क्या जावा वर्च के क्लास में एक कुंजी के लिए कई मान हैं?

सबसे पहले, डिक्शनरी क्लास के बारे में: उस वर्ग को चूक माना जाता है, दस्तावेज़ इसके बजाय मानचित्र का उपयोग करने की अनुशंसा करता है।

यह आप जिस संग्रह की मांग कर रहे हैं उसे एक बहुमप कहा जाता है। आप एक सूची के साथ स्वयं को लागू कर सकते हैं, लेकिन यह थकाऊ है।

आप अपाचे कलेक्शंस या Google कलेक्शंस से मल्टीमैट का उपयोग करना चाह सकते हैं। जब मैं व्यक्तिगत रूप से अपाचे संग्रहों का प्रशंसक हूं, तो वे वास्तव में जेनरिकों का समर्थन नहीं करते हैं, इसलिए Google multimap सुरक्षित हो सकता है।

I am on a shared hosting server, so please tell me some ways to use the code, because I can not make any modifications at the end of the server. If I expire the header, then there is no chance that if I make changes to the CSS, then the user will not be able to remove them immediately because CSS and other files have a fixed time limit (1 month, week ) Are cached for. Is Is there any harm to using PHP? $ time = time () + 3 * 24 * 60 * 60; // 3 day headings ('End:'. GMDAT ('D, D MYH: i: s \ g \ m \ t',

sql server - How can I determine which of my SQL 2005 statistics are unused? -

After a few years, one of my biggest databases has deposited 73 figures out of its largest tables. With Indexes, I can run many types of reports and queries, how often / heavily specific indexes are used. What is an equivalent for data? We are running SQL 2005. To make statistics automatically managed and honest, I would like to "update statistics", "create statistics" and There is no information about any management except "drop statistics" orders. In theory, UPDATE should handle the addition and removal of statistical data. In addition, I've never heard about the amount of storage or storage taking in large amounts, so I'm not sure whether there is any reason for the alarm or not. If you are seeing a potential problem, then I would suggest running an update before, if it does not clean it, it is leaving and then it appears to be safe operation (because it is the only query optimizer Is for). I will not leave "left" in the
