用js怎么实现菱形（用js怎么实现菱形图像）

用java编写菱形

for(i=1;i=4;i++)

{

这个小的for用js怎么实现菱是打印每一行前边的空格

for(j=1;j=4-i;j++)

System.out.print(" 用js怎么实现菱");

这个是打印星星的

for(j=1;j=2i-1;j++)

System.out.print(""碧数);

这个是打印完一行的换行

System.out.println("");

}

下边的是一样的  只不过每一行的空格悔纤首和星星数   和上边竖则是用js怎么实现菱翻过来的

for(i=1;i=3;i++)

{

for(j=1;j=i;j++)

System.out.print(" ");

for(j=1;j=7-2i;j++)

System.out.print("");

S用js怎么实现菱ystem.out.println("");

}

【Java输出菱形】用for循环，并且调用Java方法输出七行的菱形 ，要求见下,大侠们帮帮忙！

public class Draw{

public static void main(String[] args)//

{

int n=4;

/携颂册/前4行.上半部分

for(int i=1;i=n;i++)//控制行数

{

for(int k=n-1;k=i;k--)//打印空格

{

System.out.print(" ");

}

for(int j=1;j=2i-1;j++)//打印

{

System.out.print("");

}

System.out.println();

}

//辩宏后3行,下半部分

for(int i=n-1;i=1;i--)

{

for(int k=i;k=n-1;k++)

{

System.out.print(" ");

}

for(int j=1;j=2i-1;j++)

{

System.out.print("");

}

System.out.println();

}

}

}

如何从页面上输入数字来打印菱形 js

外层for是循环行

内层的两个for是输出每行的空格和

你出示的这句恰恰体现谨拦祥了用户输入衡肢的数字和行之间的关系。

自祥搏己写着简单，读别人的就不简单了。因为他没有注释。不扣它也罢。

怎么用for循环实现菱形？

用for循环实现的菱形谨磨图形老老的Java程序如下：

public class Test {

public static void main(String[] args) {

final int N=4;

for (int i = 1; i = N2-1; i++) {

for (int j = 1; j = Math.abs(N - i); j++) {

System.out.print(" ");

}

for (int k = 1; k = 2N-1-Math.abs(i-N)2; k++) {

System.out.print(""祥含斗);

}

System.out.println();

}

}

}
