Alphabet Pattern 19 (or) Character Pattern 19 Program in Java ~ Tutorialsweb

Write "Java" Program to print below Alphabet Pattern19 (or) Character Pattern19:

To understand this example, you should have knowledge of the following topics:

· Java For loop
· Java programming operators.

Java Character pattern 19 programs using For loop:

import java.util.Scanner;

class alphabetPattern19

public static void main(String[] ags)

    int i, j,k,n;

   System.out.println("Enter the number of lines");

   Scanner s = new Scanner(System.in);

   k = s.nextInt();

    for(i = 1;i <= k;i++)

        for(j = 1;j <= k-i;j++)

            System.out.print(" ");

           for( n = 1; n <= i; n++)

            System.out.print((char)(i+64));

        System.out.println();

Output:


Enter the number of lines
5

       A

      BB

   CCC

 DDDD

EEEEE

Explanation:

First four integers "i", "j", "k","n" are declared of type int.
Then in the First for loop “i” value is initialized with a value of "1".
Now “i” value is checked with the condition "i <= k" (where the "k" value is given through Keyboard). If the condition is True loops enter into second for loop.
Now the loop enters into the second for loop and checks the condition "j <= k-i". Where "j = 1". and the condition is True prints the statement.
Now the loop enters into third for loop and checks the condition "j <= i". Where "n = 1". and the condition is True prints the statement.
Now prints the " Alphabet". Print up to third for loop condition becomes False.
When the value of "k" becomes less than the "i" value the program terminates.
