    Default Prim's MST

    Hi, I am doing an assignment that requires us to do a reverse delete and prim's on a graph. I have already completed the reverse delete and most of the prim's, I just can not figure out how to do a check for cycles. Can anyone point me in the right direction? I'm not looking for code, just some advice. Here's my Edge class:

    package assignment7;
    public class Edge {
        private int weight;
        private char v1;
        private char v2;
        private boolean check;
        public Edge(int weight, char v1, char v2){
            this.weight = weight;
            this.v1 = v1;
            this.v2 = v2;
            this.check = false;
        }
        public char getV1(){
            return this.v1;
        }
        public char getV2(){
            return this.v2;
        }
        public int getWeight(){
            return this.weight;
        }
        public boolean checkIt(){
            return this.check;
        }
        public void change(){
            this.check = true;
        }
    }


    The check was used in reverse delete if the edge was visited and could not be deleted. My MST is contained in a Vector<Edge>(suggested by the professor). Thank you for your help.
