LOWER UPPER -doubt in input

#1

I am not able to understand why i am getting this error. I have attached the code
import java.util.*;
public class Main {
public static void main(String args[]) {
Scanner sc=new Scanner(System.in);
int t=sc.nextInt();
while(t–>0)
{
String s=sc.next();
char a=s.charAt(0);
int b=a;
if(b>=65 && b<=90)
{
System.out.println(“Uppercase”);
}
else if(b>=97 && b<=122)
{
System.out.println(“lowercase”);
}
else
{
System.out.println(“invalid”);
}
}
}
}

Hi @litoriasiddharth,
actually it is not Uppercase but it is UPPERCASE … Like in output all the alphabets must be capital … And it is Invalid not invalid … ‘i’ must be uppercase in this …
