Thread: Problem with For Loop

Here is the code

for (int g=1;g < V+1 ;g++) {
                        System.out.println("For LOOP"+g);
 
                        if (point1 != g){
                            dis = prim.GetDis(point1, g);
                            System.out.println(point1);
                            System.out.println("g "+ g);
                            System.out.println(dis);
                            if (dis > 0){
                                g = point[p];
                                p++;
                            }else{}
                        }else{}
}

the output is
For LOOP1
3
g 1
50
For LOOP1
3
g 1
50
For LOOP1
3
g 1
50
For LOOP1
3
g 1
50
For LOOP1
3
g 1
50

I don't know why it continue loop for 1, can you please help me to find out the problem?

Step through your code.... Add print statements if you need to.

Get rid of those "else{}" they are unneeded

Check out the value of point[p] when you are assigning it to g, if point[p] is always 1, you will see the behavior you are seeing now.

if (dis > 0){
     g = point[p];
     p++;
}
