Front 1

List<E> boolean .add(E obj)

Back 1

Adds the element obj to the end of the List. Returns true.

Front 2

List int .size()

Back 2

returns the integer size of the List

Front 3

List E .get(int index)

Back 3

Returns the object of type E located at index index.

Front 4

List E set(int index, E element)

Back 4

Replaces item at listed index with element. Returns the object of type E that used to be at index.

Front 5

List void .add(int index, E element)

Back 5

Inserts element at index index. All elements after index have their index incremented

Front 6

List E.remove(int index)

Back 6

Removes and returns the element at index index. Elements with indexes greater than index have their indeces decremented. List size is decremented.

Front 7

What is List<E>

Back 7

An Interface

Front 8

What class most notably implements List<E>

Back 8

ArrayList<E>

Front 9

int value of strings
'fish".compareTo("fish")

Back 9

0

Front 10

int value of Strings apple.compareTo(banana)

Back 10

-x

Front 11

int value of Strings
salmon.compareTo(cod)

Back 11

+x

Front 12

1+4=?

Back 12

5

Front 13

"1"+"4" =

Back 13

14

Front 14

"fish" + 455 = ?

Back 14

fish455

Front 15

What is the name of the operator used in 1+4=5?

Back 15

addition

Front 16

What is the name of the operator used in "1" + "4" = "14"

Back 16

concatenation

Front 17

String int .length() does?

Back 17

Returns the length of the String.

Front 18

String String .substring(int index) does?

Back 18

Returns a string that is a substring of the original. It begins at index, and goes until the end of hte string! This is often more efficient than using .substring(startindex, endindex)

Front 19

String String .substring( int startindex, int endindex)

Back 19

Takes a substring from startindex to endindex-1, so while it takes the character at startindex, endindex is excluded.

Front 20

String int indexOf(String str)

Back 20

Returns the index of the beginning of the first occurrance of str in String. If str is not present, returns -1.
