FileOutputStream is a Java class used to write bytes directly to a File or to a FileDescriptor.
FileOutputStream is a Java class used to write bytes directly to a File or to a FileDescriptor.
Whether or not a file is available or may be created depends upon the underlying platform. Some platforms, in particular, allow a file to be opened for writing by only one FileOutputStream (or other file-writing object) at a time. In such situations the constructors in this class will fail if the file involved is already open.
FileOutputStream is meant for writing streams of raw bytes such as image data. For writing streams of characters, consider using FileWriter.
