I don't understand step 3 also can someone check if I did the setTemps method right?
Step 2: Temps Class For lab9 we will be using arrays to store the high temperatures for a given month and perform some simple statistics for them. You will create a Temps class to store the values and perform the calculations. (Data that you use for this lab was obtained from the national weather service and city‐data.com – from June 2004)
Create a new class called Temps. This class has the following instance variables:
Write the following methods:
Example: String [] aux = tempStr.split(",");
Example: Converting the first entry of the aux array into an int and assigning the value to the first position of temps.
temps [0] = Integer.parseInt(aux[0]);
The average high temperature for June, 2004 was: 75.37
The high temperature for June, 2004 was: 90
The lowest high temperature for June, 2004 was: 63
Daily Temperatures
==================
Day 1: 73ºF
Day 2: 68ºF
Day 3: 74ºF
.
.
.
Day 30: 76ºF
Step 3: Create the main method
The main method could be included in the Temps class or you could create another class – the driver class - if you prefer that.
"73,68,74,74,77,81,85,90,85,72,63,74,83,80,81,81,79,79,69,71,69,70,75,70,68,70,73,72,79,76"
public class Temps {
private String monthName;
private int year;
private int [] temps;
private int highest;
private int lowest;
private int total;
private String output;
private String [] aux;
public Temps () {
monthName = "June";
year = 2004;
highest = 0;
lowest = 0;
total = 0;
}
public Temps (String monthName, int year) {
this.monthName = monthName;
this.year = year;
}
public void setTemps (String tempStr) {
temps = new int [31];
String [] aux = tempStr.split(",");
for(int i = 0; i < temps.length; i++) {
temps [i] = Integer.parseInt(aux[0]);
}
}
public int getAverage() {
for(int i = 0; i < temps.length; i++){
total = total + temps[i];
}
return total / temps.length;
}
public int getHighest() {
int highest = temps[0];
for (int i = 1; i < temps.length; i++) {
if (temps[i] > highest) {
highest = temps[i];
}
}
return highest;
}
public int getlowest() {
int lowest = temps[0];
for (int i = 1; i < temps.length; i++) {
if (temps[i] < lowest) {
lowest = temps[i];
}
}
return lowest;
}
public String toString() {
for (int i = 1; i < temps.length; i++) {
String output = String.format("The average high temperature for " +
monthName + "," + year + "was: " + (total / temps.length) +
"\n" + "The high temperature for " + monthName + "," + year + "was:
" + highest +
"\n" + "The lowest high temperature for " + monthName + "," + year
+ "was: " + lowest);
}
return output;
}
public void printTemps() {
for (int i = 0; i < temps.length; i++) {
System.out.println("Daily Temperatures ");
System.out.println("================== ");
System.out.println("Day " + (i + 1) + ": " + temps + " F");
}
}
}
Step 3 is asking you to create a driver class which is a class that contains the main() method and demonstrates the methods in the other class (Temps). I created a class named "Main" which follows the instruction in step 3. There were tiny logical errors in the printTemps() and setTemps(), so i corrected those. however, I haven't checked rest of the methods
