Java 打印字母 F 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 循环和函数打印字母 F 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 ((i == 0) || (i == rows / 2 && j <= rows / 2))
{
System.out.printf("*");
}
else
{
System.out.printf(" ");
}
}
System.out.println();
}
}
}
Enter Rows = 15

在此字母 F 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形图案程序,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)
{
System.out.printf("*");
j = 0;
while ( j < rows)
{
if ((i == 0) || (i == rows / 2 && j <= rows / 2))
{
System.out.printf("*");
}
else {
System.out.printf(" ");
}
j++;
}
System.out.println();
i++;
}
}
}
Enter Rows = 13

在此程序中,我们创建了一个 AlphabetFShape 函数来打印由星号填充的字母 F 图案或形状,跨越行和列。

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);

AlphabetFShape(rows, a);
}
public static void AlphabetFShape(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 == 0) || (i == rows / 2 && j <= rows / 2))
{
System.out.printf("%c", a);
}
else {
System.out.printf(" ");
}
}
System.out.println();
}
}
}
