Question

我正在尝试使用Objects构造一个数组数组。我创建了包含多个变量的Object Block。我写道：

Block[][] block = new Block[4][4];

我插入时出现错误：

block[1][1] = new Block(); // As what I've understood, we still need 
                           // to create the object inside this specific block[][]

错误消息是：

无法找到符号，']'预期和无效的方法声明，需要返回类型

Answer 1

它对我有用

public class testProgram {

    public static void main(String args[]) {
        Block[][] block = new Block[4][4];
        block[1][1] = new Block();
        block[1][1].setName("Block 1 1");
        System.out.println(block[1][1].getName());

        block[1][2] = new Block();
        block[1][2].setName("Block 1 2");
        System.out.println(block[1][2].getName());
    }

    public static class Block {

        private String name;

        public String getName() {
            return name;
        }

        public void setName(String name) {
            this.name = name;
        }
    }
}
