Exercise #1: Cumulative sum: Write a Java program that prompts the user to enter an integer number (n) that indicates the number of elements of an array (the maximum value for n is 100). Then the user enters n double numbers. The program creates another array of cumulative sums of the first array and outputs it. One decimal place should be used to output the cumulative array. Sample inputs/outputs: Enter the array size: 4 Enter the array elements: 5.0 6.5 7.3 10.2 Cumulative Array: 5.0 11.5 18.8 29.0 Enter the array size: 101 The maximum size is 100! Enter the array size: 5 Enter the array elements: 2.34 5.61 4.67 0.897 Cumulative Array: 2.3 8.0 12.6 19.6 20.4

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  9

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.

Design a program that asks the user to enter a store’s sales for each day of a 7 day week. The amounts should be stored in an array. Use a loop to calculate the total sales for the week, the average sales per day, and also display the list of values. This is for java.

Java program to check whether there is  zero (0) value or -1 , if its there then display true otherwise false. Consider the output as follow:
