First, map set (set): not sorted, no duplicates.　　Instance Code :? 1 2 3 4 set name="images" table="IMAGES" lazy="true" > 　　key column="CUSTOMER_ID" /> 　　column="FILENAME" type="string" not-null="true"/> set>

The Java Collection framework is the foundation of the Java programming language and is an important knowledge point in the Java interview. Here, I've listed some important questions and answers about the Java collection.What is a 1.Java set frame?

First Lecture TreeSet1. OverviewTreeSet can sort the elements in the set set, in natural order.2. Demo CodeOutput Result:Summary: TreeSet will sort the elements naturally, with uppercase in front of lowercase.Second lecture TreeSet storing a custom

1. Basic IdeasMerge sort is an effective sorting algorithm based on merging operation, which is a very typical application of the partition method (Divide and Conquer). The ordered Subsequence is merged to obtain a fully ordered sequence, i.e., the

Merge sort is an efficient sorting algorithm based on the merging operation. This algorithm is a typical application of the method of division (Divide and Conquer).First consider how to combine the two ordered series. This is very easy, just from

Fast sequencing because of the efficiency of sorting in the same O (N*logn) of several sorting methods, it is often used as a face test.The basic idea of this method is:1. First, a number is taken from the series as the base number.2. The

There are eight types of classic sorting algorithms, namely:? Bubble sort? Select sort? Insert Sort? Merge sort? Hill sort? Quick Sort? Heap Sort? Base sortWhere bubble sort, select sort, insert sort are called three basic sorts.Although the time
