Each patient receives an identity number which prioritizes the order of emergency for the patient. The lower the number is, the higher the emergency will be. Use java.util.PriorityQueue to write a java program to create the emergency room registration database. The patient.txt is the input file for patient record. Download patient.txt, Patient.java from Moodle to perform following specifications: (i) Load all records from the input file. (ii) At the end, print the list in assigned priority order.
