import java.util.Scanner;

public class ppp {
public static void main(String[] args) {

    // 固定的获得Scanner工具的写法
    // 类型名称 变量名 = 值;
    Scanner ipt = new Scanner(System.in);

    // 使用工具的功能,得到一个整数
    System.out.println("请输入内容：");
    int a = ipt.nextInt();
    System.out.println("从键盘接收到了一个整数，值为" + a);

    for (int i = 0; i < a; i++) {
        System.out.print("*");

    // 代码简化，输出矩形
    int num = 4;


    for (int j = 0; j < num; j++) {
        // 输出一行星花，由三个符号组号
        for (int i = 0; i < num; i++) {
            System.out.print("*");
        }
        System.out.println();

    }
