+Y.H.さんへの返信
+このサンプルプログラムを実行した場合、'a'から'z'まで指定キロバイトまで延々と出力されたテキストファイルができるわけなのですが、例えばテキストファイルの中身を1とだけ入れたい場合は、
+```java
+コード
+     byte[] buffer = new byte[bufferSize];
+        for (int i = 0; i < buffer.length; i++) {
+            buffer[i] = (byte)('a' + i % alphabetRange);
+        }
+```
+のbuffer[i] = (byte)(このぶぶんを変更);
+すればよいのでしょうか？
