================================

The programming language Java is great to learn if you're a beginner.

Watch me solve the Java array and loop coding challenge.

me again with another question here's my solution still the wierd crash with closing input .Any ideas?









import java.util.Scanner;

public class arraytest extends Main {
    
    public static void main(String[] args){
        
        System.out.println("The average of these numbers is " +
    }// close main

    private static float getAverage(float[] nums) {
        // averages all the floats in the array
        
        float x = 0;
        for (int i = 0;i < nums.length;i++){
            
            x = x + nums[i];
        }//close forloop
       
        float y= x/nums.length;
        return y;
    }//close getAverage

    private static  float[] takeInput(int size) {
        // asks user for the values to average
        
        float[] nums = new float[size];
        Scanner input = new Scanner(System.in);
        
        for(int i = 0;i < size;i++){
            System.out.println("gimme floats!!");
            nums[i] = input.nextFloat();
            System.out.println("OM! NOM! NOM!!!");
        }//close forloop
        input.close();
        return nums;
        
    }//close takeInput

    private static int setArrSize() {
        // asks user for an int to use as the number of floats.
        Scanner input = new Scanner(System.in);
        System.out.println("How many numbers are we going to average?");
        int size = input.nextInt();
        //input.close();            WHY DOES THIS CRASH ME???    
        return size;
    }//close setArrSize

}//close Class
