Learn tocreate a deadlock in Java programmatically, with an example. Also, learn todetect deadlock and how to solve a deadlock situationin source code. Generally, if the program is not synchronized properly and system resources are shared among threads, there is always a chance of a deadlock...
Lock Only What is Required: You should acquire lock only on the resources you have to work on, for example in above program I am locking the complete Object resource but if we are only interested in one of it’s fields, then we should lock only that specific field not complete object. ...
unable to proceed with their execution because each thread is waiting for a resource that is held by another thread in the deadlock cycle. As a result, the threads end up waiting indefinitely, leading to a complete halt in program execution. ...

In the Java programming language, every class implicitly or explicitly provides a hashCode() method, which digests the data stored in an instance of the class into a single hash value (a 32-bit signed integer). 1. 2. 3. 4. hashCode就是根据存储在一个对象实例中的所有数据,提取出一个32位...
In this blog, I will share how to detect deadlock situation using JDK standard tool jstack. First we have to write a Java program which will lead to Deadlock: package thread; public class DeadLockExample { /* * Thread 1: locked resource 1 ...

Deadlock in Threaddump Found one Java-level deadlock: === "PmdThread 1": waiting to lock monitor 0x0000025c81905b70 (object 0x000000041088f710, a net.sourceforge.pmd.lang.java.symbols.internal.asm.GenericSigBase$1), which is held by "PmdThread 16" "PmdThread 16": waiting to lock mon...
In this paper, we discuss how to dynamically detect dead locks in concurrent Java programs at run-time, and propose a representation of synchronization waiting state in an execution of a Java program, which is named the Java Thread-Wait-For Graph. We explicitly define all types of dead locks...
