Java setters and "this"

Question

I noticed that many people do in Java installations:

1)

public void setX(int x) {
    this.x = x;
}

Personally, I don't like this, and I think it should be something like:

2)

public void setX(int newX) {
    x = newX;
}

Are there any reasons for the former to be better?

Not 1) it’s easier to make a mistake. On several occasions, I tracked code errors that people make:

x = x; 

mistakenly, maybe because they typed quickly and just wanted to remove getters and setters.

Answer 1

This is a matter of style. Argument in favor

public void setX(int x) { this.x = x; }

is that you don’t need to think about a new and meaningful name for the input argument, since you already have one.

Choose a style and use it consistently.
