ユーザー入力によって設定された列挙型の値を返すことができるメソッドを作成しようとしています。列挙型をデカールしてから、ユーザーの入力によって列挙型を設定しようとしました。GetPlayerClass メソッドを使用して Player_Class の値を返すことができません。これが列挙型を使用して値を設定する正しい方法であるかどうか、またはユーザーが列挙型リストから選択して選択できるようにする方法があるかどうかを教えてください。
私のコードは以下です。
TLDR: 私は「列挙型」で、列挙型から変数の値を設定し、後でその値を返す方法を理解できません。私のコードを見て、私が間違っていることを教えてください。
// The PCs base class
private enum Base_Class {
Barbarian, Bard, Cleric, Druid, Fighter, Monk,
Paladin, Ranger, Rogue, Sorcerer, Wizard
};
// Setting the base class
public void setBaseClass() {
do {
System.out.println("Available Classes: ");
System.out.println("Please select a cooresponding number for class.");
int i = 1;
for(Base_Class value: Base_Class.values()){
System.out.println(i+": "+value.name());
i++;
}
try {
Base_Class_Choice = user_input.nextInt();
switch(Base_Class_Choice) {
case 1:
Base_Class Player_Class;
Player_Class = Base_Class.Barbarian;
break;
case 2:
break;
default:
break;
}
} catch (Exception e) {
System.out.println("You must choose a valid class. Try numbers.");
user_input.next();
}
} while (Base_Class_Choice == 0);
}
/**
* Return my players class
* @return
*/
public String getPlayerClass() {
return Player_Class;
}
以下のコードを更新しました。私の試行領域は次のようになりました。
try {
Base_Class_Choice = user_input.nextInt();
Base_Class Player_Class = Base_Class.values()[Base_Class_Choice - 1];
} catch (Exception e) {
System.out.println("You must choose a valid class. Try numbers.");
user_input.next();
}
しかし、Base_Class Player_Class のリターンは機能しません。
public String getPlayerClass() {
return Player_Class;
}
Player_Class を返そうとしても、シンボルが見つからないというエラーで失敗します。私はまだ何が間違っているのでしょうか？
アップデート！！！！「すべてのコード!!!」
