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

In this program, you'll learn to print uppercase and lowercase English alphabets using for loop in Java.

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


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.
