1 .
Work through the “Hello, World!” Java tutorial to learn how to program Java to write a sentence to the screen. Start Exercise to cross reference the tutorial with the program. Find the online IDE Replit and establish an account. Research how to write “Hello World” to the screen in C++ and Python. Enter the code in Replit and write a report on your experiment pointing out some of the key concepts that you learned.
2 .
C++ has the concept of libraries of container classes, and both Java and C# have similar libraries of collections classes. These contain various types of data structures. We have examined the array; however, the array has limitations. Learn more about the container and collections classes, and look for examples of the patterns of data they are designed to represent and support. Contrast the various offerings with the plain array. Catalog the similarities and differences between the concepts in these three languages. Which of these libraries do you prefer? Why?
3 .
Study the most popular API library packages which enable multithreading for the languages of C, C++, and Java. In each of these languages, can you describe how multithreading works? Out of the routines you’ve learned so far, which of them are safe for multithreading? Which are not? Can all routines be made thread-safe?
4 .
WebAssembly is a new assembly programming language intended to execute high-performance code in the browser. Investigate the language features, and write a summary of the reasons for its use and the possible benefits and disadvantages for employing it for a simple web application.
