How to output formatted html in java

Question

I read the html file as follows:

try {
    BufferedReader bufferReader = new BufferedReader(new FileReader(path));
    String content;
    while((content = bufferReader.readLine()) != null) {
        result += content;
    }
    bufferReader.close();

} catch (Exception e) {
    return e.getMessage();
}

And I want to display it in a GWT textArea in which I pass it as a String. But the line loses deepenings and is displayed as single-line text. Is there a way to display it properly formatted (with recesses)?

Answer 1

Probably because it readLine()breaks the end of line characters. Add them again for each row.

Also, use StringBuilderinstead of using +=in Stringin a loop:

try {
    BufferedReader bufferReader = new BufferedReader(new FileReader(path));
    StringBuilder sb = new StringBuilder();
    String content;
    while ((content = bufferReader.readLine()) != null) {
        sb.append(content);
        sb.append('\n');   // Add line separator
    }
    bufferReader.close();
} catch (Exception e) {
    return e.getMessage();
}

String result = sb.toString();
