Syntax

DataOutputStream.writeBoolean(boolean v) has the following syntax.

public final void writeBoolean(boolean v)   throws IOException

Example

In the following code shows how to use DataOutputStream.writeBoolean(boolean v) method.

/*  www  .j  av a2s  .  co m*/
import java.io.ByteArrayOutputStream;
import java.io.DataOutputStream;
import java.io.IOException;

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

    boolean[] bools = { true, false, false, true, true, true };

    ByteArrayOutputStream baos = new ByteArrayOutputStream();
    DataOutputStream dos = new DataOutputStream(baos);

    for (boolean bool : bools) {
      dos.writeBoolean(bool);
    }

    dos.flush();

    for (byte b : baos.toByteArray()) {
      System.out.print(b);
    }
  }
}
