Here’s the Java code:

In this code:

• We create a Java class named RectangleAreaCalculator.
• In the main method (the entry point of the program), we define two variables length and width to represent the dimensions of the rectangle.
• We calculate the area of the rectangle by multiplying the length and width variables and store the result in the area variable.
• Finally, we use System.out.println to display the length, width, and calculated area of the rectangle on the console.

To run this Java code:

1. Make sure you have the Java Development Kit (JDK) installed on your system.

2. Save the code in a file with a .java extension (e.g., RectangleAreaCalculator.java).

3. Open a terminal or command prompt and navigate to the directory where the Java file is located.

4. Compile the code by running the following command:

   bashCopy code

   javac RectangleAreaCalculator.java

5. After successful compilation, run the Java program with this command:

   bashCopy code

   java RectangleAreaCalculator

You should see the program output, which will display the rectangle’s dimensions and the calculated area.

This example demonstrates basic Java concepts, including variable declaration, arithmetic operations, and console output. It’s a simple starting point for learning Java programming.
