Variables Primitive Write a java program that asks the user to enter 3 integers. Add the integers and display “The total is “  the result Reference Write a java program that asks the user for their first name and last name. Display “Your full name is “  the first name and last name   Arrays One-dimensional Write a java program that creates an array of integers called numbers and contains five elements. Then use a for loop to print them out using println(). Two-dimensional submit your code for the total of rows and total of columns here

#include #include #include int main() { int i, j; printf("Columns | JIn"); for (i = 1; i< 4; ++i) { printf("Outer %6d\n", i); for (j = 0; j< i; ++j) { printf(" Inner%10d\n", j); } } /* heading of outer for loop */ /* heading of inner loop */ %3D return (0); } Create a new code modifying it to use "while loop" instead of the "for loop"

Validating User Input Summary In this lab, you will make additions to a Java program that is provided. The program is a guessing game. A random number between 1 and 10 is generated in the program. The user enters a number between 1 and 10, trying to guess the correct number. If the user guesses correctly, the program congratulates the user, and then the loop that controls guessing numbers exits; otherwise, the program asks the user if he or she wants to guess again. If the user enters a "Y", he or she can guess again. If the user enters "N", the loop exits. You can see that the "Y" or an "N" is the sentinel value that controls the loop. Note that the entire program has been written for you. You need to add code that validates correct input, which is "Y" or "N", when the user is asked if he or she wants to guess a number, and a number in the range of 1 through 10 when the user is asked to guess a number. Instructions Ensure the file named GuessNumber.java is open. Write loops…

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

class Main {             // this function will return the number elements in the given range             public static int getCountInRange(int[] array, int lower, int upper)             {                         int count = 0; // to count the numbers                         // this loop will count the numbers in the range                         for (int i = 0; i < array.length; i++)                         {                     // if element is in the range                                     if (array[i] >= lower && array[i] <= upper)                                                 count++;                         }                                                 return count;             }               public static void main(String[] args)             {         // array         int array[] = {1,2,3,4,5,6,7,8,9,0};                         // ower and upper range                         int lower = 1, upper = 9;                         // throwing an exception…

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
