While a Java process has its own address space, a Java thread uses the process’ address space and shares it with other threads of that process. A thread can communicate with other threads of the same process using methods like wait(), notify(), notifyAll(). Global variables can also be...
We can provide the body to Thread in one of the two ways: first by subclassing a Thread class and overriding the run() method of thread, secondly by creating a Thread with Runnable object as its target. Body of a Thread Java threads are implemented by using Thread class which is the ...
maintaining, and observing high-throughput concurrent applications. This JEP enables server applications written in the simple thread-per-request style to scale with near-optimal hardware utilization, and it also lets existing code that uses thejava.lang.ThreadAPI adopt virtual threads with minimal chan...

security issues and provides isolation for customer workloads. This helps lower the risk due to side channel attacks. By running only a single thread per core, there is no sharing of the execution engine, registers, and L1/L2 cache between threads, which minimizes the attack surface for ...
Thread priority isn't very meaningful when all threads are competing for CPU. As an illustration, Figure 1 opposite shows the results of an experiment in which ten threads are run concurrently, one thread with each Java priority. Each thread sits in a CPU-intensive loop (continually a random...
threads that use shared resources for long times. Hence, the shared resources won't be available for other threads during Starvation. Another form of thread contention, livelock, is the undesired situation that occurs when threads simultaneously respond to each other's actions. In a way, threads...

OutofMemoryError is a type of error that occurs when a program or application attempts to allocate more memory than the available amount. This error occurs when the Java Virtual Machine (JVM) or another platform runs out of memory while trying to run an application. ...
Cached bean: At the end of the transaction, the instance stays in the ready state (cached) and the instance state is valid (ejbLoad called once on activation). Least database access. Exclusive access required. Multiple threads share same bean instance (poor performance). B Stale bean: At...
