Answer 1

In magento2 this can be achieves as :

protected $objectManager;

public function __construct(
     .....
    \Magento\Framework\ObjectManagerInterface $objectManager,
     .......
    ) {
     ...
     $this->objectManager = $objectManager;
     ........
   }


  public function getOrder($invoice_id){
    $invoice= $this->objectManager->create('Magento\Sales\Model\Order\Invoice')->load($invoice_id);
    return $invoice->getOrder();
  } 

Answer 2

Use factory method instead of object manager

protected $invoiceFactory;

public function __construct(
    ...
    \Magento\Sales\Model\Order\InvoiceFactory $invoiceFactory
    ...
) {
    ...
    $this->invoiceFactory = $invoiceFactory;
    ...
}

public function getOrderByInvoice($invoiceId)
{
    $invoice = $this->invoiceFactory->create()->load($invoiceId);
    return $invoice->getOrder();
}
