在Java中将用户输入解释为变量名？

Question

所以,我正在尝试继续我的长颈鹿计划(不要问).我希望用户为他们的长颈鹿命名,这应该是长颈鹿的名字.例如:

System.out.println("Name your giraffe.");

就像是:

Giraffes.somenewvariabletype scannerexample.nextLine() = Giraffes.Giraffe(parameter, parameter)

Answer 1

也许你想要这样的东西

public class Giraffe{
    String name;

    public Giraffe(String name){
        this.name = name;          // this set the name for your Giraffe object
    }

    public getName(){     // returns the name of the Giraffe object
        return name;
    }
}

然后你可以像这样使用它

Scanner scanner = new Scanner(System.in);
System.out.println("Name your giraffe.");
String name = scanner.nextLine();     // get user input for name

Giraffe giraffe = new Giraffe(name);  // use the constructor above to set name

System.out.println(giraffe.getName());  // prints name of giraffe
