Answer to Question #256413 in Java | JSP | JSF for dee

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:

1. Length         Width           Area
2. --------          --------         -------
3. 25               2.6              65.00
4. 18.2             4.9              89.18

Answer 1

import java.util.Scanner;


public class App {
	
	public static void main(String[] args) {
		Scanner keyBoard = new Scanner(System.in);
		System.out.print("Enter the number of rectangles: ");
		int n = keyBoard.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.print("Enter the length for Rectangle " + (i + 1) + ": ");
			length[i] = keyBoard.nextDouble();
			System.out.print("Enter the width for Rectangle " + (i + 1) + ": ");
			width[i] = keyBoard.nextDouble();
			area[i] = length[i] * width[i];
		}
		System.out.println("Length\tWidth\tArea");
		System.out.println("------\t-----\t----");
		for (int i = 0; i < n; i++) {
			System.out.println(length[i] + "\t" + width[i] + "\t" + area[i]);
		}


		keyBoard.close();


	}
