Write a Java program to print downward triangle of mirrored alphabets pattern using for loop.
package Alphabets;
import java.util.Scanner;
public class DownwardTriMirrorAlp1 {
private static Scanner sc;
public static void main(String[] args) {
sc = new Scanner(System.in);
System.out.print("Enter Downward Triangle of Mirrored Alphabets Rows = ");
int rows = sc.nextInt();
System.out.println("The Downward Triangle of Mirrored Alphabets Pattern");
int alphabet = 65;
for (int i = 0; i <= rows - 1; i++ )
{
for (int j = i; j <= rows - 1; j++ )
{
System.out.print((char)(alphabet + j) + " ");
}
for(int k = rows - 2; k >= i; k--)
{
System.out.print((char)(alphabet + k) + " ");
}
System.out.println();
}
}
}
In this Java example pattern, we used the while loop to display the downward triangle pattern of mirrored alphabets. For more Alphabet examples, refer to the Java Alphabet Pattern Programs article.
package Alphabets;
import java.util.Scanner;
public class DownwardTriMirrorAlp2 {
private static Scanner sc;
public static void main(String[] args) {
sc = new Scanner(System.in);
System.out.print("Enter Downward Triangle of Mirrored Alphabets Rows = ");
int rows = sc.nextInt();
System.out.println("Printing Downward Triangle of Mirrored Alphabets Pattern\n");
int alphabet = 65;
int j, k, i = 0;
while( i <= rows - 1 )
{
j = i;
while(j <= rows - 1 )
{
System.out.print((char)(alphabet + j) + " ");
j++;
}
k = rows - 2;
while(k >= i)
{
System.out.print((char)(alphabet + k) + " ");
k--;
}
System.out.println();
i++;
}
}
}
Enter Downward Triangle of Mirrored Alphabets Rows = 15
