Inner的toString會被調(diào)用,這是肯定的.
你的 final int finalLocalVar = 6; 可以加個static,這樣可以節(jié)省一定的內(nèi)存和CPU開銷. 不過好像沒有用到么,那就刪除吧.

同意樓上的
Object obj = outer.makeTheInner( 47 );
System.out.println( "The object is " + obj );
這時其實是System.out.println( "The object is " + obj.toString());

Object obj = outer.makeTheInner( 47 );
等同與
Object obj =new Inner();/////////示意一下
toString方法已經(jīng)在Inner類中被重寫了
所以輸出應該是The object is localvar=47>
