题目:读取7个数(1—50)的整数值,每读取一个值,程序打印出该值个数的*。 

 1    public class _047ReadNumberPrintStar {
 2 
 3     public static void main(String[] args) {
 4         readNumberPrintStar();
 5     }
 6 
 7     private static void readNumberPrintStar() {
 8         Scanner s = new Scanner(System.in);
 9         int n = 1, num;
10         while (n <= 7) {
11             do {
12                 System.out.println("请输入一个1--50之间的整数:");
13                 num = s.nextInt();
14             } while (num < 1 || num > 50);
15             for (int i = 1; i <= num; i++) {
16                 System.out.print("*");
17             }
18             System.out.println();
19             n++;
20         }
