- Write program java Create 2D array 4 *5. Ask the user to enter the number inside the array. Print the numbers organized by rows. Calculate the average for each row. Print the least average. Finally, create a method that receives a 2D array to print its elements reverse starting from the last element.Write a java program for the following: Create an integer array with 10 numbers. Apply the Linear Search method to find a target using Recursive method. Try to use a scanner to input the target value. Give different target values which shows both successful and not successful of searching method.Make sure each program has at least one method in addition to its driver method(main). Or use one driver main method and write method(s) for each of the program. Write a java program using a two dimensional array and store a 10X10 multiplication table results in it. Apply a nested loop to do this. Then display the content of this same array when the user press 5 on the keyboard. Write one method to populate the array and another method to display its content.
- Write a Java program to implement sequential search. Create a String array in main method and initialize it with 5 different names. Now take any name from the user, find whether that name is present in that array or not, and print the position of that name in the array if found. Write a search method to sequentially search the name from the array. Invoke the search method from the main method. The array and the name to be searched should be passed into the search method as parameters. Sample input & output:[Let’s assume that the 5 names are Diana, Becker, Ann, Eve, and Cory]Enter the name: CoryThe name is found at 5th position.Enter the name: Donald The name is not found.Now write a Java program to implement binary search for the above problem. [Hint: You can use equals() and compareTo() methods of String class.]Write a java program which: a. Create an array of length 10 b. Populate the array using method. Method should put the index value as element value. For example 0 1 2 3 4..... c. Replace every even number index with zero and odd number index with 1 using a method. Remember it should not overwrite the original array. You should then create a new array to manifest the replacement with 0 and 1.Write a Java method that returns the location of the largest element in a two-dimensional array. public static int[] locatelargest (double[][] a) The return value is a one-dimensional array that contains two elements. These two elements indicate the row and column indices of the largest element in the two-dimensional array. Write a Java test Program that prompts the user to enter a two- dimensional array and displays the location of the largest element in the array. Here is a sample run: Enter the number of rows and columns of the array: 3 4 Enter Enter the array: 23.5 35 2 10 |- Enter 4.5 3 45 3.5 -Enter 35 44 5.5 9.6 Enter The location of the largest element is at (1, 2)
- . Implement a program that randomly generates 10 integers from -100 to 100, stores them in a 1D array, and finds their maximum value. Calculate the execution time of finding a maximum. Repeat the test for 10,000 and 10,000,000 numbers. Provide your results in the form of a table below and provide a small summary. Implement a Java program that will populate a 5x5 matrix with randomly generated integers from 0 to 100. (1) print your matrix in a table form. (2) modify your code to multiply all even numbers by 10 and print the matrix. Your output of questions (1) and (2) should match the format of the following sample outputs:Use Java programming. Write the removeEvens() method, which receives an array of integers as a parameter and returns a new array of integers containing only the odd numbers from the original array. The main program outputs values of the returned array. Hint: If the original array has even numbers, then the new array will be smaller in length than the original array and should have no blank elements. Ex: If the array passed to the removeEvens() method is [1, 2, 3, 4, 5, 6, 7, 8, 9], then the method returns and the program output is: [1, 3, 5, 7, 9] Ex: If the array passed to the removeEvens() method is [1, 9, 3], then the method returns and the program output is: [1, 9, 3] import java.util.Arrays; public class LabProgram { public static int[] removeEvens(int [] nums) { /* Type your code here */} public static void main(String[] args) { int [] input = {1,2,3,4,5,6,7,8,9};int [] result = removeEvens(input); // Helper method Arrays.toString() converts int[] to a…Use C#. Chapter 6 discussed the predefined IndexOf() method of an array; the method takes two parameters, the whole array and an element to search. The method returns the index of the element if found, and -1 if not found. Now, you are asked to write a program that has a method FindMatch() that does exactly the same thing: 1) The Main() calls FindMatch(). 2) FindMatch() takes two parameters: 1) the whole array of integer test scores { 85, 98, 100, 73, 67, 82, 92, 87 }, and 2) an element to search from users input. 3) FindMatch() returns the index of element if found back to the Main(), and -1 if not found. The method should not use IndexOf() to do the search. 4) The program displays either the index or -1 in the Main(). Sample output (from Microsoft Visual Studio) as shown below
- Write a program that takes numbers from the user and places them into an array. After each new entry from the user, the program prints out the current array of numbers. Several rules must be followed: Each new number is checked and added to the array ONLY if it is larger than the number in the previous position in the array. This condition is not checked for the first number.In other words, the new number is rejected and nothing is added to the array if the entry is too-small. The new number is added to the array EXCEPT: when the user enters a number greater than 75, the number 0 is added to the array instead. when the user enters a multiple of 7 (and less than or equal to 75), the number 7 is added to the array instead. The program exits after 10 numbers have been placed into the array. Programming requirements: You must define and call at least one function. I recommend printArray(...) You must use at least one array. Assume the entries are integers Example Test Case:…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.Programming exercise (in java eclipse, please add comments for each step). Write a complete Java program named FindProduct that contains the following: a. A main method asks the user to provide the number of rows and columns for a 2-dimensional array of integers. b. A main method calls the getArray() method that creates the 2D array of specified size and populates it with random values from 0 to 100. c. A main method prints the elements of the 2D array created by getArray(). d. A main method calls the printProduct method that will: i. Receive the two-dimensional array as input ii. Calculate the product of elements in each row of the array iii. Display the product on the Console. The product of all elements in each row should be formatted as "Row 1 Product XXXX"
