Java经典编程题50道之四十七
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*。
public class Example47 {
public static void main(String[] args) {
int[] a = { 10, 7, 6, 15, 4, 3, 20 };
display(a);
}
public static void display(int[] a) {
System.out.print("读取的整数有:");
for (int r : a) {
System.out.println(r + " ");
}
for (int i = 0; i < a.length; i++) {
System.out.print("打印" + a[i] + "个*:");
for (int j = 0; j <= a[i]; j++) {
System.out.print("*");
}
System.out.println();
}
}
}
