Create a program in Java to print the sum of all Fibonacci numbers within the given range.
Erroneous Code Reference:
```java
public class Fibonacci {
public static void main(String[] args) {
int range = 10;
int[] fibonacci = new int[range + 1];
fibonacci[0] = 0;

Design a Java algorithmic method that not only identifies the peak numeric value in a predefined array of integers, but also determines the position of the second highest value in relation to the highest. In cases where the highest value appears more than once, count the occurrences and denote the positions of the seco... | codefeedback | [
