实现对象的二维数组

var twoDimensionalArray = [
  { name: "Alice", age: 25 },
  { name: "Bob", age: 30 },
  { name: "Charlie", age: 35 }
];

two_dimensional_array = [
  {"name": "Alice", "age": 25},
  {"name": "Bob", "age": 30},
  {"name": "Charlie", "age": 35}
]

class Person {
  String name;
  int age;
  
  public Person(String name, int age) {
    this.name = name;
    this.age = age;
  }
}

Person[][] twoDimensionalArray = {
  { new Person("Alice", 25), new Person("Bob", 30) },
  { new Person("Charlie", 35), new Person("Dave", 40) }
};
