私は学校授業の一環としてアドレス帳をやっていますが、私はそれを大部分は理解していますが、私は一部に固執しています。ここに私のコードがあります。私は変数を含むAddressBookクラスを持っていて、本の中の各人物の情報を変更/返すための適切なgetterメソッドとsetterメソッドを持っています。次に、アドレス帳の仕組みを示すメソッドmainを持つTestAddressBookクラスがあります。私が立ち往生している唯一のことは、最終的な要件です。ここでは、2つの名前を比較し、それらが等しいかどうかを確認して結果を表示するよう求められます。プログラムを私が望むように設計しましたが、何らかの理由で比較を行うと、比較結果が表示されません。ただ何も印刷しません。私は明らかな何かを見逃すはずです。ここにクラスのコードがあります。アドレス帳プログラム

また、私のAddressBookクラスのcompareNamesメソッドは何も印刷しないと明示的に指示しているだけで、比較の値を返します。だから私は私のテストクラスのメソッド呼び出しからそれを印刷する必要があります。つまり、「名前1と名前1が等しい名前ではない」のようなものです – ripp2k
あなたはあなたのコードに 'compareNames'の結果を出力しようとしていません。 – UnholySheep
テストクラスで名前比較の結果を印刷するにはどうすればいいですか？ – ripp2k
