- Program64.javaWrite a program that demonstrates method overloading by defining and calling methods that return the area of a triangle, a rectangle, or a square. Program71.java Write a program that creates a 32-element array of random integers all from 1 to 100, inclusive. Then execute a custom method with the array as its only argument. The method should begin by using a loop to print the array elements in 4 rows and 8 columns, with all columns being five characters wide. Duplicates are okay. This same loop should determine how many integers in the array are odd numbers. After this loop ends, use this figure to declare a new array of integers named odds. Process the array again in the method, but this time with a foreach loop, and add the odd integers to the odds array. Return the odds array back to main. In main, report the size of the array and sort it ascending. Finally use a while loop to print the odd integers all on one line separated by spaces.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.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.

- Write a Java program tat prompts user for a list of integers with 0 as the last value.Save the values in an array. Assume there can be maximum 100 values. Theprogram should have the following methods:- A method that takes the array as parameter and updates each value in thearray to the square of the value.- Another method that takes the original and modified arrays as parametersand displays the original and the squared values.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 method that returns a new array by eliminating the duplicate values in the array using the following method header: public static int[] eliminateDuplicates(int[] list) Write a Java test Program that reads in ten integers, invokes the method, and displays the result. Here is the sample run of the program: Enter ten numbers: 1 2 3 2 1 6 3 4 5 2 -Enter The distinct numbers are: 1 2 3 6 4 5
- Write a Java program named RandomNumbers that creates a single-dimensional array of int of size 20 and initialize its elements with 20 random integer numbers (their range must be between 1 and 100 inclusive. Write statements in your program to display the array elements, and how many odd and even numbers are there in the array. For example, if the random numbers were stored in the array are: 83 48 89 66 40 94 31 31 12 45 45 87 10 24 78 2 28 31 52 46 Then the program should display: The random numbers are: 83 48 89 66 40 94 31 31 12 45 45 87 10 24 78 2 28 31 52 46 There are 8 odd numbers There are 12 even numbers An element in the array is a peak (max or min) if the elements before and after that element are greater than the element itself (min) or the elements before and after that element are less than the element (max). Write a method in your program called…Write a java application which initializes an array with ten random integers between 1 and 6. Write two methods: 1. arraySwap: this method should accept an integer array and swap the first and the last item. 2. findMinimum: this method should accept the array and return the minimum value of that array You should comment and follow javaDoc for both methods. Your main method should test each of these methods.QUESTION 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 91 100
- TableAA.java Write a program that will store a multiplication table in a 2-D array. The user will enter how many lines (rows) it will have. The table will be printed to the screen. (Make it look nice – consider using printf.) This program will contain a static method. This method will take in an integer (the user’s number) and it will return a 2-D array. The code inside of the method will create the array, fill it with all the appropriate values that one would expect in a multiplication table, and then return that filled array. In the main method, you will ask the user how many lines they want to see and then you will use your static method to get the array. Once you have the array back from the static method, use nested for loops to print it in table form. See samples on the following pages. Program only needs to run once. Add try/catches so the user can only enter positive integers (1 and higher).FOR JAVA Write a method that takes a one dimensional integer array and an integer, and returns the index of the integer in the array. If the integer is not in the array, your program must return -1. If there are multiple occurrences of that number, your program must return the smallest index. Repeat the second question, but if there are multiple occurrences of the number, your program must return the largest index instead of the small- est.Java: Write a method that is passed in a full array of integers and shifts all the data in the array up one index. The last value in the array should be stored at index 0 {5, 8, 9, 2, 1} becomes --> {1, 5, 8, 9, 2}
