Question

让我们开始做生意吧。我有这行代码：

    public static Tile[] tiles = new Tile[400];

在eclipse中给出了以下错误

    Syntax error on token ";", { expected after this token

Tile是同一个项目和程序包中的一个类，我想创建一个数组，因为我无法想到在程序的其余部分做任何其他事情......

我已经看过google和stackoverflow，但无法找到答案。有人可以向我解释我做错了吗？

提前致谢，德克。

编辑：这是Tile类：

    package com.mrdls.invade;

    public class Tile {

        public String name = "";
        public int id = 0;
        public boolean passable = false;

        public Tile(String name, int id){
            this.name = name;
            this.id = id;

            if(name == "air"){
                passable = true;
            }
        }
    }

EDIT2，这是TilesBlocks类

    package com.mrdls.invade;

    import java.awt.image.BufferedImage;

    import javax.imageio.ImageIO;

    public class TilesBlocks {

        public static BufferedImage tilesetBlocks;

        public static int pixelsPerTile = 20;

        public int[] ints = new int[20];

        public Tile[] tiles = new Tile[400];

        tiles[0] = new Tile("air", -1);
        /*public static final Tile earth = new Tile("earth", 0);
        public static final Tile stone = new Tile("stone", 1);
        public static final Tile cobblestone = new Tile("cobblestone", 2);
        public static final Tile sand = new Tile("sand", 3);
            public static final Tile sandstone = new Tile("sandstone", 4);
        public static final Tile grass = new Tile("grass", 5);
        public static final Tile woodLog = new Tile("log", 6);
        public static final Tile leaves = new Tile("leaves", 7);
        public static final Tile pumpkin = new Tile("pumpkin", 8);
        public static final Tile melon = new Tile("melon", 9);
        public static final Tile pumpkinCarved = new Tile("carved pumpkid", 10);

        public static final Tile copperOre = new Tile("copper ore", 20);
        public static final Tile tinOre = new Tile("tin ore", 21);
        public static final Tile ironOre = new Tile("iron ore", 22);
        public static final Tile silverOre = new Tile("silver ore", 23);
        public static final Tile goldOre = new Tile("gold ore", 24);

        public static final Tile diamondOre = new Tile("diamond ore", 40);
        public static final Tile emeraldOre = new Tile("emerald ore", 41);
        public static final Tile rubyOre = new Tile("ruby ore", 42);
        public static final Tile sapphireOre = new Tile("sapphire ore", 43);*/

        public TilesBlocks(){
            try{
                TilesBlocks.tilesetBlocks = ImageIO.read(Tile.class.getResourceAsStream("/tileset_terrain.png"));
            }catch(Exception e){

            }
        }
    }

Answer 1

        tiles[0] = new Tile("air", -1);

你不能在班上这样做。您需要在构造函数中分配它。阅读初始化和分配之间的区别。

字段的初始化属于方法之外，但当然是由类封装。

作业属于一种方法。

或者你可以这样初始化：

Tiles []tiles = new Tiles[]{new Tile("air",-1)} ;

并使用.equals not ==

Answer 2

这个完整的课程很好。我没有看到你的班级和用法有任何错误。

这是完整的课程

package com.test;

public class Tile {

    public static Tile[] tiles = new Tile[400];

    public String name = "";
    public int id = 0;
    public boolean passable = false;

    public Tile(String name, int id) {
        this.name = name;
        this.id = id;

        if (name.equals("air")) {
            passable = true;
        }
    }
}

Answer 3

单击红色错误消息，很可能您将看到'抑制'或'清除lint标记'Eclipse有时会记录错误（当您键入时）并且不会清除标记。清除Lint Markers并查看错误是否消失

创建对象数组会产生语法错误
