Java program to print all alphabets in given range using loops

Java program to print all alphabets in given range using loops

In this article, we will discuss the concept of Java program to print all alphabets in given range using loops

In this post, we are going to learn how to write a program to  print all alphabets in given range using  for, while and do-while  loop in Java language

Code to print all alphabets in given range

Code to print all alphabets in given range using for loop

In this code, we are going to learn how to print all alphabets in given range using for loop in Java language

Program 1

import java.util.Scanner;
public class Display_Alphabet_Letters{
public static void main(String args[]){
char ch,ch1,ch2;// declare character variable
 Scanner scan=new Scanner(System.in); 
  //create a scanner object for input
  
System.out.print("Enter the Starting Alphabets: ");
//ask starting alphabet from user
ch1=scan.next().charAt(0);
//Reading starting alphabets from user
System.out.print("Enter the Ending Alphabets ");
//ask ending alphabet from user
ch2=scan.next().charAt(0);
//Reading ending alphabets from user

System.out.print("Display Alphabets between"+ch1+" and "+ch2+" : \n");
for(ch=ch1; ch<=ch2; ch++){
System.out.print(ch+" ");
//display uppercase Alphabets with space using for loop
}
}

}

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

Enter the Starting Alphabets: C
Enter the Ending Alphabets: M
Display Alphabets between C and M :
C  D  E  F  G  H  I  J  K  L  M

 

Code to print all alphabets in given range using while loop

In this code, we are going to learn how to print all alphabets in given range using while loop in Java language

Program 2

import java.util.Scanner;
public class Disp_Alphabet_Let1{
public static void main(String args[]){
char ch,ch1,ch2;// declare character variable
 Scanner scan=new Scanner(System.in); 
  //create a scanner object for input
  
System.out.print("Enter the Starting Alphabets ");
//ask starting alphabet from user
ch1=scan.next().charAt(0);
//Reading starting alphabets from user
System.out.print("Enter the Ending Alphabets ");
//ask ending alphabet from user
ch2=scan.next().charAt(0);
//Reading ending alphabets from user

System.out.print("Display Alphabets between "+ch1+" and "+ch2+" : \n");
ch=ch1; 
while(ch<=ch2){
System.out.print(ch+" ");
//display uppercase Alphabets with space using while loop
ch++;
}
}

}

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

Enter the Starting Alphabets: S
Enter the Ending Alphabets: Z
Display Alphabets between S and Z :
S   T   U    V    W     X    Y    Z

 

Code to print all alphabets in given range using do-while loop

In this code, we are going to learn how to print all alphabets in given range using do-while loop in Java language

Program 3

import java.util.Scanner;
public class Disp_Alphabet_Let2{
public static void main(String args[]){
char ch,ch1,ch2;// declare character variable
 Scanner scan=new Scanner(System.in); 
  //create a scanner object for input
  
System.out.print("Enter the Starting Alphabets ");
//ask starting alphabet from user
ch1=scan.next().charAt(0);
//Reading starting alphabets from user
System.out.print("Enter the Ending Alphabets ");
//ask ending alphabet from user
ch2=scan.next().charAt(0);
//Reading ending alphabets from user

System.out.print("Display Alphabets between "+ch1+" and "+ch2+" : \n");
ch=ch1; 
do{
System.out.print(ch+" ");
//display uppercase Alphabets with space using do-while loop
ch++;
}while(ch<=ch2);
}

}

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

Enter the Starting Alphabets: D
Enter the Ending Alphabets: M
Display Alphabets between D and M :
D   E   F    G    H    I    J    K   L    M
