java - Overriding a method with generic Map parameter -


मेरे पास निम्न कोड है: 

  वर्ग कुंजी {- कुछ कार्यान्वयन} वर्ग ए { सार्वजनिक शून्य grpMap (ConcurrentMap & lt; key, list & lt; key & gt; keyList) {- कुछ कार्यान्वयन}} सार्वजनिक वर्ग बी विस्तारित करता है {- संपादित @ ओवरराइड - [कॉकॉ के उत्तर के बाद ["मेड" पूंजी का मामला] सार्वजनिक शून्य grpMap (ConcurrentMap & lt ; कुंजी, सूची & lt; की & gt; कुंजी लिस्ट) {- कुछ कार्यान्वयन}}   
 ऊपर कोड के साथ मुझे कक्षा बी में त्रुटि मिलती है  
 
 विधि grpMap (ConcurrentMap) टाइप बी को ओवरराइड करना चाहिए या एक सुपरटेप विधि को लागू करना   
 मेरी समस्या यह है कि मैं  वर्ग कुंजी, बी और सी  के रूप में घोषित नहीं कर सकता ये विरासत वर्ग हैं।  
 इस त्रुटि से छुटकारा पाने के तरीके पर कोई भी सुझाव?  
 संपादित करें ---  
 इस्तेमाल किया जेडीके संस्करण 1.6.43 है I ईक्लिपस का प्रयोग करते हुए जो स्वत: एनोटेशन उत्पन्न करेगा।   
 
 
 एनोटेशन  
  @ ओवरराइड   
 शॉ एलडी हो  
  @ ओवरराइड करें ????   
 इसके अलावा, आप आईडीई में जावा संस्करण की जांच करें - त्रुटि से छुटकारा पाने के लिए यह 1.6 या नए होना चाहिए।  
 ओपन  परियोजना गुण  - & gt;  जावा कंपाइलर  - & gt; अनुपालन का स्तर सेट करें  1.6  - & gt; ठीक है।

However, I want to take the first line and want to hold the actual date and then put it in the 'column' check and I also carry the last row and store it in 'Check Out' in the column call. Basically, for every day, I want to record the records in the user's time and want to take the time for each day. This is what I have done so far " return @RtnValue table (useridd integer, deptname varchar (max), emplname varchar (100), actualDate da...

javascript - Is there any way to add a new parameter to a function programmatically? -

Since I can set the number of expectations by calling a function its function.length Property, do I have to programmatically create the right number of parameters to include in that function at runtime? Example: var xyz = function (a, b) {}; Var BCD = function (A, B, C, D, E, F) {}; // vararg example var doc = document, func_length = xyz.length; Doc.xyz = (function () {returns function (A, B, C, D, E) works for one / but other is not}}}. Call (doctor); / * With `only two parameters ', like' Return function (A, B)`, if this function is used for `xyz` (although in this case 5 works fine), and return function ( If the function is used for 'BCD' (which does not work with only five parameters) with A, B, C, D, E, F) `6 / / Xyz.apply (blank, arguments) Think about ... but which logic ..? : // Returning function (A, B, C, D, E) does not support work with more than five parameters, which will be mostly class - hence my question / I also know very well That I use an obj...
