What are Thread Scheduler and Time Slicing in java?

By | March 5, 2023

Thread scheduling is the process of determining which thread should execute when multiple threads are competing for CPU resources. In Java, the JVM uses a thread scheduler to schedule threads for execution. The thread scheduler assigns a priority level to each thread, and higher-priority threads are given preference over lower-priority threads.

Time slicing is a technique used by the thread scheduler to ensure that each thread gets a fair share of CPU resources. In time slicing, the CPU time is divided into small time slices, and each thread is given a time slice to execute. After the time slice expires, the thread is preempted and another thread is given a chance to execute.

In Java, the thread scheduler and time slicing are implemented by the JVM, which is responsible for managing the execution of threads. The JVM uses a variety of algorithms to schedule threads, including round-robin scheduling, priority scheduling, and fair scheduling. The scheduling algorithm used by the JVM depends on the operating system and the configuration of the JVM.
