Sir not getting this?

#1

import java.util.Scanner;

class Patterntry {
public static void main(String args[]) {
Scanner scn = new Scanner(System.in);
String str = scn.nextLine();
if (str >=“a” && str <=“z”) {
System.out.println(“lowercase”);
} else if (str >= “A” && str <= “Z”) {
System.out.println(“UPPERCASE”);
} else {
System.out.println(“Invalid”);
}

}

}

@Harsh_Sonwani,
https://ide.codingblocks.com/s/265494 corrected code.

For characters use single quotes ( ’ ’ ) instead of double quotes (" ").

For single char input we do:
char str = scn.next().charAt(0);

You were taking input as string and then comparing the string with another string “a” and “z”. Which is wrong.
