I need to create a method that reads a html file then display the number of word occurrence.
for example: String [] words = {“happy”, “nice”, “good”};
The word happy was used 7 times. The word nice was used 1 times. The word happy was used 2 times.
This is what I did:
public static void ReadWriteDisplay() {
Path in = Paths.get("E:\TextToHTML.html");
Path out = Paths.get("E:\HTMLToText.txt");
String s = "";
String str = "";
try {
InputStream input = new BufferedInputStream(Files.newInputStream(in));
BufferedReader reader = new BufferedReader(new InputStreamReader(input));
OutputStream output = new BufferedOutputStream(Files.newOutputStream(out, CREATE, WRITE, TRUNCATE_EXISTING));
BufferedWriter writer = new BufferedWriter(new OutputStreamWriter(output));
s = reader.readLine();
while(s != null) {
str += s;
writer.write(s);
writer.newLine();
s = reader.readLine();
}
reader.close();
writer.close();
String a[] = str.split(" ");
System.out.println("str: "+str);
String [] positive = {"happy", "nice", "good", "joy", "love"};
int [] count = {0, 0, 0, 0, 0};
for (int i = 0; i < a.length; i++) {
if(positive[0].equalsIgnoreCase(a[i]))
count[0]++;
if(positive[1].equalsIgnoreCase(a[i]))
count[1]++;
if(positive[2].equalsIgnoreCase(a[i]))
count[2]++;
if(positive[3].equalsIgnoreCase(a[i]))
count[3]++;
if(positive[4].equalsIgnoreCase(a[i]))
count[4]++;
}
for (int x = 0; x < 5; x++) {
System.out.println("The word "+positive[x]+" was used "+count[x]+" times.");
}
} catch(Exception e) {
System.err.println("Message: "+ e);
}
}
My method runs but it does not provide accurate number of occurrence. The reason because some words in html are enclosed in <> which caused <>Hello<> to be stored in my string array instead of the word Hello.
Here is the sample output:
str: <!DOCTYPE html><html lang="en"><head> <meta charset="utf-8"> <meta http-equiv="X-UA-Compatible" content="IE=edge"> <meta http-equiv="Content-Type" content="text/html; charset=utf-8"/> <meta http-equiv="content-language" content="en" /> <meta name="viewport" content="width=device-width, initial-scale=1"> <meta name="google-site-verification" content="rUp8isOBygjhxPJ2qyy6QtBi9vWRFhIboMXucJsCtrE" /> <title>JustPaste.it - Share Text & Images the Easy Way</title> <link rel="preload" href="/static/img/jp_logo_1_en_v4.png" as="image" /> <meta name="robots" content="noindex, nofollow" /> <meta name="googlebot" content="noindex, nofollow" /> <link rel="preload" href="/build/global.395f53d0.css" as="style" /> <link rel="stylesheet" type="text/css" href="/build/global.395f53d0.css" /> <link rel="shortcut icon" href="/static/other/fav.ico" /> <!-- HTML5 shim and Respond.js for IE8 support of HTML5 elements and media queries --> <!-- WARNING: Respond.js doesn't work if you view the page via file:// --> <!--[if lt IE 9]> <script src="https://oss.maxcdn.com/html5shiv/3.7.3/html5shiv.min.js"></script> <script src="https://oss.maxcdn.com/respond/1.4.2/respond.min.js"></script> <![endif]--> <script> window.article = {"id":42017684,"url":"https://justpaste.it/6fn9m","shortUrl":"https://jpst.it/2wiek","pdfUrl":"https://justpaste.it/6fn9m/pdf","qrCodeData":"data:image/png;base64,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"};

Answer
This will help you to remove special characters, this will only allow alphabets for example : <>Hello<> will be replaced like Hello
String alphaOnly = input.replaceAll(“[^a-zA-Z]+”,””);
