Reads bytes, blocking until all bytes are read.

Usage

From source file:Main.java

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

    String s = "Hello World from java2s.com";

    FileOutputStream out = new FileOutputStream("test.txt");
    ObjectOutputStream oout = new ObjectOutputStream(out);

    // write something in the file
    oout.writeUTF(s);/* w w w . jav  a 2s. co m*/
    oout.flush();
    oout.close();
    // create an ObjectInputStream for the file we created before
    ObjectInputStream ois = new ObjectInputStream(new FileInputStream("test.txt"));

    // read and print from index 0 to 7
    byte[] b = new byte[13];
    ois.readFully(b, 0, 7);
    String array = new String(b);
    System.out.println(array);
    ois.close();
