Alphabet Pattern (or) Character Pattern3 Program in Java

Write "C"  Program to print below Alphabet Pattern3 (or) Character Pattern3:

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

·  Java For loop
·   Java programming operators.

Java Character pattern3 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)(j+64));
        }
        System.out.println();
    }
  }
Output:
Enter the number of lines 5 A AB ABC ABCD ABCDE
Explanation:
  • 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 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"k" value the program terminates.
