In Magento 2 we can get Customer’s Default billing and Shipping address by customer id using below code snippet,

Using the Block file get the customer’s default billing and shipping address,

<?php

namespace Rbj\Customer\Block;

class CustomerAddressById extends \Magento\Framework\View\Element\Template
{
    public function __construct(
        \Magento\Framework\View\Element\Template\Context $context,
        \Magento\Customer\Api\AccountManagementInterface $accountManagement,
        \Magento\Customer\Model\Address\Config $addressConfig,
        \Magento\Customer\Model\Address\Mapper $addressMapper,
        \Magento\Framework\App\Http\Context $httpContext,
        array $data = []
    ) {
        $this->accountManagement = $accountManagement;
        $this->_addressConfig = $addressConfig;
        $this->addressMapper = $addressMapper;
        parent::__construct($context, $data);
    }

    /**
     * $customerId
     */
    public function getDefaultShippingAddress($customerId)
    {
        try {
            $address = $this->accountManagement->getDefaultBillingAddress($customerId);
        } catch (NoSuchEntityException $e) {
            return __('You have not set a default shipping address.');
        }
        return $address;
    }

    /**
     * $customerId
     */
    public function getDefaultBillingAddress($customerId)
    {
        try {
            $address = $this->accountManagement->getDefaultBillingAddress($customerId);
        } catch (NoSuchEntityException $e) {
            return __('You have not set a default billing address.');
        }
        return $address;
    }
    /* Html Format */
    public function getDefaultShippingAddressHtml($address) {
        if ($address) {
            return $this->_getAddressHtml($address);
        } else {
            return __('You have not set a default Shipping address.');
        }
    }
    /* Html Format */
    public function getDefaultBillingAddressHtml($address) {
        if ($address) {
            return $this->_getAddressHtml($address);
        } else {
            return __('You have not set a default billing address.');
        }
    }

    /**
     * Render an address as HTML and return the result
     *
     * @param AddressInterface $address
     * @return string
     */
    protected function _getAddressHtml($address)
    {
        /** @var \Magento\Customer\Block\Address\Renderer\RendererInterface $renderer */
        $renderer = $this->_addressConfig->getFormatByCode('html')->getRenderer();
        return $renderer->renderArray($this->addressMapper->toFlatArray($address));
    }
}

Call the required function in the template file,

<?php
$customerId = 1;

$shippingAddress = $block->getDefaultShippingAddress($customerId);
//echo "<pre>";print_r($shippingAddress->__toArray());

$billingAddress = $block->getDefaultBillingAddress($customerId);
//echo "<pre>";print_r($billingAddress->__toArray());

echo $block->getDefaultShippingAddressHtml($shippingAddress);
echo $block->getDefaultBillingAddressHtml($billingAddress);
?>

In Magento 2 we can get the Current Customer Default billing and Shipping address using the given code snippet.

If the Customer is not logged in they will display customer is not logged in.
Using Block file get logged in customer default billing and shipping address,

<?php
namespace Rbj\CustomerAddress\Block;

class Addressinfo extends \Magento\Framework\View\Element\Template
{
    public function __construct(
        \Magento\Framework\View\Element\Template\Context $context,
        \Magento\Customer\Helper\Session\CurrentCustomerAddress $currentCustomerAddress,
        \Magento\Customer\Model\Address\Config $addressConfig,
        \Magento\Customer\Model\Address\Mapper $addressMapper,
        \Magento\Framework\App\Http\Context $httpContext,
        array $data = []
    ) {
        $this->currentCustomerAddress = $currentCustomerAddress;
        $this->_addressConfig = $addressConfig;
        $this->addressMapper = $addressMapper;        
        $this->httpContext = $httpContext;
        parent::__construct($context, $data);
    }

    /**
     * Array for Shipping Address
     *
     * @return \Magento\Framework\Phrase|string
     */
    public function getDefaultShippingAddress()
    {
        try {
            $address = $this->currentCustomerAddress->getDefaultShippingAddress();
        } catch (NoSuchEntityException $e) {
            return __('You have not set a default shipping address.');
        }
        return $address;
    }

    /**
     * Array for Billing Address
     *
     * @return \Magento\Framework\Phrase|string
     */
    public function getDefaultBillingAddress()
    {
        try {
            $address = $this->currentCustomerAddress->getDefaultBillingAddress();
        } catch (NoSuchEntityException $e) {
            return __('You have not set a default billing address.');
        }
        return $address;
    }
    /* Html Format */
    public function getDefaultShippingAddressHtml($address) {
        if ($address) {
            return $this->_getAddressHtml($address);
        } else {
            return __('You have not set a default Shipping address.');
        }
    }
    /* Html Format */
    public function getDefaultBillingAddressHtml($address) {
        if ($address) {
            return $this->_getAddressHtml($address);
        } else {
            return __('You have not set a default billing address.');
        }
    }

    /**
     * Render an address as HTML and return the result
     *
     * @param AddressInterface $address
     * @return string
     */
    public function _getAddressHtml($address)
    {
        /** @var \Magento\Customer\Block\Address\Renderer\RendererInterface $renderer */
        $renderer = $this->_addressConfig->getFormatByCode('html')->getRenderer();
        return $renderer->renderArray($this->addressMapper->toFlatArray($address));
    }

    /*
     * return bool
     */
    public function getLogin() {
        return $this->httpContext->isLoggedIn();
    }
}

Call a required function in the template file,

<?php
$isLoggedin = $block->getLogin(); //output for logged in customer as 'roni_cost@example.com'
if($isLoggedin) {
    $shippingAddress = $block->getDefaultShippingAddress();
    //echo "<pre>";print_r($shippingAddress->__toArray());
    $billingAddress = $block->getDefaultBillingAddress();
    //echo "<pre>";print_r($billingAddress->__toArray());
    echo $block->getDefaultShippingAddressHtml($shippingAddress);
    echo $block->getDefaultBillingAddressHtml($billingAddress);
} else {
    echo __('You have not logged in.');
}

Output for the customer has a shipping address exist,

echo "<pre>";print_r($shippingAddress->__toArray());
