しかし、そうすると「最初の文字を大文字に変換するあのメソッド」を呼び出す必要があります。

それは`upper`でしたか？`uppercase`でしたか？それとも`first_uppercase`？または`capitalize`？

そして、古くからプログラマーの友人であるエディタで自動補完を試してみます。

関数の最初のパラメータ`first_name`を入力し、ドット(`.`)を入力してから、`Ctrl+Space`を押すと補完が実行されます。

しかし、悲しいことに、これはなんの役にも立ちません:

### 型の追加

先ほどのコードから一行変更してみましょう。

以下の関数のパラメータ部分を:

```Python

        assertEquals("test{}|\\", result);

        result = systemHelper.encodeUrlFilter("test^path");
        assertEquals("test^path", result);

        result = systemHelper.encodeUrlFilter("test space");
        assertEquals("test+space", result);
    }

    public void test_normalizeLang_caseVariations() {
        assertEquals("ja", systemHelper.normalizeLang("JA"));
        assertEquals("ja", systemHelper.normalizeLang("Ja"));

    /**
     * A map of field rules.
     */
    protected Map<String, String> fieldRuleMap = new LinkedHashMap<>();

    /** a flag to trim a space characters. */
    protected boolean trimSpaceEnabled = true;

    /**
     * The charset name.
     */
    protected String charsetName = Constants.UTF_8;

    /**

        byte[] fileNameBytes = fileName.getBytes(StandardCharsets.UTF_16LE);
        int totalSize = 12 + fileNameBytes.length + 50; // Extra space for safety
        byte[] buffer = new byte[totalSize];

        // Write next entry offset (4 bytes)
        SMBUtil.writeInt4(nextOffset, buffer, 0);

        // Write action (4 bytes)
