When referencing a private variable, do you need the this.variableName declaration?
<pre><code>public class sample {
    private int x = 3;
    public sample() {}
    public sample(int num) {
        this();
        x = num;
    }

    public int getX() {
        // should I use return this.x; or just return x;? Does it matter which one?
    }
}
</code></pre>

<p>I've used the return x; style in my code until now, and I was wondering if using return this.x; provided any benefits, or if it was purely for readability/clarity. My Apologies if this seems vague or confusing, I don't really know how else to word it.</p>
