Regular Expression for UpperCase Letters In A String

Question

For the life of me, I can\'t figure out why this regular expression is not working. It should find upper case letters in the given string and give me the count. Any ideas are we

Answer 1

In this example i'm using a regex(regular Expression) to count the number of UpperCase and LowerCase letters in the given string using Java.

import java.util.regex.*;
import java.util.Scanner;
import java.io.*;
public class CandidateCode {
    public static void main(String args[] ) throws Exception {
        Scanner sc= new Scanner(System.in);
    //  Reads the String of data entered in a line
        String str = sc.nextLine();

    //counts uppercase letteres in the given String 
        int countuc = str.split("([A-Z]+?)").length; 

    //counts lowercase letteres in the given String 
        int countlc = str.split("([a-z]+?)").length; 

        System.out.println("UpperCase count: "+countuc-1);
        System.out.println("LowerCase count: "+countlc-1);
   }
}
