How to add user input in an array
Hey I'm trying to have the user input a value and store it in an array. The only problem is it's saying I can't do it due to a lack of percision (double to int). I've looked and all my values are double. Am I doing it wrong. Thanks.
Code:
import java.util.Scanner;
public class RainfallTester {
public static void main(String [] args){
Scanner scan = new Scanner(System.in);
Rainfall temp = new Rainfall();
double rain;
for(double j=0; j<temp.rainfall.length;j++ ){
System.out.println("What is the total rainfall for the month:");
temp.rainfall[j] = scan.nextDouble(); //this is giving me an error
}
System.out.println("The total rainfall for the year is "+temp.getTotal());
System.out.println("The average monthly rainfall is "+temp.getAvg());
System.out.println("The month with the most rainfall is "+temp.getMax());
System.out.println("The month with the least rainfall is "+temp.getMin());
}
}
Another question is how would I get values back such as the total do I use counter or something.
Code:
public class Rainfall {
double avgRain;
double sum = 0;
double rainfall[] = new double[11];
double getTotal(){
return sum += rainfall[];
}
double getAvg(){
sum += rainfall[];
return sum/rainfall.length;
}
double getMax(){
}
double getMin(){
}
}
Thanks. |
