Java program to display alphabets using loops

In this article, we will discuss the concept of Java program to display all alphabets using loops

In this post, we are going to learn how to write a program to print all characters of English alphabet using for, while and do-while loop in Java language

Code to print all characters of alphabet

Code to print all characters of alphabet using for loop

In this code, we are going to learn how to print all characters of English alphabet using for loop in Java language

Program 1

public class Disp_Alphabet_LetAtoZ{
public static void main(String args[]){
char ch;// declare character variable


System.out.print("Display Uppercase Alphabets  \n");

for(ch='A'; ch<='Z'; ch++){
System.out.print(ch+" ");
//display uppercase Alphabets with space using for loop
}

System.out.print("\n\nDisplay Lowercase Alphabets  \n");

for(ch='a'; ch<='z'; ch++){
System.out.print(ch+" ");
//display lowercase Alphabets with space using for loop
}
}

}

When the above code is executed, it produces the following result

Display Uppercase Alphabets
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

Display Lowercase Alphabets
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

Code to print all characters of alphabet using while loop

In this code, we are going to learn how to print all characters of English alphabet using while loop in Java language

Program 2

public class Disp_Alpha_LetAtoZ{
public static void main(String args[]){
char ch;// declare character variable


System.out.print("Display Uppercase Alphabets  \n");
ch='A'; 
while(ch<='Z'){
System.out.print(ch+" ");
//display uppercase Alphabets with space using while loop
 ch++;
}

System.out.print("\n\nDisplay Lowercase Alphabets  \n");
ch='a'; 
while(ch<='z'){
System.out.print(ch+" ");
//display lowercase Alphabets with space using while loop
ch++;
}
}

}

When the above code is executed, it produces the following result

Display Uppercase Alphabets
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

Display Lowercase Alphabets
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

Code to print all characters of alphabet using do-while loop

In this code, we are going to learn how to print all characters of English alphabet using do-while loop in Java language

Program 3

public class Disp_Alpha_LetterAtoZ{
public static void main(String args[]){
char ch;// declare character variable


System.out.print("Display Uppercase Alphabets  \n");
ch='A'; 
do{
System.out.print(ch+" ");
//display uppercase Alphabets with space using o-while loop
 ch++;
}while(ch<='Z');

System.out.print("\n\nDisplay Lowercase Alphabets  \n");
ch='a'; 
do{
System.out.print(ch+" ");
//display lowercase Alphabets with space using do-while loop
ch++;
}while(ch<='z');
}

}

When the above code is executed, it produces the following result

Display Uppercase Alphabets
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

Display Lowercase Alphabets
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
