Alphabet Pattern 2 (or) Character Pattern 2 Program in Java ~ Tutorialsweb

Write "Java" program to print below Alphabet Pattern 2 (or) Character pattern 2:

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

· Java For loop
· Java programming operators.

Java Character pattern2 program using For loop:

import java.util.Scanner;

class alphabetPattern1

public static void main(String[] ags)

    int i, j,k;

   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 <= i;j++)

            System.out.print((char)(k-i+1+64));

        System.out.println();

Output:


Enter the number of lines
5
E
DD
CCC
BBBB
AAAAA

Explanation:

The first three integers "i", "j" and "k" are declared of type int.
Then in the First for loop “i” value is initialized with a value 1.
Now “i” value is checked with the condition i < k that is (where 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 <= i. Where "j = 1". and the condition is True.
Now prints the " Alphabet". Print up to second for loop condition becomes False.
when the value of "i" becomes greater than the "k" value the program terminates.
