In this article, we will learn to print the different Alphabet Pattern Programs in Java. This is one among the popular Java interview questions for fresher. Lets look into the below possible Alphabet / Character Pattern Programs in Java.
Alphabet Pattern Programs in Java
Pattern 1:
package com.javainterviewpoint;
public class Pattern1
{
public static void main(String[] args)
{
int alphabet = 65;
System.out.println("** Printing the pattern... **");
for (int i = 0; i <= 5; i++)
{
for (int j = 0; j <= i; j++)
{
System.out.print((char) (alphabet + j) + " ");

Hope the above pattern programs helped you. Do post the patterns which needs to be added in the comments. Happy Learning !! 🙂
I didn’t find the below type of pattern
A
BA
CBA
DCBA
Here you go
String[] val = {“A”, “B”, “C”, “D”, “E”};
for(int i=0;i<5;i++)
{
for(int j=i; j>=0; j–)
{
System.out.print(val[j]);
}
System.out.println();
}
