Examples of java.io.FileOutputStream

java.io.FileOutputStream
FileOutputStream is a class whose underlying stream is represented by a file in the operating system. The bytes that are written to this stream are passed directly to the underlying operating system equivalent function. Since overhead may be high in writing to the OS, FileOutputStreams are usually wrapped with a BufferedOutputStream to reduce the number of times the OS is called.
BufferedOutputStream buf = new BufferedOutputStream(new FileOutputStream("aFile.txt")); @see FileInputStream

        BlobType bv = new BlobType(blob);
        String key = bv.getReferenceStreamId();
        
        // now force to serialize
        File saved = new File(UnitTestUtil.getTestScratchPath()+"/blobassaved.bin"); //$NON-NLS-1$
        ObjectOutputStream out = new ObjectOutputStream(new FileOutputStream(saved));
        out.writeObject(bv);
        out.close();
        
        // now read back the object from serilized state
        ObjectInputStream in = new ObjectInputStream(new FileInputStream(saved));
