The toByteArray() method of Java ByteArrayOutputStream class is used to create a newly allocated byte array with the size as the current size of this output stream.

Syntax:

Returns

The toByteArray() method returns the current contents of this output stream as a byte array.

Example 1

import java.io.ByteArrayOutputStream;
import java.io.IOException;
public class JavaByteArrayOutputStreamToByteArrayExample1 {
    public static void main(String[] args) throws IOException {
        byte[] bs = {65, 66, 67, 68, 69};
        ByteArrayOutputStream baos = null;
        baos = new ByteArrayOutputStream();
        baos.write(bs);
        for (byte b : baos.toByteArray()) {
            baos.write(b);
            System.out.println(b);
        }
    }
