Question 1: Simple COVID-19 Diagnostics Expert SystemWith regard to the ravaging impact of the COVID-19 pandemic which is caused by the SARS-CoV-2;the World Health Organization (WHO) has long made public some symptoms, which the generalpopulace can employ as a basic first-aid reference/guide, to diagnose the severity of a patient’ssymptom(s). Thus, the table below illustrates the severity of these symptoms in patients, based onclinical records, since February 2020 till date.Therefore, write a Java program correctly such that your source code will accomplish the following:1. Display all the Symptom Codes (from 10 – 23 only) and the corresponding SymptomDescriptions to the user using the following format: Symptom Code = Symptom Description. Do not include the Symptom Category in your screen display to the user.2. Display a prompt message for the user to enter a Symptom Code.3. The Symptom Codes: 10 – 13, 14 – 20, and 21 – 23 indicate the Most CommonSymptoms, the Less Common Symptoms, and the Critical Symptoms of COVID19, respectively.4. Validate the user’s input to ensure that a valid (numeric value or Symptom Code) has been entered. If otherwise, display the respective error message and end the program with a note to the user to retry again.5. If a user enters a valid numeric value or Symptom Code, process the input within your code and return the respective Symptom Category alongside some corresponding advice note as shown below:Symptom Category Advice NoteMost and Less Common SymptomsYou are experiencing a common symptom with regard to either COVID-19 or a respiratory infection (e.g. flu).
