Answer to Question #257213 in Java | JSP | JSF for Silas Petrus

Question

Write a java program that specifies three parallel one dimensional arrays name length, width, and area. Each array should be capable of holding a number elements provided by user input. Using a for loop input values for length and width arrays. The entries in the area arrays should be the corresponding values in the length and width arrays (thus, area[i] = length [i]* width [i]) after data has been entered display the following output: Length Width Area -------- -------- ------- 25 2.6 65.00 18.2 4.9 89.18 Sample Run1 Enter the array size: 5 Enter the Length and Width for Rectangle 1: 25 2.6 Enter the Length and Width for Rectangle 2: 18 4.9 Enter the Length and Width for Rectangle 3: 100 3.27 Enter the Length and Width for Rectangle 4: 1.84 7.4 Enter the Length and Width for Rectangle 5: 56 9.5 Output1: Length Width Area -------- -------- ------- 25 2.6 65.00 18.2 4.9 89.18 100 3.27 327.00 1.84 7.4 13.62 56 9.5 532.00

Answer 1

import java.util.Scanner;


public class Main
{
	public static void main(String[] args) {
		System.out.println("Enter the size of the arrays: ");
		Scanner scan = new Scanner(System.in);
		int n = scan.nextInt();
		double [] length = new double[n];
		double [] width = new double[n];
		double [] area = new double[n];
		for(int i =0; i<n; i++){
		   System.out.println("Enter the Length and Width for Rectangle: "+ (i+1)); 
		   length[i] = scan.nextDouble();
		   width[i] = scan.nextDouble();
		   area[i] = length[i] * width[i];
		}
		System.out.println("Length   Width    Area \n"); 
		System.out.println("--------------------------------\n");
		for(int i =0; i<n; i++){
		   System.out.println(length[i]+"  "+width[i] +"  "+area[i]); 
		  
		}
		
	}
