How to flush output stream after writing bytes
Let us first crate OutputStream with file input.txt −
FileOutputStream fileStream = new FileOutputStream("E:/input.txt");
DataOutputStream dataStream = new DataOutputStream(fileStream);Now, the writeBytes() method writes out the string to the underlying output stream as a sequence of bytes.
dataStream.writeBytes("Demo text!");Flush the output stream −
dataStream.flush();
The following is an example. Here, our file is “E:/input.txt” and at the end we are flushing the output stream −
Example
import java.io.DataOutputStream;
import java.io.FileOutputStream;
public class Demo {
public static void main(String[] args) throws Exception {
FileOutputStream fileStream = new FileOutputStream("E:/input.txt");
DataOutputStream dataStream = new DataOutputStream(fileStream);
dataStream.writeBytes("Demo text!");
dataStream.flush();
dataStream.close();
}
}The output is as follows i.e. the text in the file is −
Output
Demo text!
