如何将所有类型从接口更改为字符串？

let num = 10;
let str = num.toString(); // 将数字转换为字符串

let bool = true;
let str2 = bool.toString(); // 将布尔值转换为字符串

let arr = [1, 2, 3];
let str3 = arr.toString(); // 将数组转换为逗号分隔的字符串

let obj = { name: "John", age: 25 };
let str4 = JSON.stringify(obj); // 将对象转换为JSON字符串

num = 10
str = str(num)  # 将数字转换为字符串

bool = True
str2 = str(bool)  # 将布尔值转换为字符串

arr = [1, 2, 3]
str3 = str(arr)  # 将数组转换为字符串

obj = {"name": "John", "age": 25}
str4 = str(obj)  # 将字典转换为字符串

int num = 10;
String str = String.valueOf(num);  // 将整数转换为字符串

boolean bool = true;
String str2 = String.valueOf(bool);  // 将布尔值转换为字符串

int[] arr = {1, 2, 3};
String str3 = Arrays.toString(arr);  // 将数组转换为字符串

Map<String, Object> obj = new HashMap<>();
obj.put("name", "John");
obj.put("age", 25);
String str4 = obj.toString();  // 将Map转换为字符串
