The following FileUtils.readFile takes a file path, and a second paramter charset – then it will read the content of the file and return as a string. This is a handy method similar to file_get_contents in PHP.
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 | class FileUtils { public static String readFile(String path, String charSet) { var s = new StringBuffer(); if (charSet == null || charSet.isBlank() || charSet.isEmpty()) { charSet = "UTF-8"; } try (var reader = new BufferedReader(new InputStreamReader(new FileInputStream(path), charSet))) { var ts = ""; while ((ts = reader.readLine()) != null) { s.append(ts + System.lineSeparator()); } return s.toString(); } catch (IOException e) { System.err.println(e); } return null; } } |
class FileUtils {
public static String readFile(String path, String charSet) {
var s = new StringBuffer();
if (charSet == null || charSet.isBlank() || charSet.isEmpty()) {
charSet = "UTF-8";
}
try (var reader = new BufferedReader(new InputStreamReader(new FileInputStream(path), charSet))) {
var ts = "";
while ((ts = reader.readLine()) != null) {
s.append(ts + System.lineSeparator());
}
return s.toString();
} catch (IOException e) {
System.err.println(e);
}
return null;
}
}The charset if left blank or null, will be set to “UTF-8”. The file is opened via FileInputStream, InputStreamReader and BufferedReader. And the content is put into a StringBuffer.
