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) + " ");
}
System.out.println();
}
}
}
Output
** Printing the pattern... ** A A B A B C A B C D A B C D E A B C D E F
