Java - 对二维数组进行排序

Question

我试图让此代码循环遍历嵌套字符串/数组并根据给定的输入值输出值。

        // wepName - {"Weapon Name Here", "Player Damage", "Block Damage", "Range"}
    String[] weapon_44Magnum = {"44 Magnum", "150", "50", "45"};
    String[] weapon_airFilterLandMine = {"Air Filter Land Mine", "300", "200", "5"};
    String[] weapon_huntingRifle = {"Hunting Rifle", "125", "50", "100"};


    //Nested string arrays
    public String[] string_allWeapons[] = {weapon_44Magnum,weapon_airFilterLandMine,weapon_huntingRifle};



public String GetPlayerDamage(String weaponName) {

    // Declaring var
    String ret = "-1";

        for (int j = 0; j < string_allWeapons[0].length; j++) {

            ret = string_allWeapons[j][1] = ret;
            System.out.println(string_allWeapons[j][1]);
        }
    return ret;
}

有什么解决办法吗？

您可以添加一个 if 来检查参数需要哪个数组，然后添加第二个循环。

public class Stuff {
    // wepName - {"Weapon Name Here", "Player Damage", "Block Damage", "Range"}
    String[] weapon_44Magnum = {"44 Magnum", "150", "50", "45"};
    String[] weapon_airFilterLandMine = {"Air Filter Land Mine", "300", "200", "5"};
    String[] weapon_huntingRifle = {"Hunting Rifle", "125", "50", "100"};

    //Nested string arrays
    String[][] string_allWeapons = {weapon_44Magnum,weapon_airFilterLandMine,weapon_huntingRifle};

    public static void main(String[] args) {
        new Stuff().getPlayerDamage("44 Magnum");
    }
    public  String getPlayerDamage(String weaponName) {
        String ret = "-1";
        for (int i = 0; i < string_allWeapons.length; i++) {
            if(string_allWeapons[i][0].equals(weaponName)){
                ret="";
                for (int j = 1; j < string_allWeapons[i].length; j++) {
                    ret += " "+string_allWeapons[i][j];
                }
                System.out.println(ret);
                return ret;
            }
        }
        return ret;
    }
}
