Consider a tree from the maze entrance to the shortest path near the point. The shortest path near the exit can be found by means of breadth traversal. The algorithm idea of this program originates from the Dijkstra algorithm of finding the shortest path near the other points in the graph. /* Maze Pathfinder III (Shortest path) * * /* Dijkstramaze.

Https://www.cnblogs.com/yw-ah/p/5830458.htmlJava four types of references include strong references, soft references, weak references, and virtual references.Strong references:The garbage collector will never recycle as long as the reference existsObject obj = new Object ();The corresponding object, such as Obj.equels (new object), can be obtained directly from obj.And so the Obj object is a strong reference
In the Java language, in addition to the basic data types, the others are object references to various types of objects, and in Java the references are divided into 4 classes based on the length of their life cycles.1 Strong referencesFeatures: Our usual typical code object obj = obj in new object () is a strong reference.
