How to send values entered in two separate <h:inputText/> elements to a single method in java?

Question

I have a problem as I mentioned in the topic title. I want to pass the values from two different <h:inputText/> elements as parameters to a method that takes two parameters in Java and send the result to a single <h:outputText/> element. I don't know how to do this.

For this problem, I created the setter and getter methods separately on the CDI Bean to represent both <h:inputText/> elements. Sample codes are as follows.

            <br/>
            <h:outputLabel value="Tarih2"/><br/>
            <h:inputText id="tarih2Text" p:placeholder="gg/aa/yyyy" value="#{dateCDIBean.date2}"/>
            <br/>
            <h:commandButton id="btn" value="Farkı Hesapla"/>
            <br/>
            <h:outputText id="cikti" value="#{dataCDIBean.value}"/>
        </h:form>
    </h:body>
</html>

    public String getDate1() {

    }

    public void setDate1(String date1) {
        TarihKontrol tk1 = new TarihKontrol();
        tk1.Kontrol(date1);
        if (tk1.hataliMi == false) {
            this.date1 = date1;
        }
    }

    public String getDate2() {
        return date2;
    }

    public void setDate2(String date2) {
        TarihKontrol tk2 = new TarihKontrol();
        tk2.Kontrol(date2);
        if (tk2.hataliMi == false) {
            this.date2 = date2;
        }
    }

    public String hesapla() {
        if (date1 != null && date2 != null) {
            TarihFark fark = new TarihFark(date1, date2);
            date1 = "";
            date2 = "";
            return fark.GunFark() + " gün, " + fark.AyFark() + " ay, " + fark.YilFark() + " yıl";
        } else {
            return "Yukarıdaki alanlara \"gg/aa/yyyy\" ya da \"gg.aa.yyyy\" formatında tarih değeri giriniz.";
        }
    }

    public String getValue() {
        return hesapla();
    }

    public void setValue(String value) {
        this.value = value;
    }
}

How can I apply the solution in the topic title as an alternative to what I did above? Or can you tell me if this is possible?

        <h:form id="indexForm">
            <h:outputLabel value="Tarih1"/><br/>
            <h:inputText id="tarih1Text" value="#{dateCDIBean.date1}"/>
            <br/>
            <h:outputLabel value="Tarih2"/><br/>
            <h:inputText id="tarih2Text" value="#{dateCDIBean.date2}"/>
            <br/>
            <h:commandButton id="btn" value="Farkı Hesapla" action="#{dateCDIBean.concdata()}"/>
            <br/>
            <h:outputLabel id="cikti" value="#{dateCDIBean.value}"/>
        </h:form>

    public void concdata() {
        value = date1 + date2;
        PrimeFaces.current().ajax().update("indexForm:cikti");
    }
