The list box is generated by the Swing component JList, which occupies a fixed number of rows on the screen. To obtain the selected element in the list box, you only need to call getSelectedValuesList () to generate a string array with the selected element
The objects in the List are sorted in a linear order, and the order is determined by the pointers in each object. The list has several forms, which can be either single or double linked, either sorted or unordered, and can be either circular or non circular. The structure body and functions defined by are as follows:
typedef struct SINGLE_LINKED_LIST {Node * head;
Node * TAIL;
} SLL;

The fast ordering and sequencing of single linked lists are the same as the basic idea of fast sorting, which is also based on division, but there is a big difference:
a single linked list does not support access based on subscript. In fancier, the sorted list is split into 2 sub lists. For simplicity, select the first node of the list as the benchmark, and then
