What’s new with the stop(), suspend() and resume() methods in JDK 1.2?

by

The stop(), suspend() and resume() methods have been deprecated in JDK 1.2.

In Java, the stop(), suspend(), and resume() methods were deprecated starting from JDK 1.2 and have been strongly discouraged for use. These methods were deemed problematic due to their potential to cause deadlock and other thread-related issues.

The recommended approach for controlling the execution of threads is to use the java.util.concurrent package and the java.lang.Thread methods introduced in later versions of Java. Specifically, the interrupt() method and the java.util.concurrent framework provide more flexible and safer mechanisms for managing thread lifecycle.

Here are some alternatives:

  1. Interrupt Mechanism: Use the interrupt() method to gracefully stop a thread. The thread being interrupted can check its interrupted status and decide how to respond.
  2. Concurrency Utilities: The java.util.concurrent package provides high-level concurrency utilities, such as ExecutorService, Future, and various thread-safe collections, which offer more control over thread execution.

It’s important to note that using stop(), suspend(), and resume() methods is not recommended due to their potential for causing thread hazards and deadlock situations. Instead, the modern Java concurrency model focuses on safer and more robust mechanisms for managing threads.
