Java Program to check input is Digit or Alphabets or Special Character

In this tutorial you will be learning Writing Java Program to check a Given input is either a Digit or an Alphabet or a Symbol.

For Example:

Example 1:

Suppose a given input is 10

Then the output should be “Given input is a digit”.

Example 2:

And for the input A or any character

The output should be “Given input is an Alphabet”.

Example 3:

And for the input “#” or any other Special Character.

The output should be “Given input is a Special Character”.

Program to check input is Digit or Alphabet or Character in Java

import java.util.*;
public class Main
{
  public static void main (String[] args)
  {
    System.out.println("Check if input is Digit/Alphabet/Special Character");
    Scanner sc = new Scanner (System.in);
    System.out.println ("Enter a input");
    char ch = sc.next ().charAt (0);
     if (Character.isLetter(ch)) {
         System.out.println("Given input is an Alphabet.");
     }else if(ch>='0' && ch<='9')
	 {
	  	System.out.println("Given Input is Digit.");
	 } else{
	     System.out.println("Given Input is Special Character.");
	 } 
  }
}

Output 1:

Check if input is Digit/Alphabet/Special Character
Enter a input
34
Given Input is Digit.

Output 2:

Check if input is Digit/Alphabet/Special Character
Enter a input
ww
Given input is an Alphabet.

Output 3:

Check if input is Digit/Alphabet/Special Character
Enter a input
#$
Given Input is Special Character.
