如何使用 Do-While 循环构造程序

Question

public static double avgArry(double[] a) {
        double sum = 0;
        double average = 0;
        int i =0;

        while(i<a.length) {
        sum += a[i] ;
        average = sum / a.length;
        ++i;
    }
        return average;
}   

    public static void main(String[] args) {
        // TODO Auto-generated method stub
double j;
        double[] array = {1.5, 20.3, 4.5, 5.5, 10.3, 450, 20.4, -22.3};

        j = avgArry(array);

        System.out.format("The average is: %.3f" , j);


}


}

The program above calculates the average of elements in an array. But my issue is how can I put it in Do-While loop? While loop and for-loop have been done by me. Please help me out:,,,(. Please don't judge me I'm new to Java.

The average is: 61.275

This should do it. Keep in mind for this to work you need to have at least one element in your array

  do{
       sum += a[i] ;
       average = sum / a.length;
       ++i;
    }
    while(i<a.length);
