Description

The list of methods to do File Read via ByteBuffer are organized into topic(s).

Method

byte[]readFile(String name)
Reads an array of bytes from a file. 
try (RandomAccessFile e = new RandomAccessFile(name, "r")) {
    MappedByteBuffer buf = e.getChannel().map(MapMode.READ_ONLY, 0L, e.length());
    byte[] data;
    if (buf.hasArray()) {
        data = buf.array();
        return data;
    byte[] array = new byte[buf.remaining()];
...
byte[]readFile(String name)
read File 
try {
    RandomAccessFile raf = new RandomAccessFile(name, "r");
    ByteBuffer buf = raf.getChannel().map(FileChannel.MapMode.READ_ONLY, 0, raf.length());
    try {
        if (buf.hasArray()) {
            return buf.array();
        } else {
            byte[] array = new byte[buf.remaining()];
...
StringreadFile(String path)
read File 
return readFile(new File(path));
StringreadFile(String path)
Read file. 
try {
    FileInputStream stream = null;
    try {
        stream = new FileInputStream(new File(path));
        FileChannel fc = stream.getChannel();
        MappedByteBuffer bb = fc.map(FileChannel.MapMode.READ_ONLY, 0, fc.size());
        return Charset.defaultCharset().decode(bb).toString();
    } catch (FileNotFoundException e) {
...
StringreadFile(String path)
Read File into a String. 
FileInputStream stream = new FileInputStream(new File(path));
try {
    FileChannel fc = stream.getChannel();
    MappedByteBuffer bb = fc.map(FileChannel.MapMode.READ_ONLY, 0, fc.size());
    return Charset.defaultCharset().decode(bb).toString();
} finally {
    stream.close();
StringreadFile(String path)
read File 
FileInputStream stream = new FileInputStream(new File(path));
try {
    FileChannel fc = stream.getChannel();
    MappedByteBuffer bb = fc.map(FileChannel.MapMode.READ_ONLY, 0, fc.size());
    return Charset.defaultCharset().decode(bb).toString();
} finally {
    stream.close();
byte[]readFileAsByteArray(File file)
read File As Byte Array 
ByteBuffer bb;
FileChannel fc = null;
try {
    fc = new FileInputStream(file).getChannel();
    bb = ByteBuffer.allocate((int) fc.size());
    fc.read(bb);
} finally {
    if (fc != null)
...
byte[]readFileAsByteArray(String path)
This method reads file as binary data. 
return internalReadFileAsByteArray(path).array();
String[]readFileAsStringArray(File file)
read File As String Array 
return readFileAsString(file).split("\n");
voidreadFileChannelFully(FileChannel fileChannel, byte buf[], int off, int len)
Reads len bytes in a loop using the channel of the stream 
int toRead = len;
ByteBuffer byteBuffer = ByteBuffer.wrap(buf, off, len);
while (toRead > 0) {
    int ret = fileChannel.read(byteBuffer);
    if (ret < 0) {
        throw new IOException("Premeture EOF from inputStream");
    toRead -= ret;
