java如何将字符串数组调用到方法中

Question

我定义了3个方法，其中字符串[]作为参数。我想从另一个函数中设置这些函数，使用一些字符串，然后打印每个函数

当我尝试从另一个函数（start（）函数）调用这些方法时，要设置String[]参数的值，Eclipse会说：

类型不匹配：无法从字符串转换 串

public class logistics2 {

private static String plane;
private static String truck;
private static String airport[];
private static String loc[];
private static String city[];
private static String pack[];


public static void at_obj_place(String object, String[] place) {

    object = truck;
    object = plane;
    place = loc;
    place = city;
    place = airport;

    return;
}

public static void in_pk_vehicle(String[] Pack, String vehicle) {

    Pack = pack;
    vehicle = truck;
    vehicle = plane;

    return;

}

public static void in_city(String[] place, String[] City ) {

    place = loc;
    City = city;

    return;
}





public static void start() {

    // HERE I RECEIVE THE ERROR MESSAGE
    in_city(airport = "cdg", city = "paris");
    in_city(airport = "lhr", city = "london");
    in_city(loc = "north", city = "paris");
    in_city(loc = "south",city = "paris");

    at_obj_place(plane = "plane", airport = "lhr");
    at_obj_place(truck = "truck", airport =  "cdg");
    at_obj_place(pack1 = "p1", airport = "lhr");
    at_obj_place(pack2 = "p2", airport = "lhr");


    for(int i = 0; i < airport[].length(); ) {

        System.out.println(airport + " " + city);
    }



    return;

我想根据我在字符串[]中插入的数值的计数，打印我用for条件设置的每个数值

Answer 1

在所有必须传递字符串的方法中，必须传递字符串数组。对于所有阵列，都是这样：

airport[0] = "cdg";
airport[1] = "lhr";
city[0] = "paris";
city[1] = "london";

然后将其传递给以下方法：

in_city(airport,city);

在for循环中，只需提到数组名，比如airport而不是airport[]，并为i添加增量
