Note: The following source code is based on jdk1.7.0 _ 11
The Set set is actually an encapsulation of the map set. The map set stores key-value pairs, So we hide the values and do not expose them to the outside world. This forms the Se

You can use the following code to set the GPRS contact:

recommendation 18, a reason why the foreach loop cannot replace the for loop is that the set itself is added or deleted during the iteration process. Porting this scenario to a multi-threaded scenario is the focus of this suggestion: Ensure the thread security of the set. Collection thread security means that when a live deletion element is added to multiple threads, the threads must be synchronized.

Copy Code code as follows:
/**
* Each is a collection iteration function that takes a function as a parameter and a set of optional parameters
* This iterative function computes each element and optional parameter of the collection in turn, and returns the computed result set

almost no article about how to do this thing. The GDB code was turned over and no hardware breakpoints were seen in arm (the GDB version used was too old). Later a multi-party search, find some information, recorded in the following:

Here is an example of an array, showing some common LINQ operations.
Copy Code code as follows:

Int[] A = {1, 2, 3, 4, 5, 6, 7};
Int[] B = {4, 5, 6, 7, 8, 9, 10};
Int[] C = {1, 2, 3, 3, 4, 1, 2, 4, 6, 1, 6, 5};
Intersection
var fuck = A.intersect (b);
and set
var shit = a.union (b);
