Java - define private fields using only one private keyword

问题

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
};

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

回答1:

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

There are several kinds of variables:

1. Member variables in a class—these are called fields.
2. Variables in a method or block of code—these are called local variables.
3. Variables in method declarations—these are called parameters.

And each variables has its own Access Modifiers Like:

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

So you have to do like following:

private int x,y;
private Object myObject;

回答2:

No. Its not possible to define variables of different datatypes in a single block. Closest is this:

private int x,y;
private Object myObject;
