我可以从字符串开始并实例化该字符串的对象吗？

class StringObject:
    def __init__(self, string):
        self.string = string

string = "Hello, world!"
string_object = StringObject(string)
print(string_object.string)

public class StringObject {
    private String string;

    public StringObject(String string) {
        this.string = string;
    }

    public String getString() {
        return string;
    }

    public static void main(String[] args) {
        String string = "Hello, world!";
        StringObject stringObject = new StringObject(string);
        System.out.println(stringObject.getString());
    }
}

class StringObject {
    constructor(string) {
        this.string = string;
    }
}

const string = "Hello, world!";
const stringObject = new StringObject(string);
console.log(stringObject.string);
