I wrote a program like this 


 Scanner in = new Scanner(System.in);
   System.out.println("Input a letter"); 
   String line = in.nextLine();
   char c = line.charAt(0);
   if( character.isDigit(c))
   System.out.println(c +" Is a digit");
   else if (character.isLetter(c))
   System.out.println(c +" Is a Letter");

And It gives me error.

How can I solve this problem?

In your program you declared Character as character .
You should have programmed like below:

if (Character.isdigit(c)){
 System.out.println(c +" Is a digit");
}
else if (Character.isdigit(c)){
 System.out.println(c +" Is a digit");
}

You can also try this:

     System.out.println("Enter the value");
        String data;
        data = in.next();

        int len = data.length();
        for (int i = 0 ; i < len ; i++){
            char ch = data.charAt(i);

            if ((ch >= '0' && ch <= '9')){
                System.out.println("Number ");
            }
            else if((ch >= 'a' && ch <= 'z') || (ch >= 'A' && ch <= 'Z')){
            System.out.println("Character");
            }
            else{
                System.out.println("Symbol");
             }
        }
