Arrays.asList() of an array

Question

What is wrong with this conversion?

public int getTheNumber(int[] factors) {
    ArrayList f = new ArrayList(Arrays.asList(factors));  
    Co         


        

Answer 1

This works from Java 5 to 7:

public int getTheNumber(Integer... factors) {
    ArrayList f = new ArrayList(Arrays.asList(factors));
    Collections.sort(f);
    return f.get(0)*f.get(f.size()-1);
}

In Java 4 there is no vararg... :-)
