Write a Java program to implement the following 2D array named friends. Read the following instructions carefully and write the code. The above array shows the friend list of five persons Alice, Bob, Chuck, David and Eve. They are represented by index numbers 0, 1, 2, 3, and 4 respectively. You have to print i) List of friends of Alice, Bob, Chuck, David and Eve. ii) List of mutual friends of Alice & Bob, and Chuck & Eve. (DO NOT print the friends’ names and mutual friends’ names simply by println() method. You have to find the names programmatically.)

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

This is need in Java Declare an array named temperatures that can hold 10 doubles.

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}

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

How is this program written in java?

USING java: Create a simple Tic Tac Toe game designed for one player (against computer). you will need to create arrays and functions to complete this program. The first screen should ask the user for his name, print a welcome message, and display an empty 3x3 Tic Tac Toe board. Then, the program should ask the user to put the coordinates of his move. once the user enters the coordinates, the program should respond accordingly with a print of the user's move and the computer's move. this should go on until a winning pattern is found. Key steps: Game board is designed, user inputs taken and marked on the board, validate the inputs that no two inputs at the same place and out of range, check the winner/loser and complete the game.

Part 2: Coding 1. Write a complete Java program named FindAverage that contains the following: a. A main method that 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 printAverage method that will: i. Receive the two-dimensional array as input ii. Calculate the average of elements in this array iii. Display the average on the console. The average of all elements should be formatted as xxx.XX. Hint: you can print the 2D array at any point in the program using either traditional for loop, foreach loop or available methods in java.util package. e. Add comments to your program. Start your program with the following header: *** *** ***** /**** ***

Write an application that prompts the user to enter nine integers and then store those nine integers in an array. Display the integers from first to last, and then display the integers from last to first. You do not have to sort them, just display the order entered and the reverse order entered. (In JAVA)
