get a runtime error called an EX Ception.Downcasting and the runtime checks require extra time for the running program and extra effort from the programmer.The solution is called a parameterized type mechanism. (Java se5,called generics)A parameterized type (compiler-level technology) is a class, the compiler can automatically customize to work with particular Types.Object Creation LifetimeWhen to destroy object?C + + takes the approach that control of efficiency are the most important issue,

its elements can be accessed efficiently and randomly, and the disadvantage is that the performance of inserting and removing elements at a specified location is slow. LinkedList is slower in random access, but it is more efficient to insert and remove elements at a specified location. 2. Set has three important implementations, respectively, Hashset,treeset,linkedhashset all implementation classes of the set interface ensure that their elements are not duplicat

Select the sort step:1. Locate the subscript of the smallest element in the array that participates in the traversal comparison;2. Swap the minimum element with the first element in the array that participates in the traversal comparison (if the first element is the smallest element, it will also be exchanged);3. If there are elements in the array that need to participate in the traversal comparison, jump to step 1, otherwise the sort ends.All of the sorts given in the

of ~2NLGN and constant additional space. Often used in embedded systems or in low-cost mobile devices (systems with very tight space), but many applications of modern systems seldom use it, because it cannot take advantage of caching. Array elements are rarely compared with other adjacent elements, so the number of cache misses is much higher than the algorithm that most comparisons make between adjacent elements, such as quick sort, merge sort, or even hill sort. On the other hand, the heap-im

Merge sort idea: Sort an array into two parts (using recursion), then merge the results together, merging the last two ordered arrays into a larger ordered array.Time complexity o (n) = NlognThe most appealing nature of merge sorting is that it guarantees that the time required to sort an array of any length n is proportional to the nlogn, and the disadvantage is that the extra space required is proportional to n.Merge sort is also divided into top-down sorting and bottom-up sorting methods:The

Down (LIFO) stack: an implementation that dynamically adjusts the size of the arrayImport Java.util.iterator;public class resizingarraystackAdvantages:Almost (but not useless) achieves the best performance for the implementation of any collection class data type:1. The time of each operation is independent of the collection size;2. Space requirements always do not exceed the set size multiplied by a constant.Disadvantages:Some push () and pop () operations adjust the size of the array, which is

operand.If the operands of an arithmetic or relational operation have multiple types, they need to be converted to the same type.A type conversion also occurs when a function is called.2. A named coercion type conversion has the following form:cast-nameWhere type is the target type of the conversion and expression is the value to be converted. If type is a reference type, the result is an lvalue. Cast-name is one of the static_cast, dynamic_cast, Const_cast and reinterpret_cast. Dynamic_cast su

Binary search tree: is a binary tree in which each node contains a key and a value associated with it, and each node has a key greater than the key of any node in its left subtree, which is less than the key of any node in its right sub-tree.The principle of each method of binary search tree is explained in detail in the code, the following is the code:/** * * @author seabear * Binary search tree * @param Copyright NOTICE: This article for Bo Master original article, without Bo Master permissio
