Write "Java" Program to print below Alphabet Pattern18 (or) Character Pattern18:

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

· Java if Else Statement.

· Java For loop
· Java programming operators.

Java Character pattern 18 programs using For loop:

import java.util.Scanner;

class alphabetPattern18

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 = k;j >= i;j--)

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

        System.out.println();

Output:


Enter the number of lines

Explanation:

The first three integers "i", "j", "k" 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 >= i". Where "j = k". and the condition is True.
Now prints the " Alphabet". Print up to second for loop condition becomes False.
When the value of "k" becomes less than the "i" value the program terminates.
