In the following code shows how to use ObjectOutputStream.writeBoolean(boolean val) method.

import java.io.BufferedInputStream;
import java.io.BufferedOutputStream;
import java.io.FileInputStream;
import java.io.FileOutputStream;
import java.io.ObjectInputStream;
import java.io.ObjectOutputStream;
import java.util.Arrays;
/*from w w  w . j  a va  2  s  . c  om*/
public class Main {
  public static void main(String[] args) throws Exception {

    ObjectOutputStream out = new ObjectOutputStream(new BufferedOutputStream(
        new FileOutputStream("file.data")));
    out.writeBoolean(true);
    out.close();

    ObjectInputStream in = new ObjectInputStream(new BufferedInputStream(
        new FileInputStream("file.data")));

    byte[] byteArray = new byte[10];
    in.read(byteArray);
    System.out.println(Arrays.toString(byteArray));
    in.close();
  }
}

The code above generates the following result.
