当有重复的key时，如何创建key value map？

import java.util.HashMap;
import java.util.Map;

public class Main {
    public static void main(String[] args) {
        Map<String, String> map = new HashMap<>();
        map.put("key1", "value1");
        map.put("key2", "value2");
        map.put("key1", "value3"); // 重复的key，后面的value会覆盖前面的value
        System.out.println(map.get("key1")); // 输出：value3
    }
}

map = {"key1": "value1", "key2": "value2", "key1": "value3"} # 重复的key，后面的value会覆盖前面的value
print(map["key1"]) # 输出：value3

let map = {
  "key1": "value1",
  "key2": "value2",
  "key1": "value3" // 重复的key，后面的value会覆盖前面的value
};
console.log(map["key1"]); // 输出：value3
