I'm using input.xsd schema file:
<?xml version="1.0" encoding="UTF-8"?>
<xsd:schema xmlns:xsd="http://www.w3.org/2001/XMLSchema">
<xsd:element name="Mobiles">
<xsd:complexType>
<xsd:sequence>
<xsd:element name="Mobile" type="Mobile" maxOccurs="unbounded"/>
</xsd:sequence>
</xsd:complexType>
</xsd:element>
<xsd:complexType name="Mobile">
<xsd:sequence>
<xsd:element name="Model" type="xsd:string"/>
<xsd:element name="OS">
<xsd:simpleType>
<xsd:restriction base="xsd:string">
<xsd:enumeration value="Android"/>
</xsd:restriction>
</xsd:simpleType>
</xsd:element>
<xsd:element name="Origin" type="xsd:string"/>
<xsd:element name="Material" type="xsd:string"/>
<xsd:element name="Samsung" type="Samsung"/>
</xsd:sequence>
</xsd:complexType>
<xsd:complexType name="Samsung" mixed="true">
<xsd:sequence>
<xsd:element name="Wlan">
<xsd:simpleType>
<xsd:restriction base="xsd:string">
<xsd:enumeration value="802.11"/>
</xsd:restriction>
</xsd:simpleType>
</xsd:element>
<xsd:element name="CardSlot" type="xsd:string"/>
<xsd:element name="RadioAvailability" type="xsd:boolean" default="true"/>
<xsd:element name="BluetoothAvailability" type="xsd:boolean" default="false"/>
</xsd:sequence>
</xsd:complexType>
</xsd:schema>
And input.xml file looks like:
<?xml version="1.0" encoding="UTF-8" standalone="no"?>
<Mobiles
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:noNamespaceSchemaLocation="input.xsd">

</Mobile>

I've followed this answer as example without namespaces for schema and this for better theoretical understanding.
But I'm always getting the issue locally in console when I'm trying to validate xsd schema file:
cvc-elt.1: Cannot find the declaration of element 'xsd:schema'.
org.xml.sax.SAXParseException; systemId: file:///F:/IdeaProject/TestProject/input.xsd; lineNumber: 2; columnNumber: 58; cvc-elt.1: Cannot find the declaration of element 'xsd:schema'.

using logic for validating like:
public void parse(boolean validate) throws ParserConfigurationException, SAXException, IOException {
System.out.println("Invoking parse()");
// obtain DOM parser
DocumentBuilderFactory dbf = DocumentBuilderFactory.newInstance();
try{
dbf.setFeature("http://xml.org/sax/features/
