Each pond has a value v.Now Betty wants to remove some ponds because she does not having enough money. But each time if she removes a pond, she can only remove the ponds which is

Re-entry lock Reentrantlockjava.util.concurrent.lockThe framework in a Lock lock is an abstraction that allows the implementation of a lock to be implemented as a Java class, rather than as a language feature.This leaves space for a variety of Lock implementations that may have different scheduling algorithms, performance characteristics, or locking semantics.ReentrantLockClass is implemented Lock , it has the synchronized same concurrency and memory semantic

To change the table owner, I currently know two methods:
1. sp_changeobjectowner
Change the owner of objects in the current database.
SyntaxSp_changeobjectowner [@ objname =] 'object', [@ newowner =] 'owner'
Parameters[@ Objname =] 'object'
Name of the existing table, view, or stored procedure in the current database. The object data type is nvarchar (517), and no default value is available. The object can be defined by the existing object owner. The format is existing_owner.object.

owns all the members of the parent class.
1. Method rewriting (voerread)
Is occurring in the inheritance relationship. The methods that are overridden in the parent class and the methods that are rewritten in the subclass must have the same method name, the same return value type, and the same parameter list, the method to be rewritten in the subclass cannot have more strict access modifiers than the parent class.
The following is a simple example:
put, this means that this element needs to spend the cost to maintain itself and its content, rather than relying on the ancestor element to do this. Therefore, some elements have a layout by default. When we say that an element owns layout or gets layout, or an element has layout, we mean that its Microsoft proprietary attribute hasLayout is set to true. A layout element can be an element that owns layout
We often want to open a program without opening another instance. After exploration, we found that there are two solutions available: One is through the process, and the other is through the mutex class.1. Using mutex, mutex has an output parameter that can mark whether it is a newly opened Real column. We can use this parameter for processing.Using system;Using system. Threading;

This is a question you must decide.If we can find our target string in the CommandLine value, we will call the GetOwner method to find out the "owner" of the process (that is, the name of the account under which the script runs ):ObjProcess. GetOwner (strNameOfUser, strUserDomain)We need to use GetOwner to pass a pair of "Output Parameters ". The output parameter is the variable that the method will fill with a value (We will name the variable ourselves
enabled.
The difference between Strong and Weak:
Strong references hold objects, and weak references do not hold objects.
Strong references can release objects, but weak references cannot, because weak references do not hold objects. When a weak reference points to an object held by a strong reference, when the strong reference releases the object, weak references are automatically assigned nil, that is, weak references automatically point to nil.
Strong reference. For example:
