays[x-1]); } }
