1. Write a Java program that inputs a document and ten outputs a bar-chart plot of the frequencies of each alphabet character that appears within that document.

Solution

import java.io.File;
import java.io.IOException;
import java.util.Map;
import java.util.Scanner;
import java.util.TreeMap;

public class Test {

   public static void main(String[] args) throws IOException {
Map<Character, Integer> chars = new TreeMap<Character, Integer>();
Scanner scan = null;

try {
   scan = new Scanner(new File(\"D:/abc.txt\"),\"utf-8\");

while (scan.hasNext()) {
char[] line = scan.nextLine().toLowerCase().toCharArray();

for (Character character : line) {
if (Character.isLetter(character)){
if (chars.containsKey(character)) {
   chars.put(character, chars.get(character) + 1);
} else {
   chars.put(character, 1);
}
}
}
}
} finally {
if (scan != null){
   scan.close();
}
}

if (!chars.isEmpty()){
for (Map.Entry<Character, Integer> entry : chars.entrySet()) {
System.out.println(entry.getKey() + \": \" + entry.getValue());
}
}
}
}
