SUMMARY

The discussion centers on creating a multithreaded program in either Java or C++ that manages file operations through five threads. Even-numbered threads are tasked with writing to a shared file, while odd-numbered threads delete from it. The goal is to cycle through these threads ten times without encountering race conditions, ensuring the final output file is accurate. The user seeks assistance in implementing this functionality as part of a final exam requirement.

PREREQUISITES
  • Understanding of Java or C++ threading concepts
  • Knowledge of file I/O operations in Java or C++
  • Familiarity with synchronization techniques to prevent race conditions
  • Basic understanding of multithreading design patterns
NEXT STEPS
  • Research Java synchronized blocks and methods for thread safety
  • Explore C++ std::mutex for managing concurrent access to shared resources
  • Learn about thread lifecycle management in Java and C++
  • Investigate the use of condition variables for thread communication
USEFUL FOR

This discussion is beneficial for students, software developers, and programmers who are working on multithreading concepts in Java or C++, particularly those focusing on file management and synchronization techniques.

Java or C++ - Threads HELP!

I need help with this program. I got five others to do and I won't have time to do it and it's apart of my final exam for next Tuesday, so here is my question I need:

Create 5 threads which share a file and
let "even" threads write to a file, and let "odd" delete from a file.
Cycle 5 threads for 10 times. Make sure final file gives correct output. (no race conditions)

Please help me out!
