(
Identical arrays
) The arrays
list1
and
list2
are
identical
if they have the same
contents. Write a method that returns
true
if
list1
and
list2
are identical,
using the following header:
public static boolean
equals(
int
[] list1,
int
[] list2)
Write a test program that prompts the user to enter two lists of integers and dis-
plays whether the two are identical. Here are the sample runs. Note that the first
number in the input indicates the number of the elements in the list.

(
Math: combinations
) Write a program that prompts the user to enter 10 integers
and displays all combinations of picking two numbers from the 10.

(
Game: pick four cards
) Write a program that picks four cards from a deck of 52
cards and computes their sum. An Ace, King, Queen, and Jack represent 1, 13, 12,
and 11, respectively. Your program should display the number of picks that yields
the sum of 24.

Pattern recognition: consecutive four equal numbers
) Write the following
method that tests whether the array has four consecutive numbers with the same
value.
VideoNote
Consecutive four
public static boolean
isConsecutiveFour(
int
[] values)
Write a test program that prompts the user to enter a series of integers and displays
true if the series contains four consecutive numbers with the same value. Other-
wise, display false. Your program should first prompt the user to enter the input
size—i.e., the number of values in the series.

(
Merge two sorted lists
) Write the following method that merges two sorted lists
into a new sorted list.
public static int
[] merge(
int
[] list1,
int
[] list2)
Implement the method in a way that takes
list1.length
+
list2.length
comparisons. Write a test program that prompts the user to enter two sorted lists
and displays the merged list. Here is a sample run. Note that the first number in the
input indicates the number of the elements in the list.
