Java program to print alphabets

Let’s learn java program to print alphabets.

Here we are going to show you few methods to print alphabets in java. To begin with let’s see java program to print alphabets in lowercase,

Java program to print alphabets from a to z : using for loop

public class PrintAlphabetsInJava
{
   public static void main(String[] args)
   {
      System.out.println("Printing alphabets from a to z : "); 
      char alphabet;
      for(alphabet = 'a'; alphabet <= 'z'; alphabet++)
      {
         System.out.println(alphabet);
      }
   }
}



Output:

java program to print alphabets

Java program to display characters from a to z using while loop

public class JavaAlphabet
{
   public static void main(String[] args)
   {
      System.out.println("Printing alphabets from a to z : "); 
      char alphabet = 'a';
 
      while(alphabet <= 'z')
      {
         System.out.println(alphabet);
         alphabet++;
      }
   }
}



Output:

Printing alphabets from a to z : 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


Java program to display characters from a to z using do while loop

public class AlphabetInJava
{
   public static void main(String[] args)
   {
      System.out.println("Printing alphabets from a to z : "); 
      char alphabet = 'a';
 
      do
      {
         System.out.println(alphabet);
         alphabet++;
 
      } while(alphabet <= 'z');
   }
}



Output:

Printing alphabets from a to z: 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


However, above java example to print all alphabets can also be used to print few alphabets, that is, from alphabet ‘a’ to alphabet ‘m’.

Also read – variables in java

public class JavaPrintAlphabet
{
   public static void main(String[] args)
   {
      System.out.println("Printing alphabets from a to m : ");
      char alphabet = 'a';
 
      do
      { 
         System.out.println(alphabet);
         alphabet++;
      } while(alphabet <= 'm');
   }
}



Output:

Printing alphabets from a to m : a b c d e f g h i j k l m


Meanwhile, we can also write java program to display all alphabets from A to Z in uppercase,

public class JavaPrintAlphabet
{
   public static void main(String[] args)
   {
      System.out.println("Printing alphabets from A to Z : "); 
      char alphabet;
 
      for(alphabet = 'A'; alphabet <= 'Z'; alphabet++)
      {
         System.out.println(alphabet);
      } 
   }
}



Output:

Printing alphabets from A to Z : 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
