Java - How do I output the statement exactly as it shows? How can I get rid of the commas at the end? Don't get rid of each comma, just the ones at the end of the output. Write a program that lists all ways people can line up for a photo (all permutations of a list of Strings). The program will read a list of oneword names (until -1), and use a recursive method to create and output all possible orderings of those names separated by a comma, oneordering per line.When the input is:Julia Lucas Mia -1hen the output is (must match the below ordering):Julia, Lucas, MiaJulia, Mia, LucasLucas, Julia, MiaLucas, Mia, JuliaMia, Julia, Lucas.Mia, Lucas, Julia1 import java.util.Scanner;2 import java.util.ArrayList;NM4 in 610034 public class PhotoLineups {578910#2#99998=22**222*8========779#!11121314151617181920212324252630313334353637}32 public static void main(String[] args) {383940414243public static void printAllPermutations (ArrayList permList, ArrayList nameList) {if(nameList.isEmpty()) {44for(int i = 0; i newPerm = new ArrayList (permList);newPerm.add(nameList.get(i));ArrayList newNameList = new ArrayList(nameList);newNameList.remove(i);printAllPermutations (newPerm, newNameList);}}Scanner scnr = new Scanner(System.in);ArrayList nameList = new ArrayList();ArrayList permList = new ArrayList();string name;while(true) {name = scnr.next();if(name.equals("-1")) break;nameList.add(name);}printAllPermutations (permList, nameList);

Random Numbers: Most computer programs do the same thing every time they run; programs like that are called deterministic. Usually, determinism is a good thing, since we expect the same calculation to yield the same result. But for some applications, we want the computer to be unpredictable. Games are an obvious example, but there are many others, like scientific simulations. We have already seen java.util.Random, which generates pseudorandom numbers. The method nextInt takes an integer argument, n, and returns a random integer between 0 and n - 1. Assignment: For this assignment you will write a program in java to simulate a guessing game. Your program will generate a random number in a certain range (let the user define the range) and ask the user to guess what number it is. Give the user a certain number of tries while you narrow down the possibilities. For example, let's say the number generated is 67 and the user has 5 tries, this could be your program's output: This is a guessing…

Note: Please Answer in java only Ron has a very good knowledge of graphs and relationships. So he is given a question to solve it using a programming language. The coordinates of centres of these squares are (x1, a/2), (x2, a/2) and (x3, a/2) respectively. All of them are placed with one of their sides resting on the x-axis. You are allowed to move the centres of each of these squares along the x-axis (either to the left or to the right) by a distance of at most K. Find the maximum possible area of intersections of all these three squares that you can achieve. That is, the maximum area of the region which is part of all the three squares in the final configuration. Input 1 10 123 Output 0.00000

Java Programming: The program will figure out a number chosen by a user. Ask user to think of a number from 1 to 100. The program will make guesses and the user will tell the program to guess higher (h) or lower (l). Sample run of the program might look like below : Guess a number from 1 to 100. (here, the user is thinking of 81) Is it 50? (h/l/c): h Is it 75? (h/l/c): h Is it 88? (h/l/c): l Is it 81? (h/l/c): c Great! Do you want to play again? (y/n): y Guess a number from 1 to 100. (here the user is thinking 37) Is it 50? (h/l/c): l Is it 25? (h/l/c): h Is it 37? (h/l/c): c Great! Do you want to play again? (y/n): n our program should implement the binary search algorithm. Every time the program makes a guess it should guess the midpoint of the remaining possible values. Consider the first example above, in which the user has chosen the number 81: On the first guess, the possible values are 1 to 100. The midpoint is 50. The user responds by saying “higher” On the second…

Understanding ifStatements Summary In this lab, you complete a prewritten Java program for a carpenter who creates personalized house signs. The program is supposed to compute the price of any sign a customer orders, based on the following facts: The charge for all signs is a minimum of $35.00. The first five letters or numbers are included in the minimum charge; there is a $4 charge for each additional character. If the sign is made of oak, add $20.00. No charge is added for pine. Black or white characters are included in the minimum charge; there is an additional $15 charge for gold-leaf lettering. Instructions 1. Ensure the file named HouseSign.java is open. 2. You need to declare variables for the following, and initialize them where specified: A variable for the cost of the sign initialized to 0.00 (charge). A variable for the number of characters initialized to 8 (numChars). A variable for the color of the characters initialized to "gold" (color). A variable for the…
