How can i do this?

how do i check if a letter is upper or lower case in java?

The Character class provides static functions to check if a character is upper case or lower case. Just call Character.isUpperCase or Character.isLowerCase.

i did that but it didn't work. here is the code

public static void main(String[] args) {
Scanner reader = new Scanner(System.in);
System.out.println("Put in your letter");
char c = reader.next().charAt(0);
if (Character.isUpperCase); {
System.out.println("your letter is uppercase");
} if (Character.isLowerCase); {
System.out.println("Your letter is lowercase");
}
}

Those are functions, the first argument of which is the character to check. E.g.,

Character.isUpperCase(c)

To check the letter for uppercase or lowercase you need to use the Character. Like for uppercase UpperCase(), method and similar to this for lowercase only change are LowerCase().
