Write a program that creates a two dimensional array with 4 rows and 3 columns that contains the below numbers. Let the computer prompt you to enter these numbers. 8 6 1 7 3 0 2 5 9 5 6 7 After that, calculate and print the total and average of these values.
Write a program that: 1. Prompts the user to enter an integer representing the size of an array of integers 2. Fills the array with integers from the user input 3. Creates an array of integers to hold the differences between two consecutive elements, fills it accordingly and displays it Example: 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: 7 Enter 7 integers: 22 32 30 48 54 26 21 Differences: -10 -18 -6 28 2.
I have an array of the first 50 Fibonacci numbers in the picture. Your program should ask the user for a number between 5 and 21. Using that input as a location in the array, with that location and the next three locations (for example base, base+1, base+2 and base+3) you will multiply the outer values, base and base+3, (the first and last of the four). Do the same for the inner values (base+1 and base+2 multiplied) and then double that value. These two values form the two sides of a right triangle. Now find the hypotenuse. Remember the Pythagorean theorem, which says a2 + b2 = c2. Our two sides are a and b, so we square each of them (remember a * a = a2, so just multiply each value by itself) and add them together. That gives you c2. Now all you need do is take the square root of that sum. Given that the sqrt method normally returns a floating-point value (a double), we must force it to return a long integer for us in this case, so use the following line (with your own…
Program this in java:a. I input an array of integers: int[] arr = { 4, 100, 2, 50, 7, -45, -23, 84, 51, 120, 98, -72 }.b. Declare an integer variable that named "total".c. create a loop.d.1. The loop control variable value to be declared is 0. This will be represented by the variable "i" and it represents the index of the inputted array.e.2. The loop has a condition that if the current loop control variable value is greater than or equal to the size of the array minus the first item of the array, the loop will break.f.3. After the body or function is executed, the loop control variable is incremented by 2.g.4. The body of the loop has a conditional statement. if arr[i] is even, add it to total, else minus it to the total.g. After the loop breaks or finishes, display the value of the total.
You are give an array which contains the following integers : 9, 10, 12, 15, 7, 2, 1, 16, 18, 5, 6. Write a java program that will give you the product of this array

Input = 7.5 3.0 4.9 2.8 8.4 6.6 2.4 6.1 3.7 1.5 Output = 7.5 4.9 8.4 6.6 6.1 Input = 2.3 11.76 10.32 12.4 5.91 5.68 9.3 4.6 13.47 10.1 Output = 11.7 10.3 12.4 9.3 13.4 10.1 Requested files main.c 1 Binclude 2 3- int main(O 4 // Write your code here.. return(0);
4. Given an integer array of size 10, write a Java program to prompt the user to enter an integer value num and in the output print all numbers in the array greater than num. If no such number is present then print the message "No Results Found." in the output. Given Array: {12,67,45,89,94,56,78, 34, 47, 63}
Write a program that will input 5 numbers (double type) and display the numbers, their sum and average using one dimensional array. sample run: Enter the numbers: 1.0 2.0 3.0 4.0 5.0 The numbers are: 1.00 2.00 3.00 4.00 5.00 The sum is 15.00 The average is 3.00
Write a program in java using two dimensional arrays. You should prompt the user toenter the number of rows and columns for your matrix. You should then prompt the userto enter values for each element of the matrix. Once the user has provided all the values for matrix, you should print the matrix and transpose of that matrix. A transpose of a matrix converts rows to columns and columns to rows.Example:Output: This program transposes a matrix.Output: Please enter the number of rows:User enters 2Output: Please enter the number of columns:User enters 3Enter value for row[0] column[0]: 9Enter value for row[0] column[1]: 1Enter value for row[0] column[2]: 2Enter value for row[1] column[0]: 72Enter value for row[1] column[1]: 3Enter value for row[1] column[2]: 6The matrix you entered is:9 1 272 3 6The transpose of this matrix has 3 rows and 2 columns and the transpose is:9 721 32 6
Write a Java program that creates an array data of size 8, representing a binary number of 8 bits. The user must fill/enter the elements of this array only by inputting 0 or 1. If the user enters any different number, the program must display “Invalid data” message. If all entered digits are valid binary digits, the program must calculate and output the special decimal number represented by this binary number as shown in the below example: If the array data is 1 | 0 | 1 1 0 0 0 0 Result=1X2°+ 0X2'+ 1X2%+ 1X2'+ 0X2'+ 0X2°+ 0X2°+ 0X2 Result = 1 L3 0 + 4 + 8 + 0 + 0 + 0 + 0 = 13 Then the result is calculated by multiplying the value of the data array at each index with the result of 21 then adding all the answers. (shown in the above example) Sample runl: Enter the digits consisting of (0s or 1s): 2 5413257 Invalid data Sample run2: Enter the digits consisting of (0s or 1s): 1 111000 2 Invalid data Sample run3: Enter the digits consisting of (0s or 1s): 11110000 The number in decimal is…

C1. Write a Java program named Counter that asks the user to enter 15 real numbers and store them in an array. Then it should find and display how many numbers are below 25 in the array. The user should enter ten numbers in response to a message. A sample run of the program: Enter 15 real numbers: 55 101 -44 39 17 99 0 42 11 37 61 -51 78 213 55.75 There are 5 numbers are below 25 in the array.
