Write Java program
that takes an integer N from the command line and creates N by N boolean array a[][] such that a[i][j] is true if i and j are relatively prime (have no common factors) and false otherwise. print the output using * to represent true and a space to represent false and include row and column numbers.
(use sieving)
public class RelativePrime { public static boolean areRelativePrimes(int n1, int n2) { for (int i = 2; i < Math.min(n1, n2); i++) { if (n1%i == 0 && n2%i == 0) { return false; } } return true; } public static void main(String[] args) { if (args.length > 0) { int n = Integer.parseInt(args[0]); boolean[][] arr = new boolean[n][n]; for (int i = 0; i < arr.length; i++) { for (int j = 0; j < arr.length; j++) { arr[i][j] = areRelativePrimes(i, j); } } for (int i = 0; i < arr.length; i++) { for (int j = 0; j < arr.length; j++) { if (arr[i][j]) { System.out.print("*"); } else { System.out.print(" "); } } System.out.println(); } } else { System.out.println("Please provide a number from command line arguments"); } } }

Write a program FindDuplicate.java that reads n integer arguments from the command line into an integer array of length n, where each value is between is 1 and n, and displays true if there are any duplicate values, false otherwise. CODE IN JAVA and NO IMPORT STATEMENTS CAN BE USED
Using java write a program that takes a single, positive integer, n as a command-line argument. The program should then plot n evenly spaced points around a circle
Write a program Minesweeper.java that takes 3 command-line arguments M, N, and p and produces an M-by-N boolean array where each entry is occupied with probability p. In the minesweeper game, occupied cells represent bombs and empty cells represent safe cells. Print out the array using an asterisk for bombs and a period for safe cells. Then, replace each safe square with the number of neighboring bombs (above, below, left, right, or diagonal) and print out the solution. Try to...
Part 1: Write a C program that takes an integer command line argument n, spawns n processes that will each generate a random numbers between -100 and 100, and then computes and prints out the sum of these random numbers. Each process needs to print out the random number it generates. name the program 003_2.c
(Java) - Write a recursive program that takes array of number and an integer, and returns true if the integer is in the array or false if the integer is not in the array
Row and columns sum Create a java program that: Input: Receive as input in command line the sizes m and n of a two dimensional array Receive as input in command line the minValue and maxValue between which the random numbers will be generated for your two dimensional array Generate: Generate a two-dimensional with numbers between minValue and maxValue (inclusive) with the given size (m x n) Compute: Compute the sum for each row and store the results in a...
Write a program that takes a list of integer numbers from a user and creates a new sorted in ascending order list. As output you need to print original list and sorted one. use list and while python
Using Java. Write a program that creates a “triangular” two-dimensional array A of 10 rows. The first row has length 1, the second row has length 2, the third row has length 3, and so on. Then initialize the array using nested for loops so that the value of A[i][j] is i+j. Finally, print out the array in a nice triangular form.
Write a JAVA PROGRAM with function named getData() that takes a matrix A and an integer "row" as input parameters and returns an array containing all elements in the given row of A.
Write a Java program in Eclipse. . Write a Java program that: 1. Creates an array of 100 integers. Initialize the array to have all zeros. 2. Puts even numbers starting from 6 (excluding multiples of 12) into the first 50 slots of the array above. So numbers 6,8,10,14,16,18,20,22,26, etc. go into the first 50 positions in the array. Print the array. 3. Puts random numbers between 45 and 55 into the second 50 slots of the array above (second...
