在Java中打印出ASCII星号 [英] Print out an ASCII star in java

问题描述

我正在尝试使用 for 循环将下面的图像打印出来.我正在使用 for 循环和 if 语句在Java中创建ASCII星号.

I am trying to print out the image below using a for loop. I'm using for loops and if statements to create an ASCII star in Java.

我的代码:

public class asciistar {
    public static void main(String[] args) {
        final int X = 9;
        for (int R = 0; R < X; R++) {
            for (int V = 0; V < X; V++) {
                if (R == V || R + V == X - 1 || V == X / 2 || R == X / 2) {
                    System.out.print("* ");
                } else {
                    System.out.print("  ");
                }
            }
        }
    }
}

推荐答案

您的代码有效！只需在外部循环的末尾添加换行符的打印即可:

Your code works! Just add the printing of a newline at the end of the outer loop:

public static void main(String[] args) {
    final int X = 9;
    for (int R = 0; R < X; R++) {
        for (int V = 0; V < X; V++) {
            if (R == V || R + V == X - 1 || V == X / 2 || R == X / 2) {
                System.out.print("* ");
            } else {
                System.out.print("  ");
            }
        }
        System.out.println("");
    }
}

结果:

*       *       * 
  *     *     *   
    *   *   *     
      * * *       
* * * * * * * * * 
      * * *       
    *   *   *     
  *     *     *   
*       *       *
