Program to check if given alphabet is upper or lower case in Java

Program to check if given alphabet is upper or lower case in Java

In this article, we will discuss the concept of Program to check if given alphabet is upper or lower case in Java

In this post, we are going to learn how to write a program to  check whether given English alphabet is Upper case or Lower case using if else in Java language

Code to check given Alphabet is Upper or Lower

Code to check given Alphabet is Upper or Lower, using  if  else

In this code, we are going to learn how to check  the given  English alphabet is Upper case or Lower case using if-else statements in Java language

Program 1

import java.util.Scanner;
public class Check_UpperLower1{
public static void main(String args[]){
  char ch;//declare aa character variable 

 Scanner scan=new Scanner(System.in); 
  //create a scanner object for input
  
System.out.println("Enter a Alphabet only to check upper or lower :");
ch=scan.next().charAt(0);;// reading the input from the user

if(ch>='A' && ch<='Z'){
  System.out.println(ch+" is an upper case letter ");
}//check upper case letter
else{
  System.out.println(ch+" is a lower case letter ");
}//print lower case letter
}
}

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

Case 1

Enter a Alphabet only to check upper or lower :
A
A is an Upper  case  letter

Case 2

Enter a Alphabets only to check upper or lower :
s
s is a Lower case letter

 

Code to check given Alphabet is Upper or Lower, using Ascii

In this code, we are going to learn how to check  the given  English alphabet is Upper case or Lower case

using Ascii value in Java language

Program 2

import java.util.Scanner;
public class Check_Upper_Lower1{
public static void main(String args[]){
  char ch;//char variable declaration

 Scanner scan=new Scanner(System.in); 
  //create a scanner object for user input
  
System.out.println("Enter a Alphabet only to check upper or lower: ");
ch=scan.next().charAt(0);;// reading the input from the user

if(ch>=65 && ch<=90){
  System.out.println(ch+" is an upper case letter ");
}//check upper case Alphabe
else{
  System.out.println(ch+" is a lower case letter ");
}//display the lower Alphabets
}
}

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

Case 1

Enter a Alphabet only to check upper or lower :
A
A is an Upper  case  letter

Case 2

Enter a Alphabet only to check upper or lower :
s
s is a Lower  case  letter
