Sure, here is a simple Java program that calculates the area of a rectangle:

```java
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".
