使用保留包名访问包 - 私有变量

class MyClass:
    def __init__(self):
        self.__private_var = "This is a private variable"

    def get_private_var(self):
        return self.__private_var

public class MyClass {
    private String privateVar = "This is a private variable";

    public String getPrivateVar() {
        return privateVar;
    }
}

const privateVar = Symbol("This is a private variable");

class MyClass {
    constructor() {
        this[privateVar] = "This is a private variable";
    }

    getPrivateVar() {
        return this[privateVar];
    }
}
