deep learning framework java

Deep Learning on Java multi-thread programming lock optimization and java multi-thread programming Body When programming in a concurrent environment, you need to use a lock mechanism to synchronize operations between multiple threads to ensure mutually exclusive access to shared resources. Locking may cause performance

[Java learning notes] Collection framework I, java learning notes Collection class: An object is used to encapsulate special data. An object needs to be stored if the number of objects is uncertain. The collection container is used for storage.Set features: 1. the container

The deep analysis of the seventh chapter class1. Inheritance1.1 class inheritance method: in Java, the child class inherits from the parent class by using the extends keyword in the declaration of the class. The general format is: [Class modifier] class 1.2 the inheritance and concealment of member variables: When you create a subclass based on a parent class, subclasses can inherit member variables and mem

It does not guarantee the set iteration sequence; in particular, it does not ensure that the

Enum class constructorsThe enum class should typically include specific enumeration objects, and it is convenient to add some descriptions to those enumerated objects. This allows you to use the constructor of the enumeration to describe the specific characteristics of the enumeration object. Normally the constructor is private, which is also normal, because the enumeration class itself cannot be modified. You can use ToString () to override the original method to make a custom description of th
