What is the best way to know if all the variables in a Class are null?
<p>This would mean that the class was initialized, but the variables were not set.</p>

<p>A sample Class:</p>

<pre><code>public class User {

    String id = null;
    String name = null;

    public String getId() {
        return id;
    }
    public void setId(String id) {
        this.id = id;
    }

    public String getName() {
        return name;
    }
    public void setName(String name) {
        this.name = name;
    }
}
</code></pre>

<p>The actual class is huge that I prefer not to check if(xyz == null) for each of the variables.</p>
