Java集合 && Android提供的集合 LinkedList 底层结构是双重链表,线程不安全,可存储null,存储数据可重复,并且可用作堆栈,队列,双端队列 同步方式可以使用List list = Collections.synchronizedList(new LinkedList(...)); 增删要比ArrayList高效 ArrayList 底层是结构为可变数组,线程不安全,可以存储null,存储...
javaarrayslinkedlistgameimplementconvertscore 6th Dec 2016, 5:08 PM Rahaf Shiqdar + 1 To convert an array into a java.util.LinkedList we can use the java.util.Arrays class’s asList()method. The Arrays class in the java.util package provides a utility method to convert an array to a Li...

Where O2 means a O in square 2, etc.Now your linked list node class would have a node reference "next" which starts off life null. You can also have a reference to "previous" which makes it a doubly-linked list, which I think is how the java.util.LinkedList class is implemented....
