Question

Instructions:

For each of the questions below, design a class with the following basic structure:

Data members:

arr : array to store elements

n : size of the array

Member functions:

Parameterised constructor to allocate memory to array (optional)

void input() : To input values into the array

void compute() : To perform the required task for each question. (You may change the name and make it relevant to the task of the question)

void display() : To display as per the requirement of each question

Write a main() method to create an object of the class and call all other methods in appropriate order.



Questions:



Write a program in java to reverse the array. (The same array should be reversed). Display the array original array as well as reversed array



For example: arr = {1,2,3,4,5,6}

After reversal arr = {6,5,4,3,2,1}



Write a Program in Java to find the duplicate values in an array. Display the original array and all the duplicate values along with its frequency of duplication.



For example: arr = {1,2,3,2,4,5,4,2,1,2}

It should display:

Duplicate elements:

1 - 2 times

2 - 4 times

4 - 2 times



Write a Java program to find all pairs of elements in an array whose sum is equal to a specified number (to be taken as user input).



For example: arr = {2,5,3,8,4,10,-3,-1}

Sum to be checked = 7

It should display:

Pairs whose sum is 7 are:

2 and 5

3 and 4

-3 and 10

8 and -1



4. Write a Java program to find maximum product of two integers in an array of integers.



For example: arr = {2,5,3,8,4,10}



It should display:

Maximum product of two integers in the array is = 80
