Java: The current code uses a hashset to count the amount of total vowels in my textfile. How can I adjust it to count each vowel individually instead of the the total. import java.io.*; import java.util.Arrays; import java.util.HashSet; import java.util.Scanner; public class Number2 { static String fileName = \"E:\\\\Lincoln.txt\"; public static void main(String[] args) throws IOException { int vowelCount = 0; try (BufferedReader in = new BufferedReader(new FileReader(fileName))) { HashSet vowels = new HashSet<>(Arrays.asList(new Character[] { \'A\', \'E\', \'I\', \'O\', \'U\' })); String s; while ((s = in.readLine()) != null) { for (char ch : s.toCharArray()) { if (Character.isAlphabetic(ch)) { ch = Character.toUpperCase(ch); if (vowels.contains(ch)) vowelCount++; } } } } catch (IOException ex) { } System.out.println(\"Total vowels = \" + vowelCount); } } Solution
Number2.java
import java.io.*;
public class Number2 {
static String fileName = \"D:\\\\Lincoln.txt\";
public static void main(String[] args) throws IOException {
//int vowelCount = 0;
int letterACount = 0;
int letterBCount = 0;
int letterCCount = 0;
int letterDCount = 0;
int letterECount = 0;
try {
BufferedReader in = new BufferedReader(new FileReader(fileName));
String s;
while ((s = in.readLine()) != null) {
for (char ch : s.toCharArray()) {
if (Character.isAlphabetic(ch)) {
ch = Character.toUpperCase(ch);
if(ch==\'A\'){
letterACount++;
}
else if(ch==\'B\'){
letterBCount++;
}
else if(ch==\'C\'){
letterCCount++;
}
else if(ch==\'D\'){
letterDCount++;
}
else if(ch==\'E\'){
letterECount++;
}
}
}
}
System.out.println(\"Letter A Count: \"+letterACount);
System.out.println(\"Letter B Count: \"+letterBCount);
System.out.println(\"Letter C Count: \"+letterCCount);
System.out.println(\"Letter D Count: \"+letterDCount);
System.out.println(\"Letter E Count: \"+letterECount);
} catch (IOException ex) {
}
}
}
Output:
Letter A Count: 2
Letter B Count: 2
Letter C Count: 1
Letter D Count: 2
Letter E Count: 2
