Chapter 8, Problem 8.29PE
(Identical arrays) The two-dimensional arrays m1 and m2 are identical if they have the same contents. Write a method that returns true if m1 and m2 are identical, using the following header:

3. (Eliminate duplicates) Write a method that returns a new array by eliminating the duplicate values in the array using
the following method header:
public static int[] eliminate Duplicates (int[] list)
Write a test program that reads in ten integers, invokes the method, and displays the result.
1)Write a method that takes an array of ints and returns the sum of all numbers that are even. For example, given an array {3, 4, 6}, you would return 10.
2)For this exercise, you are given an array of integers. Return true if every element in the array is an odd number, otherwise return false.
3)
Given an array of strings, return the array in reverse order.
For example, given:
reverse({"one", "two", "three"});
You would return:
{"three", "two", "one"}
4)
For this exercise, you need to shift all the elements in the array one space to the right (increase the index of the element by 1). The last element will wrap around and become the new first element.
For example, given:
moveUp({"first", "second", "third", "fourth"});
You would return:
{"fourth", "first", "second", "third"}
. DO NOT REJECT THE QUESTION. ----
Write a Java program that asks the user to enter an array of integers in the main The program will ask the user for the number of integer elements to be put in the array, and then ask the user for each element of the array. The program then calls a method named isSorted() that accepts an array of integers and returns true if the list is in sorted (increasing) order and false otherwise. For example, if arrays named arr1 and arr2 store [10, 20, 30, 41, 56] and [2, 5, 3, 12, 10] respectively, the calls sorted(arr1) and isSorted(arr2) should return true and false respectively. Assume the array has at least one integer element. A one-element array is considered to be sorted.

- Exercise (Array and Method): Write a method called arrayToString(), which takes an int array and return a String in the form of {a1, a2, ..., an}. Take note that there is no comma after the last element. The method's signature is as follows: public static String arrayToString(int[] array) Also write a test driver to test this method (you should test on empty array, one-element array, and n-element array). Notes: This is similar to the built-in function Arrays.toString(). You could study its source code.
