captured instead of its value when the delegate instance is created. The lifetime of the captured variable is extended, at least as long as the delegate that captures it. Multiple delegates can capture the same variable ... ...... But inside the loop, the same variable declaration actually refers to a different "instance" of the variable. The variables created in the declaration of the For Loop are valid only during the duration of the loop-not instantiated at each iteration of

, the waking thread must be the thread that waits the longest. However, in Java technology, this is not guaranteed.Note that notify () can be called regardless of whether the thread is waiting. If you call the Notify () method on an object, and there are no threads in the lock flag waiting pool for the object, then the Notify () call will have no effect.In Java, multithreading is a magical theme. It is "magical" because the running results of multi-threaded procedures are unpredictable, but we c

Lab 1 recursive exercise I. Tutorial Purpose 1. Familiar with the use of development tools. 2. Grasp the implementation idea of recursion. Ii. experiment content 1. output the full arrangement of N integers. 2. Output all subsets of N integers. First, install the development tool: Visual c ++ 6.0 (based on your preferences) Baidu search downloads:

1. Classes and objects 1.1 concepts of classes and objects Class: the object type, which is different from the basic data types such as int, because the class has behavior; it can also be said thatA set of objects with the same features and behaviors.Objects: objects are objects that you can see and touch. They are real objects with the same features andBehavior objects can be abstracted into classes.1.2 Definition class syntax [Modifier] class classn
