- Need help with this question Write a Java program that asks the user to enter an array of integers in the main method. The program should prompt the user for the number of elements in the array and then the elements of the array. The program should then call a method named minGap that accepts the array entered by the user as a parameter and returns the minimum 'gap' between adjacent values in the array. The main method should then print the value returned by the method. The gap between two adjacent values in an array is defined as the difference in value between the first element and the second element. For example, suppose the user entered the following array of integers {1, 3, 6, 5, 12} The first gap is 2 (3 - 1), the second gap is 3 (6 - 3), the third gap is 1 (6 - 5) and the fourth gap is 5 (12 - 6). Thus, the call of minGap(array) should return 1 because that is the smallest gap in the array. If you are passed an array with fewer than 2 elements, you…Write a Java program named Findletter that asks the user to enter 10 letters and store them in an array. Then it should ask the user to enter a letter (char value) to search for it. Then, if the entered letter is found, the program should display the message "The letter is in the array", otherwise it should display the message "The letter is not in the array".Write a java program to create prices of Shopping Cart items that provides a menu: 1: Create a new price for each item in the Cart list 2: Print the price of a particular item 0: Exit Enter your choice: Define an array: ShoppingCart which stores prices of items. Define another array: ItemsNames of the same size that stores names of such items. Assume that there are 10 items. When the user presses 1, the program call a method that creates a new price for each item in the array using random numbers between 1 and 1000 AED [not inclusive]. If the user presses 2, the program call a method that prints the name of the requested item and its price. Use switch case statement for choosing among the menu options. Make a method to display the menu to give the user the possibility to use the menu as much as he/she wants.

- In java Write a program that uses a 2-D array to store the highest and lowest temperatures for each month of the year. The program should output the average high, average low, and highest and lowest temperatures of the year. Your program must consist of the following methods with their appropriate parameters:a.) getData: This method reads and stores the data in the 2-D array.b.) averageHigh: This method calculates and returns the average high temperature of the year.c.) averageLow: This method calculates and returns the average low temperature of the year.d.) indexHighTemp: This method returns the index of the highest temperature in the array.e.) indexLowTemp: This method returns the index of the lowest temperature in the array.Use the following input:High temp for each month: 30 40 45 60 70 90 89 95 79 90 70 40Low temp for each month: 10 -10 20 30 50 75 85 79 50 80 30 20QUESTION 2 Write a Java program to input a single dimensional integer array of size 8. Pass the array to a method named countBigNumbers that return integer. In this method, count the array elements that are bigger than 50 and place them in another array. Display the returned count in main method. Display the two arrays by invoking a method named displayArray. 2 Sample inputs and their outputs are shown below: Input 8 numbers: 5 60 8 99 1 100 7 51 Count of numbers bigger than 50 is 4 Array1 is 5 60 100 51 66 Array2 is 60 99 100 51 Input 8 numbers: 80 19 91 150 37 23 50 49 Count of numbers bigger than 50 is 3 Arrayl is 80 19 91 100 37 23 50 49 Array2 is 80 91 100Problem: Write a method that will determine whether a given value can be made given an array of coin values. For example, each value in the array represents a coin with that value. An array with [1, 2, 3] represents 3 coins with the values, 1, 2, and 3. Determine whether or not these values can be used to make a desired value. The coins in the array are infinite and can only be used as many times as needed. Return true if the value can be made and false otherwise. Dynamic Programming would be handy for this problem. Data: An array containing 0 or more coin values and an amount. Output: Return true or false. Sample Data ( 1, 2, 3, 12, 5 ), 3 ( 4, 15, 16, 17, 1 ), 21 ( 1 ), 5 ( 3 ), 7 Sample Output true true true false
- In Java, create a program that gets user input to create an array of books. The length of the array should be determined by how many books the user enters. You may ask the user how many books they will enter. After all books have been entered by the user, invoke a method to display the contents of the array in a table. Each book will have a title, author, cover, pages, copyright (year), read time (float).In java, Write a method checks if a given matrix is a unit matrix. An N x N unit matrix is a matrix of N rows and N columns where all the diagonal elements are ‘1’s and all the remaining elements are ‘0’s. The method should take a 2D array of integers as argument and return a Boolean which is true/false depending on whether the matrix corresponding to the 2D array is a unit matrix or not. Test the method in the ‘main’ method. For problems asking for 'methods', you need to write the method, and the 'main' method which is used as a 'driver' to test the given method.Write a java program: Question 1 Write a program that allows the user to enter name and grade until "QUIT" is entered for name. The grade should be a number between 0 and 100. If the user input of a grade is not in this range, you should ask the user to re-input the grade. Store all the names in an array called names, and all the grades in an array called grades. Print out all the names and the corresponding grades. For Example, Input Enter name: Alice Enter grade: 90 Enter name: Bob Enter grade: 80 QUIT Expected output Name: Alice, Grade: 90 Name: Bob, Grade: 80
