<?php
namespace Mageplaza\HelloWorld\Block;
class HelloWorld extends \Magento\Framework\View\Element\Template
{    
    protected $_productCollectionFactory;
        
    public function __construct(
        \Magento\Backend\Block\Template\Context $context,        
        \Magento\Catalog\Model\ResourceModel\Product\CollectionFactory $productCollectionFactory,

    )

        $this->_productCollectionFactory = $productCollectionFactory;    
        parent::__construct($context, $data);
    }
    
    public function getProductCollection()
    {
        $collection = $this->_productCollectionFactory->create();
