After 1.NotifyThread calls the Notifyall () method, Waitthread does not return immediately from the Wait () method.Because of this time Notifythread did not release the lock. 2. Program 61 Line,notifythread the first release of the lock, however waitthread do not make up, and did not grab this lock. Still in blocked state. 3. Until 67 lines.

A more straightforward approach is to implement directly through the Apply () function. > Apply (cttab, 1, sum) no not sure Yes 2 1 A more straightforward approach is to use the function addmargins (), which adds boundary values, to directly increase the boundary values of two dimensions. > Addmargins (cttab) voted.for.xvote.for.x No yes Sum no 2 0 2 not

which are contained in the array returned by the ChildNodes property.However, each node has a NodeType property. The NodeType attribute has a total of 12 desirable values, but only 3 of them have value: The NodeType attribute value of the element node is 1, the property node's NodeType property value is 2, and the NodeType property value of the text node is 3.If you want to change the value of a text node, use the NodeValue property provided by the DOM.Array element Childnodes[0] There is a mor

Compression script:The so-called compression script, refers to the script file unnecessary bytes, such as spaces and comments, all deleted, so as to achieve the purpose of "compressed" file. Fortunately, there are many tools that can do it for you. Some refiners will even rewrite some of your code, using shorter variable names to reduce the overall file size. The streamlined code, while not easy to read, can drastically reduce file size. In most cases, you should have two versions, one working

adept at handling repetitive tasks. It is easy to traverse a long list with a while or for loop.Responding to EventsCSS provides: pseudo-class attributes such as hover allow us to change the style based on the state of the HTML element. The DOM can also respond to changes in the state of an HTML element through events such as onmouseover. So when to use: hover, when to use onmouseover?The simplest answer is to choose the easiest way to achieve it. For example, if you just want the link to chang

1. A document is a tree of nodes2. Nodes are divided into different types: element nodes, text nodes, attribute nodes, etc.3. Each node is an object, and the atom of the DOM is an element node4.getElementById returns an object that corresponds to a specific element node in the document5.getELementsByTagName and Getelementsbyclassname return an array of objects that correspond to a specific set of ELEMENT nodes in the document, respectively.The 6.typeof operator can tell us whether its operand is

, this usage is not a good habit and is not recommended for everyone to use. Essentially, when you create an associative array, you create an array object's properties. In JavaScript, all variables are actually objects of some kind. For example, a Boolean value is an object of type Boolean. In the above example, you are actually adding the name, year, and living three properties to the lemon array. Ideally, you should not modify the properties of an array object, but you should use a generic obj

visibility, if a read lock has been acquired by multiple threads, where any thread has successfully acquired a write lock and updated the data, its update is not visible to other threads that acquire a read lock.NO13:NO14:Condition defines a wait/notification type of method that, when called by the current thread, needs to get the lock associated with the condition object in advance. The condition object is created by the lock object (called the Newcondition () method of the lock object), in ot

At the same time, I changed my name to the studio. The reason for renaming is that we have three considerations: 1. Serving the interview service cannot be our ultimate or major goal. 2. I would like to answer one interview questio
