A subset of the OutputStream hierarchy
-
OutputStream <<abstract>>
-
FileOutputStream
-
FilterOutputStream
- BufferedOutputStream
-
DataOutputStream <<implements DataOutput interfaces>>
-
Classes used to connect a binary output stream to a file
-
DataOutputStream – writes data to the stream
-
BufferedOutputStream – creates a buffer for the stream
-
FileOutputStream – connects the stream to a file
-
-
Constructors of these classes:
| Constructors | Throws |
| DataOutputStream(OutputStream) | none |
| BufferedOutputStream(OutputStream) | none |
| FilterOutputStream(File [,booleanAppend]) | IOException |
| FilterOutputStream(StringFileName [ , booleanAppend]) | IOException |
Example 1: A File object that refers to a binary file
File productsFile = new File("products.dat")Example 2: How to connect to a file with a buffer
DataOutputStream out = new DataOutputStream( new BufferedOutputStream( new FilterOutputStream(productsFile)));Example 3: How to connect for an append operation
DataOutputStream out = new DataOutputStream( new BufferedOutputStream( new FilterOutputStream(productsFile, true)));Descriptions:
- All classes in java.io and java.util.zip packages that end with OutputStream are members of the OutputStream hierarchy.
Warning:
- By default, the output file is overwritten.
