Solution

Here is a simple Java program that calculates the area of a rectangle:

public class Main {
    public static void main(String[] args) {
        // Declare variables for length and width
        double length = 5.0;
        double width = 4.0;

        // Calculate the area
        double area = length * width;

        // Print the result
        System.out.println("The area of the rectangle is: " + area);
    }
}

In this program, we first declare two variables length and width and assign them the values 5.0 and 4.0 respectively. Then we calculate the area by multiplying the length and the width. Finally, we print out the result using System.out.println(). When you run this program, it will print "The area of the rectangle is: 20.0".
