注册Codewars Java练习2

我刚刚试着注册，目前正在进行练习二，试图找出答案。这里是代码

public class Person {
    String name;

    public Person(String personName) {
        name = personName;
    }

    public String greet(String yourName) {
        return String.format("Hi %s, my name is %s", name, yourName);
    }
}

这些是我做的改变，在当时似乎是有意义的，但我仍在通过它来找到什么是有效的

public class Person {
    String name;

    public Person(String personName) 
    {
        name = "John";
    }

    public String greet(String "Tommy");
    {
        return String.format("Hi %s, my name is %s", name, yourName);
    }
}

如果我将它粘贴到Eclipse中并从那里运行它，它是否会作弊

我希望这是足够清楚，如果有任何方法，我可以改善这篇文章或使任何更清楚，请让我知道：）谢谢

下面代码中的更正和注释。如果你学习了语言的一些基础知识，你就会理解一切，否则会很有趣

public class Person {
    String name;

    //This is a constructor and invoked during creation of object
    public Person(String personName) 
    {
            //makes no sense to pass personName to construct but, not use it
            //name = "John";
            name = personName; 
    }

    //A method signature does not end with semi-colon
    //You cannot pass string literal in function as argument, "Tommy" incorrect arg
    //public String greet(String "Tommy");
    public String greet(String greeting)
    {
            //not sure where you come up with yourName but, i replaced with greeting arg
            return String.format("Hi %s, my name is %s", name, greeting);
    }

    //add main to show you how this works, when run execution enters main first
    public static void main(String[] args) {

        //an object of Person class is created passing "John" to its constructor      
        Person p  = new Person("John"); 

        //p.greet() invokes the greet method of Person object
        System.out.println(p.greet("Oops!")); 
    }
}

您只需要在String.format（）函数中交换name和yourName，请参见下面的代码

return String.format("Hi %s, my name is %s", yourName, name);

复制/粘贴而不理解是欺骗。代码中有大量错误，我建议您阅读Java基础知识。我可以用更正来回答你，但我不确定这对你有什么帮助，除非你从Java的基础知识开始。OP在另一个网站参加了一个编码游戏，并询问了另一个网站的游戏规则。我想你是对的，我真的对东西很生疏，最好还是把注意力集中在基本的东西上。谢谢大家

public class Person {

  String name;

    public Person(String personName) {
      name = personName;
   }

    public String greet(String yourName) {
      return String.format("Hi %s, my name is %s", yourName, name);
    }
}
