Example 1: Java Program to Check Alphabet using if else
public class CheckAlphabet {
public static void main(String[] args) {
//declare a variable
char c = 'E';
//check if c is an alphabet
if( (c >= 'a' && c <= 'z') || (c >= 'A' && c <= 'Z'))
System.out.println(c + " is an alphabet.");
else
System.out.println(c + " is not an alphabet.");
}
}
Output
E is an alphabet.
Example 2: Java Program to Check Alphabet using ternary operator
public class CheckAlphabet {
public static void main(String[] args) {
//declare a variable
char c = '*';
//check if c is an alphabet or not
String output = (c >= 'a' && c <= 'z') || (c >= 'A' && c <= 'Z')
? c + " is an alphabet."
: c + " is not an alphabet.";
System.out.println(output);
}
}
Output
* is not an alphabet.
Example 3: Java Program to Check Alphabet using isAlphabetic() Method
class CheckAlphabet {
public static void main(String[] args) {
// declare a variable
char c = 'a';
// check if c is an alphabet
if (Character.isAlphabetic(c)) {
System.out.println(c + " is an alphabet.");
}
else {
System.out.println(c + " is not an alphabet.");
}
}
}
Output
a is an alphabet.
