java - Can we create an Array of Generic class? -

संभव डुप्लिकेट:

मैं 10 तत्वों वाले स्टैक बनाना चाहता हूं, मैं जेनेरिक के साथ ऐसा करने की कोशिश कर रहा हूं मैं टाइप टी की एक स्टैक क्लास बनाकर शुरू किया, लेकिन जब मैं सामान्य प्रकार की सरणी को इन्स्तांत करने की कोशिश करता हूं तो मुझे संकलन त्रुटि मिलती है। 

  सार्वजनिक वर्ग स्टैक & lt; T & gt; {निजी टी [] Stk = नया टी [10]; }   
 क्या मैं यहाँ गलत कर रहा हूं?   
 
 
 आप ऐसा नहीं कर सकते कोड के बारे में कुछ गुप्त गोलियों का उपयोग किए बिना, और फिर भी आपको एक  असुरक्षित  कलाकार को अंत में करना होगा जो पहली जगह में सुरक्षित होने का प्रयास करने के पूरी तरह से पूरे कारण को नष्ट कर देता है।  
 इसका कारण यह है कि जावा में  type erasure  नामक कुछ है, कम्पाइलर सभी जेनेरिक सूचनाओं को फेंकता है और रनटाइम को पता नहीं है कि  T  क्या है  
 ऐसा करने का सबसे पसंदीदा तरीका यह है:  
  @SuppressWarnings ("अनचेक") स्थिर & lt; T & gt; टी [] नए अर्रे (कक्षा & lt; T & gt; प्रकार, पूर्णांक लंबाई) {वापसी (टी []) java.lang.reflect.Array.newInstance (प्रकार, लंबाई); }   
 यह सूची आवृत्ति के बारे में एक कोड  toArray ()  पर  सूची & lt; T & gt; > कार्यान्वयन हैक।  
 इस पर अधिक चर्चा के लिए

mysql - BLOB/TEXT column 'value' used in key specification without a key length -

-
I have developed an extension which works up to 1.6 on Magren (I'm trying Enterprise Edition, And I think the community is the same problem, because it is the same code). In my install script, I see the $ installer-> gt; CreateEntityTables ($ this- & gt; getTable ('alphanum / info')); The installation is done until it is not in the _text unit table. It crashed there! It turns out that when I log in to SQL and run it via PHPmyadmin, then this error is: Blob / Text column 'value' is used without the key 'key' . I saw the code there, and this is what is trying to create an index on the value column: -> addIndex ($ this- & gt; getIdxName ($ eavTableName, array ( 'attribute_id array (' attribute_id ',' value ')) - & gt; addIndex ($ this- & gt; getIdxName ($ eavTableName, array (' entity_type_id ' , 'Value')), array ('entity_type_id', 'value')) If there is no if statement is n...

javascript - What is an alternative to using getElementByClass for hiding multiple elements? -

-
I have a page with some links that I would like to be able to toggle with two buttons. It works with a link using getElementById, but I need to toggle some of those groups. I started with it, but it failed to work. I've heard that GetElementByClass has worked with everything but IE, but I'm using Opera 11.5 and it still does not work. I've searched a bit, but I'm new to some JavaScript and most of the explanation is not understood. Does anyone help me with a simple option, or can I help me fix the problem I've made? This is a test page I was using. & lt; Head & gt; & Lt; Script type = "text / javascript" & gt; Function hideNames () {document.getElementByClass ("WebName"). Style.display = "none"; } Function ShowName () {document.getElementByClass ("WebName"). Style.display = "inline"; } & Lt; / Script & gt; & Lt; / Head & gt; & Lt; Body & gt; & Lt; P class = "web...

c - Selecting a file randomly from a file system -

-
This question is related. I need to work on files and directories randomly as a file logic, such as rename, write, read etc. What I was planning to do, was to list all the files and directories along with their paths randomly to choose from this list. But, as the files and directories are created and destroyed in the actual file system, the list should also be updated. I am able to update the list and keep it inadequate in this way and it should also be atom so that the operation can not access any file later that was removed from the previous operation. Can you suggest that there is a different way of choosing files..to somehow integrate it with the file system ... but how do we know about the files? Thanks I'm Michael J. Barber's answer has found something particularly interesting, but due to my dragon ignorance I can not follow it completely You do not want to try to keep a list of files, when the file system is ok you should be able to correct it from C.
