Java Program to Print Alphabets from A to Z

In the previous article we have discussed about Java Program to Find ASCII Value of a Character

In this article we are going to see how to print/display all the alphabets using Java

Java Program to Print Alphabets from A to Z

We have 26 alphabets starting from “A” to “Z” or “a” to “z”. So we have to run a loop from “A” to “Z” so that we can get all the alphabets in output.

Method-1: Java Program to Print Alphabets from A to Z By Using For Loop

Approach:

  • Taking a character variable as ch.
  • Start a for loop and the value of ch should be initiated with “A” or “a” and goes up to “Z” or “z”.
  • The value of ch is increasing by one in the for loop.
  • Inside the for loop we are continuously print the value of ch so that we get the result.

Program:

class Main
{
    public static void main(String args[])
    {
        char ch;
        //using for loop start from ‘A’ and continue upto ‘Z’
        for(ch= 'A';ch<='Z';++ch)
        System.out.print(ch+" ");
    }
}
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

Method-2: Java Program to Print Alphabets from A to Z By Using While Loop

Approach:

  • Define a method called computeValue() without any argument.
  • In method definition create a character variable named as ch and assigned a value “A” or “a” to it.
  • Now create a while loop and inside the while loop’s condition put ch<=’Z’ or ch<=’z’.
  • Giving a print statement inside the while loop so that it will print all the value of ch throughout the loop.
  • Now just call this method in main function.
  • Print the result.

Program:

class Main
{
    //define a method
    public static void computeValue()
    {
        //initiate the value of ch
        char ch= 'A';
        //declaring while loop
        while(ch<='Z')
        {
            System.out.print(ch+" ");
            ch+=1;
        }
    }
    public static void main(String args[])
    {
        computeValue();
    }
}
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
