Method

StringreadLine(File file)
read Line 
try (BufferedReader br = new BufferedReader(new FileReader(file))) {
    return br.readLine();
StringreadLine(File file, int lineNumber)
Reads a line from the specified file and lineNumber. 
List<String> records = readRecords(file);
return records.get(lineNumber);
ListreadLine(InputStream in)
read Line 
return readLine(in, "utf-8");
StringreadLine(InputStream in)
read Line 
final BufferedReader reader = new BufferedReader(new InputStreamReader(in));
final StringBuilder out = new StringBuilder();
final String newLine = System.getProperty("line.separator");
String line;
try {
    while ((line = reader.readLine()) != null) {
        out.append(line);
        out.append(newLine);
...
StringreadLine(InputStream input)
Cheesy method which lets us read from an InputStream without having to instantiate a BufferedReader. 
StringBuilder buf = new StringBuilder();
int c;
while ((c = input.read()) >= 0 && c != '\n') {
    buf.append((char) c);
return c >= 0 ? buf.toString() : null;

return c >= 0 ? buf.toString() : null;
StringreadLine(RandomAccessFile wiki)
read Line 
long start = wiki.getFilePointer();
wiki.readLine();
long end = wiki.getFilePointer();
wiki.seek(start);
byte[] b = new byte[(int) (end - start)];
wiki.read(b);
return new String(b).replace(System.lineSeparator(), "");
StringreadLine(Reader rd)
Read a line from an InputStream in human-readable-form as a String. 
String input = "";
while (!Thread.interrupted()) {

    if (ch == -1)
        if ("".equals(input))
