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. a) 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
Write a program in JAVA to input the number of elements in an array, also input the values in the array from the console. Replace all those elements which are even and greater than 5, with -99. Print the final array. Constraints: The array should initially not contain -99. The value of the number of elements should not be greater than 50.
In Java Create a simple program that asks the user for a row and column size for a 2-D integer array, then haveThe program create such an array. At this point this array’s cells should be filled with zeros sincenothing has been done to change the cell values.Next, have that program dynamically adapt to the sizes of the array (that were provided by the user) andfill the array with numbers ascending from 1 → n (n being the number of the nth cell in that 2-D Arraydepending on the size). Please then print the array out. Remember, you cannot just print an arrayout, you have to use loops and print each cell individually.Please refer to the sample output below for visualization and match its style.As always:• Remember, the class name should be Lab8B.• The user input is indicated in bold.Sample Output #1:Please enter the number of rows: 4Please enter the number of columns: 4I have 4 rows and 4 columns. I need to fill-up 16 spaces.The 4x4 array:1|2|3|4|5|6|7|8|9|10|11|12|13|14|15|16|Sample…
Write a Java program to find continuous sub array of the given array whose sum is equal to a given number. For example, If {12, 5, 31, 9, 21, 8} is the given array and 45 is the given number, then you have to find continuous sub array in this array such that whose elements add up to 45. In this case, {5, 31, 9} is such sub array whose elements add up to 45.
Write a Java program that would resemble banking transactions of deposits, withdrawals, bank to bank transfers, and interest computations. A transaction input window is to be used in entering the account number, transaction code, and amount. Search a 2d-arraylist containing account number and the current balance, and then do the appropriate update on the 2d-arraylist depending on the transaction code. If the transaction code is “D”, update the current balance by adding the amount; if “W”, update the current balance by subtracting the amount from the current balance provided that withdrawal transaction is allowed (current balance must be greater than the amount to be withdrawn, and the resulting balance must not be less than 500). Display the updated 2d-arraylist before exiting the program. Design your own input/output windows. ( USE OOP CONCEPT AND JOPTION)
How to write a program in java that ask the user to input an int size value into a 2d array, then output a table of random 0 and 1 of that size (table must be a perfect square), then output the fraction of your array that is ones and the fraction that is zeros, then output the sum for each row, the sum of colunms and which row and colunm have the largest sum, then determine if the largest row sum is greater than the largest column sum or vice versa, then output the sum of the diagonal(the diagonal starting at location [0][0] and going down to [N-1][N-1] for an array of size N) and determine if the diagonal sum is greater or equal to the largest row sum and greater than or equal to the largest column sum? output should look similar to screen shot

Write a java program that:1. Prompts the user to enter an integer representing the size of an array of integers2. Fills the array with integers from the user3. Creates an array of integers to hold the differences between two consecutive elements, fills it accordingly and displays itExample: In the below sample run, the array is of size 7 and is filled using values entered by the user with the below integers. The array of differences contains -10 which is (22 – 32), 2 which is (32 – 30), -18 which is (30 – 48) and so forth.Sample Run:Enter the size of the array: 7Enter 7 integers: 22 32 30 48 54 26 21Differences: -10 2 -18 -6 28 5
Write a Java code # Resistor ColorResistors have color coded bands, where each color maps to a number. The first 2 bands of a resistor have a simple encoding scheme: each color maps to a single number.These colors are encoded as follows:- Black: 0- Brown: 1- Red: 2- Orange: 3- Yellow: 4- Green: 5- Blue: 6- Violet: 7- Grey: 8- White: 9Mnemonics map the colors to the numbers, that, when stored as an array, happen to map to their index in thearray: Better Be Right Or Your Great Big Values Go Wrong.More information on the color encoding of resistors can be found in the [Electronic color code Wikipedia article]# Running the testsYou can run all the tests for an exercise by entering $ gradle test in your terminal.## SourceMaud de Vries, Erik Schierboom [https://github.com/exercism/problem-specifications/issues/1458] Consider the structure that the code must have; it is given in the picture
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"} in java
Write a java code that computes the alternating sum of all the elements in an array. For example, if your program has an array with these elements. 1 4 9 16 9 7 4 9 11 It will compute: 1 - 4 + 9 - 16 + 9 - 7 + 4 - 9 + 11 = -2
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.
