forEach

public static <T> void forEach(List<T> list,

Iterates over the section of the list covered by the specified indexes. The indexes are both inclusive. If the from is less than the to, the list is iterated in forward order. If the from is greater than the to, then the list is iterated in the reverse order.

e.g.
 MutableList<People> people = FastList.newListWith(ted, mary, bob, sally);
 ListIterate.forEach(people, 0, 1, new Procedure<Person>()
 {
     public void value(Person person)

Iterates over the section of the list covered by the specified indexes. The indexes are both inclusive. If the from is less than the to, the list is iterated in forward order. If the from is greater than the to, then the list is iterated in the reverse order. The index passed into the ObjectIntProcedure is the actual index of the range.

e.g.
 MutableList<People> people = FastList.newListWith(ted, mary, bob, sally);
 ListIterate.forEachWithIndex(people, 0, 1, new ObjectIntProcedure<Person>()
 {
     public void value(Person person, int index)
     {
