Description

The list of methods to do FileOutputStream Write Byte Array are organized into topic(s).

Method

FileOutputStreamwriteBytes(int[] data, String filename)
Writes data from the integer array to disk as raw bytes, overwriting the old file if present. 
FileOutputStream out = new FileOutputStream(filename, false);
writeBytes(data, out);
return out;
voidwriteBytes(int[] data, String filename)
Writes data from the integer array to disk as raw bytes. 
FileOutputStream out = new FileOutputStream(filename);
byte[] b = new byte[4];
for (int word : data) {
    for (int i = 0; i < 4; i++) {
        int offset = (b.length - 1 - i) * 8;
        b[i] = (byte) ((word >>> offset) & 0xFF);
    out.write(b);
...
voidwriteBytes(String filename, byte[] bytes)
write Bytes 
FileOutputStream output = new FileOutputStream(filename);
output.write(bytes);
output.close();
voidwriteBytes(String filename, byte[] data, int len)
write Bytes 
if (filename == null || filename.isEmpty()) {
    return;
try (FileOutputStream out = new FileOutputStream(filename)) {
    out.write(data, 0, len);
voidwriteBytes(String filePath, boolean append, byte[] content)
write Bytes 
FileOutputStream fos = new FileOutputStream(filePath, append);
try {
    fos.write(content);
    fos.flush();
} finally {
    fos.close();
voidwriteBytesInFile(File f, String data)
write Bytes In File 
writeBytesInFile(f, data.getBytes());
voidwriteBytesSafely(File aFile, byte theBytes[])
Writes the given bytes (within the specified range) to the given file, with an option for doing it "safely". 
if (theBytes == null) {
    aFile.delete();
    return;
if (!aFile.exists()) {
    writeBytes(aFile, theBytes);
    return;
File bfile = new File(aFile.getPath() + ".rmbak");
copyFile(aFile, bfile);
writeBytes(aFile, theBytes);
bfile.delete();
FilewriteBytesToFile(byte[] bfile, String filePath, String fileName)
write Bytes To File 
BufferedOutputStream bos = null;
FileOutputStream fos = null;
File file = null;
try {
    file = new File(filePath + "/" + fileName);
    fos = new FileOutputStream(file);
    bos = new BufferedOutputStream(fos);
    bos.write(bfile);
...
voidwriteBytesToFile(byte[] byteContent, String fileName)
* Output Bytes to file ******************************************. 
File kekFile = new File("c:\\temp\\" + fileName);
FileOutputStream f = new FileOutputStream(kekFile);
f.write(byteContent);
f.close();
voidwriteBytesToFile(byte[] bytes, File file)
write Bytes To File 
try {
    FileOutputStream out = new FileOutputStream(file);
    out.write(bytes);
    out.close();
} catch (IOException e) {
    e.printStackTrace();
