A. 如何用java在页面上用循环打印一个爱心形状
import java.util.Scanner;
public class test{
static void draw(int n)
{
int i,j;
for (i=1-(n>>1);i<=n;i++)
if (i>知仿拿0)
{
for (j=0;j<i;j++) System.out.print("大瞎 ");
for (j=1;j<=2*(n-i)+1;j++)
if (j==1||j==2*(n-i)+1) System.out.print(" *");
else System.out.print(" ");
System.out.println("\n");
}
else
if (i==0)
{
System.out.print(" *");
for (j=1;j<n;j++) System.out.print(" ");
System.out.print(" *");
for (j=1;j<n;j++) System.out.print(" ");
System.out.print(" *\n");
}
else
{
for (j=i;j<0;j++) System.out.print(" ");
for (j=1;j<=n+2*i+1;j++)
if (i==1-(n>>1)) System.out.print(" *"搭搭);
else if (j==1||j==n+2*i+1) System.out.print(" *");
else System.out.print(" ");
for (j=1;j<=-1-2*i;j++) System.out.print(" ");
for (j=1;j<=n+2*i+1;j++)
if (i==1-(n>>1)) System.out.print(" *");
else if (j==1||j==n+2*i+1) System.out.print(" *");
else System.out.print(" ");
System.out.print("\n");
}
}
public static void main(String[] args) {
System.out.println("Please input the size (n>=4):");
Scanner sc = new Scanner(System.in);
int n = sc.nextInt();
draw(n);
}
}先说明这个不是我写的 是看了有人用C语言写的 就顺便改成了java 结果有点像爱心 还凑合着 你看看怎么样吧 哈
