Java Prims算法到Dijkstra算法

Java Prims算法到Dijkstra算法,java,algorithm,Java,Algorithm,我正在尝试使我现有的Prim算法实现保持与源的跟踪距离。因为prim和Dijkstra的算法几乎相同。我不知道我在哪里遗漏了什么 我知道问题出在哪里,但无法解决 这是我的代码,如何修改它以打印从源到所有其他顶点的最短距离。最短距离存储在名为:dist[]的数组中 代码: 包图; 导入java.util.ArrayList; 公共类Prims{ 静态int no_of_顶点=0; 公共静态void main(字符串[]args){ int[][]图={{0,2,0,6,0}, {2, 0, 3,

我知道问题出在哪里,但无法解决

这是我的代码,如何修改它以打印从源到所有其他顶点的最短距离。最短距离存储在名为:dist[]的数组中

代码:

包图;
导入java.util.ArrayList;
公共类Prims{
静态int no_of_顶点=0;
公共静态void main(字符串[]args){
int[][]图={{0,2,0,6,0},
{2, 0, 3, 8, 5},
{0, 3, 0, 0, 7},
{6, 8, 0, 0, 9},
{0, 5, 7, 9, 0},
};
顶点的数量=graph.length;
int[][]结果=新的int[没有顶点][没有顶点];
boolean[]访问=新的boolean[no_of_顶点];
int dist[]=新int[没有顶点];
