তারপর, আপনি পুরোনো প্রোগ্রামারের বন্ধু, এডিটর অটোকমপ্লিশনের সাহায্যে নেওয়ার চেষ্টা করেন।

আপনি ফাংশনের প্রথম প্যারামিটার `first_name` টাইপ করেন, তারপর একটি ডট (`.`) টাইপ করেন এবং `Ctrl+Space` চাপেন অটোকমপ্লিশন ট্রিগার করার জন্য।

কিন্তু, দুর্ভাগ্যবশত, আপনি কিছুই উপযোগী পান না:

### টাইপ যোগ করুন

আসুন আগের সংস্করণ থেকে একটি লাইন পরিবর্তন করি।

    assertEquals(0, (int) ictim.getInstance(Integer.class));
    assertEquals(1, (int) ictim.getInstance(int.class));
  }

  @SuppressWarnings("rawtypes") // TODO(cpovirk): Can we at least use Class<?> in some places?
  abstract static class TestClassToInstanceMapGenerator implements TestMapGenerator<Class, Impl> {

    @Override
    public Class<?>[] createKeyArray(int length) {
      return new Class<?>[length];
    }

 * @since 2.0
 */
@GwtCompatible
public abstract class ForwardingMapEntry<K extends @Nullable Object, V extends @Nullable Object>
    extends ForwardingObject implements Map.Entry<K, V> {
  // TODO(lowasser): identify places where thread safety is actually lost

  /** Constructor for use by subclasses. */
  protected ForwardingMapEntry() {}

  @Override
  protected abstract Entry<K, V> delegate();

  @Override

آیا اسمش `upper` بود؟ یا `uppercase`؟ شاید `first_uppercase`؟ یا `capitalize`؟

بعد، با دوست قدیمی برنامه‌نویسا، تکمیل خودکار ویرایشگر، امتحان می‌کنی.

پارامتر اول تابع، `first_name` رو تایپ می‌کنی، بعد یه نقطه (`.`) می‌ذاری و `Ctrl+Space` رو می‌زنی تا تکمیل خودکار بیاد.

ولی متأسفانه، چیز مفیدی نمی‌گیری:

### نوع اضافه کن

بیا فقط یه خط از نسخه قبلی رو تغییر بدیم.

  /**
   * Closed addressing tends to perform well even with high load factors. Being conservative here
   * ensures that the table is still likely to be relatively sparse (hence it misses fast) while
   * saving space.
   */
  @VisibleForTesting static final double MAX_LOAD_FACTOR = 1.2;

  /**
   * Maximum allowed false positive probability of detecting a hash flooding attack given random
   * input.
   */

Sau đó, bạn thử hỏi người bạn cũ của mình, autocompletion của trình soạn thảo.

Bạn gõ tham số đầu tiên của hàm, `first_name`, sau đó một dấu chấm (`.`) và sau đó ấn `Ctrl+Space` để kích hoạt bộ hoàn thành.

Nhưng đáng buồn, bạn không nhận được điều gì hữu ích cả:

### Thêm kiểu dữ liệu

Hãy sửa một dòng từ phiên bản trước.

#
#   (2) This script targets any POSIX shell, so it avoids extensions provided
#       by Bash, Ksh, etc; in particular arrays are avoided.
#
#       The "traditional" practice of packing multiple parameters into a
#       space-separated string is a well documented source of bugs and security
#       problems, so this is (mostly) avoided, by progressively accumulating
#       options in "$@", and eventually passing that to Java.
#

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:
