This would mean that the class was initialized, but the variables were not set.

A sample Class:

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;
    }
}

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