Unreachable catch block for Unknownhostexception. This Exception is Never thrown from the Try statement body

Question

Speak devs, all right? I am trying to connect Mongdb to a Java application and I get this error:

Unreachable catch block for UnknownHostException. This exception is never thrown from the try statement body

They know how to fix?

Follows the code:

Connection class

package conexao;

import java.net.UnknownHostException;
import java.util.logging.Level;
import java.util.logging.Logger;

import com.mongodb.BasicDBObject;
import com.mongodb.DB;
import com.mongodb.DBCollection;
import com.mongodb.DBCursor;
import com.mongodb.Mongo;

public class Connection 
{
    DB BaseDados;
    DBCollection colecao;
    BasicDBObject document = new BasicDBObject();
    
    public Connection()
    {
        try
        {
            //Conectando ao servidor mongobd
            Mongo m = new Mongo("localhost", 27017);
            //Mongo m = new Mongo("localhost", 127.0.0.1);
            //Caso não funcione
            
            //Conectando a base de dados teste
            BaseDados = m.getDB("teste");
            
            colecao = BaseDados.getCollection("pessoa");
            
            System.out.println("Conexao efetuada com sucesso");
        }
        catch(UnknownHostException e)
        {
            Logger.getLogger(Connection.class.getName()).log(Level.SEVERE, null, e);
        }
    }
    
    public boolean inserir(String Dado)
    {
        document.put("RG", Dado);
        colecao.insert(document);
        return true;
    }
    
    public void mostrar()
    {
        DBCursor cursor = colecao.find();
        while(cursor.hasNext())
        {
            System.out.println(cursor.next());
        }
    }
    
    public boolean atualizar(String DadoAntigo, String DadoNovo)
    {
        document.put("RG", DadoAntigo);
        BasicDBObject DocNovo = new BasicDBObject();
        document.put("RG", DadoNovo);
        colecao.findAndModify(document,DocNovo);
        return true;
    }
    
    public boolean remover(String Dado)
    {
        document.put("RG", Dado);
        colecao.remove(document);
        return true;
    }
    
}

Main Class

package conexao;

public class Principal {

    public static void main(String[] args)
    {
        Connection conexao = new Connection();
        
        conexao.inserir("9254063");
        conexao.mostrar();

    }

}
