Question

Write the method loadArray. The method will declare and open a file stream and connect it to the external file passed in. It will then read patient names into the patients array and their temperatures into the temps array. The method should compute/determine the number of patients in the file. Make sure you do all steps of file VO] A sample file, and some declarations and a sample function call are given Sample File Mickey 102.5 Minnie 1.6 Donald 101.5 Daisy 95.6 Code double (1 temp w doubles String ] patients - Strings int Patients lodrray("data.tut", patients, temps,

Answer 1

public static int loadArray(String filename, String[] patients, double[] temps, int numPatients) {
    File file = new File(filename);    // read a file and create a file.
    try {
        Scanner fin = new Scanner(file);    // create a scanner to read from file
        numPatients = 0;
        while (fin.hasNext() && numPatients < patients.length) { // read each line from file
            patients[numPatients] = fin.next();
            temps[numPatients] = fin.nextDouble();
            ++numPatients;
        }
        fin.close();    // close file.
    } catch (IOException e) {
        System.out.println("Error. " + file.getAbsolutePath() + " does not exists!");   // if file does not exist, report an error
    }
    return numPatients;
