Is there any way to access page properties if only page path is given?

Question

I want to access the properties of specific page but I only have its path with me in the sling model.
how can I access the page properties if only the path is given?
 
I have tried using : 
 
@ScriptVariableprivate ResourceResolver resourceResolver;
Page rootPage = resourceResolver.getResource(PAGE_PATH).adaptTo(Page.class);
 but I am getting a null pointer exception in this.
Please help me find out how to do it.
 
Thank you

Follow below lines of code In sling init method

@Model(adaptables = {
        Resource.class }, defaultInjectionStrategy = DefaultInjectionStrategy.OPTIONAL, resourceType = "")
@Exporter(name = ExporterConstants.SLING_MODEL_EXPORTER_NAME, extensions = ExporterConstants.SLING_MODEL_EXTENSION)
public class YourModel{
@SlingObject
    ResourceResolver resourceResolver;
init(){
Resource resource = resourceResolver.getResource("path");
 PageManager pageManager =  resource.getResourceResolver().adaptTo(PageManager.class);
Page containingPage = pageManager.getContainingPage(resource);
if(Objects.nonNull(containingPage){
 ValueMap pageProperties = containingPage.getProperties();
}
}
}

OR

 PageManager pageManager = resourceResolver.adaptTo(PageManager.class);
Page page = pageManager.getPage(currentPage.getPath());// for current page
Page page = pageManager.getPage("provided path");

Hi @rahul234dabas ,If resource is null, alternatively you can use PageManager pageManager = resourceResolver.adaptTo(PageManager.class);Page currentPage = pageManager.getPage("/content/page/en/");
