以下のサンプルコードでは、thisを使ってオブジェクト自身を返すメソッドを示しています。
このように、thisはオブジェクト自身を参照するための重要なキーワードであり、コードの可読性や意図を明確にするのに役立ちます。
This refers back to the object you’re “in” right this moment. To put it differently,this refers back to the acquiring object. You employ this to make clear which variable you’re referring to.Java_whitepaper page :37

Exact success, but without possibility of a bug in which you unintentionally seek advice from x when you really intended to be referring to x as a substitute.
Offical java documentation page on this supplies identical use-scenarios. Within just an occasion approach or perhaps a constructor, this is really a reference to The existing object — the item whose technique or constructor is remaining named.
This system compiles, though the occasion variable won't ever be initialised in the constructor. It will always be 0 - from your default constructor.
