//import java.uitl.regex.;
public class Main {
public static void main(String args[]) {
Scanner cin = new Scanner(System.in);
char ch = cin.nextChar();
Pattern pt = Pattern.compile("[^a-z]");
Matcher match= pt.matcher©;
Pattern pt1 = Pattern.compile("[^A-Z]");
Matcher match1= pt1.matcher©;
if(match.isFind()){
System.out.println(“lowercase”);
}else if(match1.isFind()){
System.out.println(“UPPERCASE”);
}else{
System.out.println(“Invalid”);
}

}

}

You don’t have to necessarily use Regex in this question. It can be solved using ASCII values. And use import java.util.*; to import java util package. And in Scanner class, there is no nextChar(), hence use cin.next().charAt(0) to input a char. It takes input as a string and the charAt(0) function returns the first char.
