Question

我需要创建一个名称生成器，它使用for循环和if / else选择来生成名称。对于您输入的四个单词中的每个单词，输入将存储在单独的char []中。

我目前处于迷失状态，到目前为止，我只对下面编码，但它不用于循环或数组。

import java.util.Scanner;

public class NameGenerator
{
    public static void main(String[] args) 
    {

        Scanner input = new Scanner(System.in);

        System.out.printf("Enter your first name: ");

        String firstname = input.nextLine();

        firstname = firstname.substring(0,3);
        System.out.printf("Enter your last name: ");

        String lastname = input.nextLine();
        lastname = lastname.substring(0,2);

        System.out.printf("Enter your mother's maiden name: ");
        String mothersname = input.nextLine();
        mothersname = mothersname.substring(0,2);

        System.out.printf("Enter the name of the city in which you were born: ");
        String cityname = input.nextLine();
        cityname = cityname.substring(0,3);

        String GenFirstName = (firstname  + lastname); 
        String GenLastName = (mothersname + cityname);
        System.out.println("May the force be with you, " + GenFirstName + " " + GenLastName );
    }

}

我不太确定你真正追求的是什么，但这就是我想出来的。

import java.util.Scanner;

public class NameGenerator
{
public static void main(String[] args)
{

    Scanner input = new Scanner(System.in);

    System.out.printf("Enter your first name: ");
    char[] firstname;
        firstname = input.next().toCharArray();

    System.out.printf("Enter your last name: ");
    char[] lastname;
    lastname = input.next().toCharArray();

    System.out.printf("Enter your mother's maiden name: ");
    char[] mothersname;
    mothersname = input.next().toCharArray();

    System.out.printf("Enter the name of the city in which you were born: ");
    char[] cityname;
    cityname = input.next().toCharArray();

    String GenFirstName = "";
    String GenLastName = "";

    for(int count = 0; count <= 3; count++){
        GenFirstName += firstname[count];
        GenLastName += mothersname[count];
    }

    for(int count = 0; count <= 3; count++){
        GenFirstName += lastname[count];
        GenLastName += cityname[count];
    }

    System.out.println("May the force be with you, " + GenFirstName + " " + GenLastName );
}

}

UPDATE 这是命令行参数版本。

    public class NameGenerator
{
public static void main(String[] args)
{

    char[] firstname;
        firstname = args[0].toCharArray();

    char[] lastname;
    lastname = args[1].toCharArray();

    char[] mothersname;
    mothersname = args[2].toCharArray();

    char[] cityname;
    cityname = args[3].toCharArray();

    String GenFirstName = "";
    String GenLastName = "";

    for(int count = 0; count <= 3; count++){
        GenFirstName += firstname[count];
        GenLastName += mothersname[count];
    }

    for(int count = 0; count <= 3; count++){
        GenFirstName += lastname[count];
        GenLastName += cityname[count];
    }

    System.out.println("May the force be with you, " + GenFirstName + " " + GenLastName );
}

}
