Quick Answer
Two ways to create threads: extend Thread class and override run(), or implement Runnable interface and pass to Thread constructor. Prefer Runnable - it doesn't waste your single inheritance. Java 8+: use lambdas: new Thread(() -> doWork()).start(). Better yet, use ExecutorService to manage thread pools instead of creating threads manually.
Answer
Extend Thread or implement Runnable. Call start() to run thread asynchronously. Thread pools manage multiple threads efficiently.
