问题描述
我正在尝试使用for循环和嵌套for循环来制作圣诞树。对我来说,我需要能够用*来制作金字塔。我已经尝试了无数次,并且遇到了问题。这里是我的代码: $ b $ pre $ for(int i = 1; i <= 10; i ++){ for int j = 10; j> i; j - ){ System.out.println(); (int k = 1; k< = i; k ++){ System.out.print(*); (int h = 1; h <= 10; h ++){$ b $() (int l = 10; l
我试图做的是:
* *** ***** *******解决方案
试试这个简单的代码:
public class ChristmasTree { public static void main(String [] args){ for(int i = 0 ; i <10; i ++){ for(int j = 0; j <10 -i; j ++) System.out.print(); for(int k = 0; k <(2 * i + 1); k ++) System.out.print(*); System.out.println(); $ b $ p它使用3个循环:
I am trying to make a christmas tree using for loops and nested for loops. For me to do that I need to be able to make a pyramids with *. I have tried countless times and I am having problems making one. Here is my code:
for(int i=1;i<=10;i++){ for(int j=10;j>i;j--){ System.out.println(" "); } for(int k=1;k<=i;k++){ System.out.print("*"); } for(int l=10;l<=1;l++){ for(int h=1;h<=10;h++){ System.out.print(" "); } } System.out.println(); }What I am trying to do is:
* *** ***** *******解决方案
Try this much simpler code:
public class ChristmasTree { public static void main(String[] args) { for (int i = 0; i < 10; i++) { for (int j = 0; j < 10 - i; j++) System.out.print(" "); for (int k = 0; k < (2 * i + 1); k++) System.out.print("*"); System.out.println(); } } }It uses 3 loops:
- first one for the number of rows,
- second one for printing the spaces,
- third one for printing the asterisks.
