14. Variables - Naming
• Subsequent characters also can be numbers
• Case sensitive
• No spaces
• Examples:
name
firstName
phoneNumber

39. Example
ArrayList<String> arrList = new ArrayList<String>();
arrList.add(“A”);
arrList.add(“AB”);
arrList.add(“ABC”);
arrList.add(“ABCD”);
// using indices
arrList.set(0, arrList.get(1));
arrList.set(1, “foo”);
// out of bound?
arrList.set(9, “bar”);
40. Example
• Suppose an ArrayList A1
• What does the following line mean?
List<String> list =
new ArrayList<String>(A1);
41. for-each Construct
• Looping by indices
• for-each, parallel execution
for (Object o : collection)
System.out.println(o);
42. Collection Operations
List<Type> list1 = new ArrayList<Type>();
// …
List<Type> list2 = new ArrayList<Type>();
// …
List<Type> list3 = new ArrayList<Type>(list1);
list3.addAll(list2);
43. List Algorithms
• sort — sorts a List using a merge sort algorithm, which provides a
fast, stable sort. (A stable sort is one that does not reorder equal
elements.)
• shuffle — randomly permutes the elements in a List.
• reverse — reverses the order of the elements in a List.
• rotate — rotates all the elements in a List by a specified distance.
• swap — swaps the elements at specified positions in a List.
• replaceAll — replaces all occurrences of one specified value with
another.
• fill — overwrites every element in a List with the specified value.
• copy — copies the source List into the destination List.
• binarySearch — searches for an element in an ordered List using the
binary search algorithm.
• indexOfSubList — returns the index of the first sublist of one List that
is equal to another.
• lastIndexOfSubList — returns the index of the last sublist of
one List that is equal to another.
