Java 程序打印字母 H 形状

在这个 Java 模式程序中,我们展示了如何使用 for 循环、while 循环和函数来打印字母 H 形状或模式的星号。

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 (i == rows / 2 || j == rows - 1)
{
System.out.printf("*");
}
else
{
System.out.printf(" ");
}
}
System.out.println();
}
}
}
Enter Rows = 15
*              *
*              *
*              *
*              *
*              *
*              *
*              *
****************
*              *
*              *
*              *
*              *
*              *
*              *

在此字母 H 形状或模式 程序 中,我们用 while 循环 替换了 for 循环 以在每个位置打印星号。有关更多 字母模式星形模式 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 )
{
System.out.printf("*");
j = 0;
while ( j < rows)
{
if (i == rows / 2 || j == rows - 1)
{
System.out.printf("*");
}
else
{
System.out.printf(" ");
}
j++;
}
System.out.println();
i++;
}
}
}
Enter Rows = 12

在此程序中,我们创建了一个 AlphabetHShape 函数来打印用星号填充的字母 H 模式或形状(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);

AlphabetHShape(rows, a);
}

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