Answer to Question #251742 in Java | JSP | JSF for guru

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

Answer 1

Source code

import java.util.Scanner;
public class Main
{
	public static void main(String[] args) {
	    Scanner in=new Scanner(System.in);
	    int n;
	    System.out.print("Enter the array size: ");
	    n=in.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 and Width for Rectangle "+(i+1)+": ");
		    length[i]=in.nextDouble();
		    width[i]=in.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]);
		}
	}
}

Output
