Java Program to Display Alphabets (A to Z) using loop

Example 1: Display uppercased alphabet using for loop

class Main {
  public static void main(String[] args) {

    char c;

    for(c = 'A'; c <= 'Z'; ++c)
      System.out.print(c + " ");
    }
}

Output

A B C D E F G H I J K L M N O P Q R S T U V W X Y Z 

You can loop through A to Z using for loop because they are stored as ASCII characters in Java.

So, internally, you loop through 65 to 90 to print the English alphabets.

With a little modification, you can display lowercase alphabets as shown in the example below.

Example 2: Display lowercase alphabet using for loop

class Main {
  public static void main(String[] args) {

    char c;

    for(c = 'a'; c <= 'z'; ++c)
      System.out.print(c + " ");
    }
}

Output

a b c d e f g h i j k l m n o p q r s t u v w x y z 

You simply replace A with a and Z with z to display the lowercase alphabets. In this case, internally you loop through 97 to 122.
