Java 打印字母 S 图案的程序

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

在此字母 S 形状或图案程序中,我们将for 循环替换为while 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。

import java.util.Scanner;

public class Example
{
private static Scanner sc;

public static void main(String[] args)
{
sc = new Scanner(System.in);
int rows, i, j;

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

i = 0;
while ( i < rows)
{
j = 0;
while ( j < rows)
{
if (i == 0 || i == rows / 2 || i == rows - 1)
{
System.out.printf("* ");
}
else if (((j == 0) && (i < rows / 2 )) || (j == rows - 1 && i > rows / 2))
{
System.out.printf("* ");
}
else
{
System.out.printf(" ");
}
j++;
}
System.out.println();
i++;
}
}
}
Enter Rows = 16

*                               
*                               
*                               
*                               
*

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

在此程序中,我们创建了一个 AlphabetSShape 函数来打印用星号填充的字母 S 图案或形状(在行和列上)。

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);

AlphabetSShape(rows, a);
}

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