- How to Create a Thread in JavaCreate threads by extending Thread, implementing Runnable or using a lambda, then start them with start(). Learn each way, plus Thread.ofPlatform.
- Daemon Threads in JavaDaemon threads are background helpers that don't keep the JVM alive. Learn setDaemon, isDaemon, when the JVM exits, and the risks of daemon threads.
- Interrupting a Thread in JavaInterruption is Java's polite way to ask a thread to stop. Learn interrupt(), isInterrupted(), InterruptedException and how to write stoppable tasks.
- Joining Threads in Javajoin() makes one thread wait for another to finish. Learn join(), join with a timeout, how it shows results safely, and how to wait for many threads.
- Performing Multiple Tasks with Multiple ThreadsRun different tasks in different threads, collect their results safely with join, and build a checkpoint that runs five simulated downloads in parallel.
- Multitasking: Multiprocessing vs MultithreadingMultitasking means doing several jobs at once. Learn process-based and thread-based multitasking, concurrency vs parallelism, and how Java uses both.
- Multithreading in JavaMultithreading lets one Java program do several things at the same time. Learn what a thread is, how it differs from a process, and why threads are useful.
- Calling Thread.run() Directly vs Thread.start()start() creates a new thread that calls run(); calling run() directly just runs the code in the current thread. See the difference in thread names and timing.
- Shutdown Hook in JavaA shutdown hook is a thread the JVM runs when the program is closing. Learn how to add one with Runtime.addShutdownHook, when it runs, and its limits.
- Can We Start a Thread Twice?No: calling start() a second time on the same Thread throws IllegalThreadStateException. Learn why, and how to run the same task again correctly.
