Rule: Optimization7

Synopsis:	Use asList instead of tight loops
Language:	Java
Severity Level:	3
Category:	Optimization

Description:

The class java.util.Arrays has a "asList" method that should be use when you want to create a new List from an array of objects. It is faster than executing a loop to cpy all the elements of the array one by one

public class Test {
    public void foo(Integer[] ints) {
    // could just use Arrays.asList(ints)
     List l= new ArrayList(10);
     for (int i=0; i< 100; i++) {
      l.add(ints[i]);
     }
     for (int i=0; i< 100; i++) {
      l.add(a[i].toString()); // won't trigger the rule
     }
    }
   }
