Question

Write a test program called Main.java that prompts the user to enter width and height of the rectangle. The program should display the area, perimeter, color, name of rectangle and true or false.

Answer 1

A test program called Main.java could be written in Java, prompting the user for width and height, calculating the rectangle's area and perimeter, and displaying the details including its color and name followed by a boolean value.

Step-by-step explanation:

To write a test program in Java that prompts the user to enter the width and height of a rectangle and displays various properties, you’ll need to use classes, methods, and variables. The program should calculate the area and perimeter, and possibly assign and display a color and a name for the rectangle, as well as return a boolean value.

Here's a conceptual outline for Main.java:

import java.util.Scanner;

class Rectangle {
// Define attributes like width, height, color, name
// Define methods for calculating area and perimeter
}

public class Main {
public static void main(String[] args) {
Scanner scanner = new Scanner(System.in);
System.out.println("Enter the width of the rectangle:");
// Get width input
System.out.println("Enter the height of the rectangle:");
// Get height input

// Create Rectangle object and calculate area and perimeter
// Display the details
}
}

When comparing two areas, you calculate the ratio by dividing the area of the larger square by the area of the smaller square. If you have an area of 16 for the larger square and an area of 4 for the smaller one, the ratio would be 4:1.
