binary search
This search algorithm repeatably divides the portion of an array
add
To insert an item at a specific location in an arraylist object you use this method
braces
When initializing a two-dimensional array, you enclose each each rows initialization list in______.
true
An arrayList automatically expands in size to accommodate the items store in it
false
An arrays size declaratory can be a negative integer and equivalent
subscript
Each element of an array is accessed by a number kown as
size declaration
in an array declaration this indicates the number of elements that the array will have
true
java does not allow a statement to use a subscript that is outside the range of valid subscripts for anarray
n/2
this is the typical number of comparisons performed by the sequential search on an array of N elements
sequential search
this search algorithm repeatedly divides the portion of an array being searched in half
remove
to delete an item from an arraylist object you use the method
size
to determine the number of items stored in an arraylsit object, you use this method
true
when an array is passes to a method, the method has access to the original array.
when the program runs
Array bounds checking happens
false
The first size declaratory in the declaration of a two dimensional array represents the number of columns. the second size declarator represents the number or rows
true
The java compiler does not display an error message when it processes a statement that used an invalid subscript
true
The subscriot of the last element in a single- dimensioal array is one less than the total number of elements in the array
true
The values in an initialization
length
This array field hold the number of elements that the array has
true
an arrays size declaration are legal and equivalent: int [ ] numbers; int numbers [ ];
0
the first subscript in an array is always________
1 less than the number of elements
the last subscript is an array is always ___________
true
A two dimensional array has multiple length fields
