linked list program in java

recently in the training of ACM in C language to write a lot of linked list program. Because recently learning Java, so I want to write a list of Java program, the result encountered a lot of difficulties. The following article is

the listThere are at least three ways to traverse after JDK1.5: ForEach, iterator, for loop.Package Bupt.xiaoye.charpter2.list;import Java.util.arraylist;import Java.util.iterator;import java.util.List; public class Testfor {public static void Testforeach (List list) {Object Temp;for (object t:list) temp = t;} public static void Testfor (

) {System.out.println (current.data); Current=Current.next; } } //Reverse Print linked list Public voidReverseprint () {Node current= This. Tail; while(Current! =NULL) {System.out.println (current.data); Current=Current.prev; } } Public Static voidMain (String args[]) {mydoublelinklist linklist=Newmydoublelinklist (); Linklist.addhead ("AAAA");//System.out.println (Linklist.getdata (1));Linklist.addtail ("BBBB");//System.out.println

Summarize the problems that have been encountered in recent work.1. When int and Integer in Java are used for listThe relationship between the two is clear, int is the basic data type, the value is stored, and the Integer is the reference data type, which stores the address that points to the value. Integer is the encapsulation of int at the class level. Java then provides an automatic package unpacking mec

. Because the concurrent~~~ exception occurs. Therefore, in the iteration, only with the method of the iterator operation elements, but the Iterator method is limited, can only judge the elements, take out, delete the operation. If you want other operations such as add, modify, etc., use its subinterface, Listiterator. This interface can only be obtained through the Listiterator method of the list collection. */import java.util.*;p ublic class listdem

The linked list is an important data structure, which occupies a very important position in the program design. C and C + + language is the use of pointers to implement the linked list structure, because the Java language does not provide pointers, so some people think that in the
