Write a program that reads a file one character at a time and
prints out how many characters are uppercase letters, lowercase
letters, digits, white space, and something else.
import java.io.File;
import java.io.FileNotFoundException;
import java.io.PrintWriter;
import java.util.Scanner;
public class Characters
{
public static void main(String[] args) throws
FileNotFoundException
{
Scanner console = new
Scanner(System.in);
System.out.print("Input file: ");
String inputFileName = console.next();
File inputFile = new
File(inputFileName);
Scanner in = new Scanner(inputFile);
in.useDelimiter("");
int uppercase = 0;
int lowercase = 0;
int digits = 0;
int whitespace = 0;
int other = 0;
char ch;
String line;
Scanner fin = new Scanner(new
File(inputFileName));
while (fin.hasNextLine())
{
line = fin.nextLine();
for (int i = 0; i <
line.length(); i++)
{
ch =
line.charAt(i);
if
(Character.isUpperCase(ch)) { uppercase++; }
else if
(Character.isLowerCase(ch)) { lowercase++; }
else if
(Character.isDigit(ch)) { digits++; }
else if
(Character.isSpaceChar(ch)) { whitespace++; }
else other++;
}
}
fin.close();

System.out.println("Uppercase: " +
uppercase);
System.out.println("Lowercase: " +
lowercase);
System.out.println("Digits: " + digits);
System.out.println("Whitespace: " +
whitespace);
System.out.println("Other: " + other);
}
}
