Taxonomy terms load in drupal 8.

In drupal 7, we have taxonomy_term_load($tid), taxonomy_term_load_multiple($tids) functions for load the taxonomy term or multiple terms but now in drupal 8 syntax is changed and now Single/Multiple term load by Term::load($tid)
or
Add the name space at the top of the page.
\Drupal\taxonomy\Entity\Term::load($tid);

If we are using Symfony library and calling name space 
use Drupal\taxonomy\Entity\Term;
use Drupal\taxonomy;

or direct use in function calling time like  \Drupal\taxonomy\Entity\Term::load($tid);

Example:
$term_detail_array = \Drupal\taxonomy\Entity\Term::load($tid);
or
$term_detail_array = Term::load($tid); //if we are already using taxonomy library..

Then get the fields detail by $term_detail_array like,

Term id:  $term_detail_array ->tid->value;
Term name:  $term_detail_array ->name->value;
Term manually added field:  $term_detail_array ->get('field_machine_name')->value;  // manually added field value..
Term image field:  $term_detail_array ->field_machine_name->entity->getFileUri();

 If we have field with entity reference then field value will be in form of $term_detail_array ->get('field_machine_name')->target_id;
or
If we have field without entity reference then field value will be in form of $term_detail_array ->get('field_machine_name')->value;

Now we will discuss on Term::loadMultiple.
And the syntax is $terms = \Drupal\taxonomy\Entity\Term::loadMultiple($tids); // here $tids is the array of multiple tid..
$terms = \Drupal\taxonomy\Entity\Term::loadMultiple($tids); 
foreach ($terms as $term) {  //then the fields value will be..
$term_id = $term->tid->value;
$term_name = $term->name->value;
$term_file field = $term->field_machine_name->uri;
}
and so on..
