- (Electrical eng.) Write a program that declares three one-dimensional arrays named volts, current, and resistance. Each array should be declared in main() and be capable of holding 10 double-precision numbers. The numbers to store in current are 10.62, 14.89, 13.21, 16.55, 18.62, 9.47, 6.58, 18.32, 12.15, and 3.98. The numbers to store in resistance are 4, 8.5, 6, 7.35, 9, 15.3, 3, 5.4, 2.9, and 4.8. Your program should pass these three arrays to a function named calc_volts(), which should calculate elements in the volts array as the product of the corresponding elements in the current and resistance arrays (for example ,volts[1]=current[1]resistance[1]). After calc_volts() has passed values to the volts array, the values in the array should be displayed from inside main().In visual basic Print out the last value in a single-dimensional array.Problem2: 2D Arrays Define a 2D array using Java code that takes from a teacher the total number of rows and the total number of columns.

- Problem Description - JAVA PROGRAMMING Use a Two-dimensional (3x3) array to solve the following problem: Write an application that inputs nine numbers, each of which is between 1 and 10, inclusive. Display the array after the user inputs each value. Rotate/flip the array by changing places. Make the rows columns and vice versa. You have to move the elements to their new locations. Remember to validate the input and display an error message if the user inputs invalid data. Documentation and the screenshot(s) of the results. Example: 1 2 3 4 5 6 7 8 9 the result will be : 1 4 7 2 5 8 3 6 9Words: QUESTION 2 Write java program to create an array that read 5 double numbers.

- JAVA PROGRAM: Monkey Business A local zoo wants to keep track of how many pounds of food each of its three monkeys eats each day during a typical week. Write a program that stores this information in a two-dimensional 3 × 5 array, where each row represents a different monkey and each column represents a different day of the week. The program should first have the user input the data for each monkey, or use constant values rather than asking user for input. Then it should create a report that includes the following information: Display 3X5 array first. Average amount of food eaten per day by the whole family of The least amount of food eaten during the week by any one The greatest amount of food eaten during the week by any one Input Validation: Do not accept negative numbers for pounds of food eaten.Programming language: Java Write a program do the following: 1- ask student to enter name 2- ask student to enter the number of school subjects 3- Declare an array the same size as the number of school subjects. 4- ask the students to enter the marks in the array. 5- display the student name and the marks.Java code: declare an array of type Animal and create an array for this variable which can hold 5 animals.
