Java-仅使用一个私有关键字定义私有字段 [英] Java - define private fields using only one private keyword

问题描述

我是否可以仅使用一个 private 关键字来定义私有字段?我真正要问的是:是否有可以做的事情像这样:

Is there a way for me to define private fields using only one private keyword? What I'm really asking is: is there something that I can do that looks like this:

private {
    int x;
    int y;
    Object myObject;
    //etcetera
};

和 x ， y 和 myObject 将全部创建为私有字段

and x, y, and myObject will all be created as private fields

推荐答案

至少在Java中，您不能那样做.因为在Java

At least in java you can't do it like that. Because in java

变量有几种:

1. 类中的成员变量-这些称为字段.
2. 方法或代码块中的变量，这些变量称为局部变量.
3. 方法声明中的变量，这些变量称为参数.

每个变量都有自己的访问修饰符，例如:

And each variables has its own Access Modifiers Like:

1. public 修饰符-该字段可从所有类访问.
2. private 修饰符-该字段只能在其自己的类中访问.

1. public modifier—the field is accessible from all classes.
2. private modifier—the field is accessible only within its own class.

因此，您必须执行以下操作:

So you have to do like following:

private int x,y;
private Object myObject;
