Java Program to Print Alphabet L Pattern

In this Java pattern program, we show the steps to print the stars in an Alphabet L shape or pattern using for loop, while loop, and functions.

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 - 1)
{
System.out.printf("*");
}
else
{
System.out.printf(" ");
}
}
System.out.println();
}
}
}
Enter Rows = 15

*                
*                
*                
*                
*                
*                
*                
*                
*                
*

*

Within this Alphabet L shape or Pattern program, we replaced the for loop with a while loop to print the stars at each position. For more Alphabet Patterns and star pattern programs, please use the hyperlinks.

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 - 1)
{
System.out.printf("*");
}
else
{
System.out.printf(" ");
}
j++;
}
System.out.println();
i++;
}
}
}
Enter Rows = 17

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

In this program, we created an AlphabetLShape function to print the Alphabet L Pattern or shape filled with stars on rows and columns.

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);

AlphabetLShape(rows, a);
}

public static void AlphabetLShape(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 - 1)
{
System.out.printf("%c", a);
}
else {
System.out.printf(" ");
}
}
System.out.println();
}
}
}
