我想知道我是否可以在数组中有一个数组?我想不出解释它的方法。

        if (numOfPlayers >= 2) {
          this.config.getString("Tribute_one_spawn");
          String[] onecoords = this.config.getString("Tribute_one_spawn").split(",");
          Player Tribute_one = (Player)this.Playing.get(0);
          World w = p.getWorld();
          double x = Double.parseDouble(onecoords[0]);
          double y = Double.parseDouble(onecoords[1]);
          double z = Double.parseDouble(onecoords[2]);
          Location oneloc = new Location(w, x, y, z);
          Tribute_one.teleport(oneloc);
          this.Frozen.add(Tribute_one);
          Tribute_one.setFoodLevel(20);
          this.config.getString("Tribute_two_spawn");
          String[] twocoords = this.config.getString("Tribute_two_spawn").split(",");
          Player Tribute_two = (Player)this.Playing.get(1);
          World twow = p.getWorld();
          double twox = Double.parseDouble(twocoords[0]);
          double twoy = Double.parseDouble(twocoords[1]);
          double twoz = Double.parseDouble(twocoords[2]);
          Location twoloc = new Location(twow, twox, twoy, twoz);
          Tribute_two.teleport(twoloc);
          this.Frozen.add(Tribute_two);
          Tribute_two.setFoodLevel(20);
        }
        if (numOfPlayers() >= 3) {
          this.config.getString("Tribute_three_spawn");
          String[] coords = this.config.getString("Tribute_three_spawn").split(",");
          Player Tribute_three = (Player)this.Playing.get(2);
          World w = p.getWorld();
          double x = Double.parseDouble(coords[0]);
          double y = Double.parseDouble(coords[1]);
          double z = Double.parseDouble(coords[2]);
          Location loc = new Location(w, x, y, z);
          Tribute_three.teleport(loc);
          this.Frozen.add(Tribute_three);
          Tribute_three.setFoodLevel(20);
        }

正如您所看到的,我必须在每个玩家的if else梯形图中创建一个新数组。有没有一种方法可以改变coords数组的变量名称,将其置于for循环中,并使用计数器递增数组名称。那是解释它的一种令人困惑的方式,但这是我能做的最好的事情。

简短的回答是肯定的,您可以声明一个类似String[][] playerCoords的数组,但是我建议您查看Map界面,因为它可能更能描述您想要做什么。

答案 1 :(得分:1)

我不太确定我是否理解正确,但您可能想要做一些像二维数组的事情。看看这里:

它是这样分配的:

double[][] a2 = new double[10][5];

只要您可以重命名配置变量,就可以将代码换成for循环:

for (int i=1;i<numOfPlayers;i++) {
          String[] onecoords = this.config.getString().split(",");
          Player Tribute_i = (Player)this.Playing.get(i-1);
          World w = p.getWorld();
          double x = Double.parseDouble(onecoords[0]);
          double y = Double.parseDouble(onecoords[1]);
          double z = Double.parseDouble(onecoords[2]);
          Location oneloc = new Location(w, x, y, z);
          Tribute_i.teleport(oneloc);
          this.Frozen.add(Tribute_i);
          Tribute_i.setFoodLevel(20);
}

Yor配置变量将被命名为Tribute_1_spawn,Tribute_2_spawn等等...... 如果需要进一步使用Player对象,可以将它们保存在数组或其他数据结构中。
