Here you will see, How to prints Alphabets through Java all loops (for, While and do while). In these loops we are just increments char value and characters are increment continuously.

public class PrintAlphabets {

public static void main(String[] args) {
// By for Loop
char ch;
for (ch = 'a'; ch <= 'z'; ch++) {
System.out.print(ch + " ");
}
System.out.println();

// By While loop
char c = 'a';

while (c <= 'z') {
System.out.print(c + " ");
c++;
}
System.out.println();

// By do while loop
c = 'A';

do {
System.out.print(c + " ");
c++;
} while (c <= 'Z');
}

}

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
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
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
