New to Java

I find this a little tricky and could use some help. Here is what I have so far...

@Override
    public boolean equals(Object object) {
        // TODO: Warning - this method won't work in the case the id fields are not set
        if (!(object instanceof Contact)) {
            return false;
        }
        Contact other = (Contact) object;

        // Every contact must have a name and surname.
        // If these match then we validate the numbers.
        if ((this.name.equals(other.name)
                && this.surname.equals(other.surname))) {
            // Check the numbers using a shallow validation
            if ((this.homeNum != null
                    && !(this.homeNum.equals(other.homeNum)))
                    || (this.workNum != null
                    && !(this.workNum.equals(other.workNum)))
                    || (this.cellNum != null
                    && !(this.cellNum.equals(other.cellNum)))
                    || (this.email != null
                    && !(this.email.equals(other.email)))) {
                return false;
            }
        }

        return true;
    }

    @Override
    public int hashCode() {
        int hash = 0;
        hash += this.name.hashCode();
        hash += this.surname.hashCode();
        if (this.email != null) {
            hash += this.email.hashCode();
        }
        if (this.workNum != null) {
            hash += this.workNum;
        }
        if (this.cellNum != null) {
            hash += this.cellNum;
        }
        if (this.homeNum != null) {
            hash += this.homeNum;
        }
        return hash;
    }

I want to imply the logic that to contacts are equal if their name and surname match and then if any of their email or phonenumbers match. The logic here is that people may share the same number. As you can see by my documentation I am ensuring that each contact must have a name and surname.
