java - cmd 一直告诉我错误找不到符号

Question

我已经尝试了几天来运行这个，但由于某种原因它没有成功。这是代码:强文本

public class namegenerator {
    public static void main(string[] args) {

    string[] firstnames = {"James", "Philip", "Danny", "Bob", "joshua"};

    string[] lastnames = {"Franklin", "Hunter", "Johnson", "Smith", "Jones"};

    int onelength = firstnames.length;
    int twolength = lastnames.length;

    int rand1 = (int) (Math.random() * onelength);
    int rand2 = (int) (Math.random() * twolength);

    String phrase = firstname [rand1] + " " + lastname [rand2];

    System.out.println("Your fake name is, " + phrase);

    }

}

Answer 1

你有两个错误。

字符串带有“S”，而不是“s”

并且在您的Stringphrase=中，您没有将“s”添加到“firstname”

public static void main(String[] args) {

    String[] firstnames = {"James", "Philip", "Danny", "Bob", "joshua"};

    String[] lastnames = {"Franklin", "Hunter", "Johnson", "Smith", "Jones"};

    int onelength = firstnames.length;
    int twolength = lastnames.length;

    int rand1 = (int) (Math.random() * onelength);
    int rand2 = (int) (Math.random() * twolength);

    String phrase = firstnames[rand1] + " " + lastnames[rand2];

    System.out.println("Your fake name is, " + phrase);

}
