state variable

Whether an object needs to be thread-safe depends on whether it is accessed by multiple threads .When multiple threads access the same variable state amount , it is possible to make an error if the correct synchronization rules are not used.

Thread-related issues: a) security issue B) activity issues C) Performance issues The key to writing thread-safe code is to manage state access operations, especially access to shared and mutable states The main synchronization mechanism in Java

This article is for Java's Wait (), notify (), Notifyall () for a detailed analysis of the introduction of a friend that needs reference underWait (), notify (), and Notifyall () are all methods of Java.lang.Object:Wait (): Causes the current thread

11 Questions: Statistics on change patternsSICP the first chapter 1.2.2 tree recursion, there is a problem: given half a dollar, one-fourth dollars, 10 cents, 5 cents and 1 cents of coins, will be 1 dollars for change, altogether how many different

First we need to figure out what is called thread safety."Thread safety" means that when multiple threads access a class, this class behaves correctly regardless of the scheduling mode of the running environment or how those threads are alternately

Wait-notify sceneTypical wait-notify scenarios are generally related to the following two elements:1. Status variable (state Variable)when a thread needs to wait, it is always due to some condition that is not satisfied. For example, to populate the
