Question
![Write code to complete doublePennies()'s base case. Sample output for below program with inputs 1 and 10:
Number of pennies after 10 days: 1024
Note: If the submitted code has an infinite loop, the system will stop running the code after a few seconds, and report "Program
end never reached." The system doesn't print the test case that caused the reported message.

Step 1 Introduction
Java is a high-level, class-based, object-oriented programming language. It is widely used for creating applications for the web, mobile, and desktop. Java is platform-independent, meaning it can run on any operating system, and is used for a wide variety of tasks including web and mobile application development, software development, game development, and big data analysis. Java is an easy-to-learn language with a large library of available tools and libraries, making it highly versatile and widely used.

(Assume the character variable is already declared, and give it a valid identifier name of your choosing, given that its purpose is to store the user’s response to the question “do you wish to input another set of data?”. You do not need to include any statements in the curly brackets for the loop.) (** How do I do this in c**)arrow_forwardFor Loop in Javaarrow_forward
