Java Virtual Machine specification has a very loose limit on the method area, and you can choose not to implement garbage collection, except that you do not need contiguous memory and can choose a fixed size or extensible, as with the Java heap.The memory recovery target for this area is primarily for the collection of constant pools and for unloading types.The OutOfMemoryError exception is thrown when the method area does not meet the memory allocation requirements. To run a constant-rate pool

In order to ensure the security of their computer data, now people can be said to be fair bet, at the beginning of the time we may be simply to set the password for their own computer, then we began to set the password for their own disk, and then set the password for the file, and now, we even learned to hide their files, or transform the file into other formats that people can't guess, so that our files are becoming more and more secure. Of course, everyone has a different habit of protecting
After repeated regions are added, you can add them in ascending order, without paging. on my webpage, add nbsp; repeated Regions nbsp; 50 messages are displayed nbsp; in ascending order nbsp; pagination is not allowed. The old information at the bottom of the page is at the top of the page. However, when more than 50 pieces of information are added, 1-50 pieces of information are displayed on the page. I don't want to display any old information when I add a new message. Thank you for adding

/ Method export information. Each method from the call to completion of the process corresponds to a stack frame in the virtual machine stack from the stack to the stack.(3) Local methods stack (native method stack):Similar to the virtual machine stack, the difference is that the virtual machine stack executes the Java method service, and the local method stack executes the local (native) method service.(4) Method area:Shared with the heap by all threads, used to store data such as class informa

Because of the growing size of Web applications, and more and more data, sometimes, because of a page at the same time too much data, resulting in the page is not beautiful, users will also be tired and difficult to operate. Therefore, this article will introduce the use of the hidden areas of the repeater control to achieve better data display results.
There are many ways to prevent data overload, such as using data paging method, or using the Maste
Talk about the younger generation of the JVM
1. Why are there young generations
We come first, why we need to divide the heap. Can not accomplish what he has done without being generational. In fact, there is no substitute, the only reason for generational is to optimize GC performance. First you think, if there is no generational, then all of our objects are in one piece, the GC when we want to find out which objects are useless, so that all areas o
Connectivity issues for OSPF areas
If this happens: a normal area is not connected to area 0, you can use the following three methods to resolve it.
1 the different OSPF process on ABR, carry on the redistribution between the OSPF.
For example: R1 's S0 port is in area 1, the process number is the 10,S1 port in area 2, the process number is 20, and then the redistribution
