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)
