ThreadFactory usage in Java

Question

Can someone briefly explain on HOW and WHEN to use a ThreadFactory? An example with and without using ThreadFactory might be really helpful to understand the differences.

Answer 1

ThreadFactory will be useful

• for setting more descriptive thread name
• to set thread daemon status
• for setting thread priority

You could use ThreadFactoryBuilder from google Guava lib to create ThreadFactory like this

ThreadFactory threadFactory = new ThreadFactoryBuilder()
        .setNameFormat("MyThreadPool-Worker-%d")
        .setDaemon(true)
        .build();
