Scenario 3: Making use of this to get in touch with alternate constructors. In the reviews, trinithis accurately pointed out Yet another common usage of this.
以下のサンプルコードは、静的メソッド内でthisを使用しようとした場合のエラーを示しています。
14 @Hazior: I tend to jot down a short answer after which you can insert to it with time. Sometimes that overlaps with other people's solutions, often not. In the case of my hottest edit, trinithis identified A further popular utilization of this that I forgot, so I additional it to my reply.
初めにthisの意味と使い方を解説します。thisは同じ変数名やメソッド名があるときに、それらを区別するために使用します。

resulting code of both of those procedures will be the exact. The real difference will probably be if some method declares community variable With all the same identify
