How can you eliminate thread blocking due to CPU resource shortage?

Problems with thread blocking due to CPU resource shortages can be solved in several ways:

• Code optimization: reduce the number of heavy computations, use more efficient algorithms.
• Using multithreading and asynchronous programming: distribute tasks among threads to avoid blocking the main thread.
• Thread Pool: limit the number of threads running simultaneously to prevent overload.
• Profiling and monitoring: identify bottlenecks and redistribute the load.

In Java, for example, you can use ExecutorService to manage a thread pool:

ExecutorService executor = Executors.newFixedThreadPool(4);
executor.submit(() -> {
    // heavy task
});
executor.shutdown();

This helps to avoid creating too many threads and blocking due to CPU contention.
