Display the Alphabet A to Z in Java

public class DisplayCharacters {
  
     public static void main(String[] args) {
  
         char alphabet;
  
         for(alphabet = 'A'; alphabet <= 'Z'; ++alphabet)
             System.out.print(alphabet + " ");
     }
} 

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 

• This program is used for displaying all the characters (uppercase letters) from A to Z by using a for loop.
• Initially, only a single character variable alphabet is initialized.
• A for loop is set by giving it a condition of iterating from the ASCII value of A till the ASCII value of Z. This looping through characters is possible because the characters are stored in the form of ASCII values in Java.
• The increment in the character variable continues along with the printing of the characters until Z is reached. The loop initiates from the value 65 since ASCII value of A is 65 and up to 90 which is the ASCII value of Z.

• This program is used for displaying all the characters (lowercase letters) from a to z by using a for loop.
• Initially, only a single character variable alphabet is initialized.
• A for loop is set by giving it a condition of iterating from the ASCII value of a till the ASCII value of z. This looping through characters is possible because the characters are stored in the form of ASCII values in Java.
• The increment in the character variable continues along with the printing of the characters until z is reached. The loop initiates from the value 65 since ASCII value of a is 97 and up to 122 which is the ASCII value of z.
