Pseudocode

[zhamri]

Instruction

Below is the Pseudocode to calculate the perimeter of a rectangle.

Start  

1. Output "Enter rectangle length: "  
2. Input length   
3. Output "Enter rectangle width: "  
4. Input width   
5. Calculate perimeter = 2 x(length + width)  
6. Output perimeter    

End  

Write a Java program to calculate the perimeter.

Submission

1. Java source code
2. Screenshot the output
