在ArrayList中存储二维网格中对象的坐标和特征

public class CoordinateFeature {
    private int x;
    private int y;
    private String feature;

    public CoordinateFeature(int x, int y, String feature) {
        this.x = x;
        this.y = y;
        this.feature = feature;
    }

    // 省略getter和setter方法
}

import java.util.ArrayList;

public class Main {
    public static void main(String[] args) {
        ArrayList<CoordinateFeature> grid = new ArrayList<>();

        // 添加对象到ArrayList
        grid.add(new CoordinateFeature(0, 0, "A"));
        grid.add(new CoordinateFeature(1, 0, "B"));
        grid.add(new CoordinateFeature(0, 1, "C"));

        // 遍历ArrayList并打印坐标和特征
        for (CoordinateFeature cf : grid) {
            System.out.println("坐标: (" + cf.getX() + ", " + cf.getY() + "), 特征: " + cf.getFeature());
        }
    }
}
