comparing character in java: uppercase, lowercase, or symbol?

[mark donner]

Hi

I am trying to learn java. What is wrong with my code below. Thank you very much for your help!

(program is for java to tell what kind of character it is)

import java.util.Scanner;

public class test
{
    public static void main (String[] args)
    {
        Scanner keyboard = new Scanner (System.in);
        System.out.println("please enter a character to test");
        char example = keyboard.nextLine().charAt(0);
        printTypeOfChar(example);
    }



    public static void printTypeOfChar(char example)
    {
        if("a" <= example && example<= "z")
            System.out.println ("This is a lowercase character");
        else if("A" <= example && example<= "Z")
            System.out.println("This is an uppercase character");
        else
            System.out.println("symbol");
    }
}

You can not compare the char with the String , "A" is a String not a char ('A')

Please follow the posting guideline

Below code can solve your problem

public static void main(String[] args)
{
    char  example = 'C';
    if('a' <= example  && example<= 'z') 
        System.out.println ("This is a lowercase character"); 
        else if('A' <= example && example<= 'Z') 
        System.out.println("This is an uppercase character"); 
        else 
        System.out.println("symbol"); 

}

You might want to look more carefully at those if statements - there's an error in the logic.

Read carefully through the Character class; you may find something very useful for your problem there.

Thank you very much for everyone's help. Sorry about not doing the codetags.

What wrong with the logic?

thank you

You sure those should both be "<="?
