Java Program to Print Alphabets from A to Z

Write a Java Program to Print Alphabets from A to Z using for loop. In this example, for loop will iterate from alphabets A to Z and print them as an output.

public class AlphabetsAtoZ {

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

This program iterates the ASCII codes from 65 to 90, representing the alphabets A to Z, and prints them. Here, we used for loop, while loop, and do while loop to show you the possibilities.

public class AlphabetsAtoZ2 {

	public static void main(String[] args) {
			
		for(int i = 65; i <= 90; i++) 
		{
			System.out.printf("%c ", i);
		}
		System.out.println();
		
		
		int j = 65;
		while(j <= 90) 
		{
			System.out.printf("%c ", j);
			j++;
		}	
		System.out.println();
		
		
		int k = 65;
		do 
		{
			System.out.printf("%c ", k);
		}	while(++k <= 90);
	}
}

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 

This program allows the user to enter the starting alphabet A and print the remaining uppercase alphabets up to Z.

import java.util.Scanner;

public class AlphabetsAtoZ3 {
	
	private static Scanner sc;

	public static void main(String[] args) {
			
		char ch, strChar;
		sc= new Scanner(System.in);

		System.out.print("Please Enter any Character =  ");
		strChar = sc.next().charAt(0);
		
		for(ch = strChar; ch <= 'Z'; ch++) {
			System.out.print(ch + " ");
		}
	}
}

Please Enter any Character =  G
G H I J K L M N O P Q R S T U V W X Y Z
