Flushes this output stream and forces any buffered output bytes to be written out.

Usage

From source file:Main.java

public static void main(String[] args) throws IOException {

    byte b = 66;//  w ww. j a  va2  s.  c o  m
    int i = 0;
    FileOutputStream fos = new FileOutputStream("C://test.txt");

    fos.write(b);

    fos.flush();

    FileInputStream fis = new FileInputStream("C://test.txt");

    // read till the end of the file
    while ((i = fis.read()) != -1) {
        // convert integer to character
        char c = (char) i;

        System.out.print(c);
    }

}

From source file:Main.java
