It is then deleted, so that the root element = the last leaf node element, and then bubbles downward from the root element (Bubble-down) to adjust the heap. Bubbling down operation: each should be adjusted from the node, its left and right children in a total of three nodes select the smallest child nodes to exchange (if the smallest is itself without swapping), until the na

Java Get File size Today, when writing code to achieve the function of getting file size, there are two implementations, one is using the length () method of file, and the other is using the FileInputStream available () method, when InputStream does not perform a read operation , the size of the available () should be equal to the file size. However, when working with large files, the latter can cause prob

amount of space memory. When the request arrives, the buffer pool assigns an idle thread to the request, runs the request into the thread, and processes it. When a predesigned thread is running, a prefab thread is not enough, the thread pool can create a certain number of new threads to handle more requests. When the system compares space, you can also remove a part of the thread that is inactive.The advantage of this is that, on the one hand, the system resource overhead of frequently creating

In general, we write Java source code, with the Java compiler to compile the. class file, you will not encounter a failure to verify the situation, because the normal Java compiler will be careful to the generated code. So, one of the easiest ways to see the failure of valid

Java Small Example: the number of primes (prime numbers) refers to numbers that cannot be decomposed, except for 1 and no other number is divisible. Here is a small example of how to find all the primes within 100,000. NBSP The distribution of prime numbers is not regular, so to verify that a number is a prime, you must divide it with all numbers smaller than
