Question

我正在尝试使用充满星号的数组制作图片。问题是，我不知道如何使星号出现在某些坐标中。如果你能提供帮助那就太棒了。

public class Array {

    public static void main (String[] args) {
        horizontalLine();
    }

    public static void horizontalLine () {

        String [][] anArray;
        anArray = new String [2][8];

        for (int i = 0; i < 2; i ++) {

            for (int j = 2; j < 8; j ++) {
                System.out.print ("*");
                anArray [i][j] = "";
            }
        }
    }
    public static void picture () {
        horizontalLine();
    }
}

您只需将符号放在anArray [i][j] = "*";内的所需位置即可。使用spaces anArray [i][j] = " ";（或其他符号）填充铰孔位置。填充anArray后，只需将其打印出来即可。例如：

String [][] anArray = new String [N][M];

for ( i = 0; i < N; i ++)
  for ( j = 0; j < M; j ++)
  {
    if(i == 0 || i == N-1 || j == 0 || j == M-1) anArray[i][j] = "*"; // Put * on the frame
    else anArray[i][j] = " "; // Put spaces inside

   }

 for ( i = 0; i < N; i ++)  //Print the picture
   for ( j = 0; j < M; j ++)
   {
       printf("%s",anArray[i][j]);
       if(j == M-1) printf("\n");
   }
