How can I convert values here:
List<String> values = new ArrayList<String>
to :
ArrayList<Custom>
EDIT:
public class Custom {
public Custom Parse(String input) {
// What should I do here?
}
}

You could use:
List<Custom> customList = new ArrayList<Custom>();
for (String value: values) {
customList.add(new Custom(value));
}
Although it would be better just to add a constructor with a String argument:
class Custom {
private final String input;
public Custom(String input) {
this.input = input;
}
// not needed but implemented for completeness
public static Custom parse(String input) {
return new Custom(input);
}
}

Assuming your list of Custom objects has the same size with values list.
With one enhanced for-loop, set the appropriate fields of your objects like this:
int i=0;
for(String str:values)
customList.get(i++).setSomeProperty(str);

you can find a solution using Google Collections libraries on this thread Converting a List<String> to a List<Integer> (or any class that extends Number)
