Example 1

import java.io.ByteArrayOutputStream;
import java.io.IOException;
public class JavaByteArrayOutputStreamCloseExample1 {
   public static void main(String[] args) throws IOException {
      byte[] close = {65,66,64,67};
      ByteArrayOutputStream baos = new ByteArrayOutputStream();
       baos.close();
         baos.write(close);
         System.out.print(baos);
       }
}
