Java 打印字母 M 图案的程序

在这个 Java 图案程序中,我们展示了如何使用 for 循环、while 循环和函数来打印字母 M 形状或图案的星号。

import java.util.Scanner;

public class Example
{
private static Scanner sc;

public static void main(String[] args)
{
sc = new Scanner(System.in);

System.out.print("Enter Rows = ");
int rows = sc.nextInt();

for (int i = 0; i < rows; i++)
{
System.out.printf("*");

for (int j = 0; j <= rows; j++)
{
if ((j == rows) || (j == i && j < rows / 2)
|| (j == rows - i - 1 && j > rows / 2))
{
System.out.printf("*");
}
else
{
System.out.printf(" ");
}
}
System.out.println();
}
}
}
Enter Rows = 17
**               **
* *             * *
*  *           *  *
*   *         *   *
*    *       *    *
*     *     *     *
*      *   *      *
*       * *       *
*                 *
*                 *
*                 *
*                 *
*                 *
*                 *
*                 *
*                 *

在此字母 M 形状或图案 程序 中,我们用 while 循环 替换了 for 循环 来在每个位置打印星号。有关更多 字母图案星号图案 程序,请使用超链接。

{

int rows, i, j;

System.out.print("Enter Rows = ");
rows = sc.nextInt();

i = 0;
while ( i < rows)
{
System.out.printf("*");
j = 0;
while ( j <= rows)
{
if ((j == rows) || (j == i && j < rows / 2)
|| (j == rows - i - 1 && j > rows / 2))
{
System.out.printf("*");
}
else
{
System.out.printf(" ");
}
j++;
}
System.out.println();
i++;
}
}
}
Enter Rows = 15

在此程序中,我们创建了一个 AlphabetMShape 函数来打印由星号填充的字母 M 图案或形状,该形状具有行和列。

import java.util.Scanner;

public class Example
{
private static Scanner sc;

public static void main(String[] args)
{
sc = new Scanner(System.in);

System.out.print("Enter Rows = ");
int rows = sc.nextInt();

System.out.print("Enter Character = ");
char a = sc.next().charAt(0);

AlphabetMShape(rows, a);
}

public static void AlphabetMShape(int rows, char a)
{
for (int i = 0; i < rows; i++)
{
System.out.printf("%c", a);

for (int j = 0; j <= rows; j++)
{
if ((j == rows) || (j == i && j < rows / 2)
|| (j == rows - i - 1 && j > rows / 2))
{
System.out.printf("%c", a);
}
else {
System.out.printf(" ");
}
}
System.out.println();
}
}
}
