Wrong count i in for loop in Java code - Prim's algorithm-CodePudding

I have a big problem. I am a beginner in Java. Please help me, thanks. This part of code is a Prim's Algorithm.

The code is:

for (int i = 1; i < graph.getNumOfNodes(); i  ) {
    double distance = ((int)graph.getEdges(i) - 8);

    if (graph.getEdges(i) <= 8){
        System.out.println("Day "   i   ". "   "Number of hours worked "   (int)graph.getEdges(i)   "/8 per day. Finished kilometers: "   (int)graph.getEdges(i) );

    } else if (graph.getEdges(i) > 8) {
        System.out.println("Day "   i   ". "   "Number of hours worked 8/8 per day. Finished kilometers: 8. "   "Missing to complete: "   (int)distance);
        System.out.println("Day "   i   ". "   "Number of hours worked "   (int)distance   "/8 per day. Finished kilometers: "   (int)distance);
    }
}

Now output: the Day 3 is twice but I need the second day 3 to be day four and the rest will be one larger.

Day 1. Number of hours worked 2/8 per day. Finished kilometers: 2
Day 2. Number of hours worked 7/8 per day. Finished kilometers: 7
Day 3. Number of hours worked 8/8 per day. Finished kilometers: 8. Missing to complete: 2
Day 3. Number of hours worked 2/8 per day. Finished kilometers: 2
Day 4. Number of hours worked 5/8 per day. Finished kilometers: 5
Day 5. Number of hours worked 4/8 per day. Finished kilometers: 4
Day 6. Number of hours worked 3/8 per day. Finished kilometers: 3
Day 7. Number of hours worked 1/8 per day. Finished kilometers: 1
Day 8. Number of hours worked 8/8 per day. Finished kilometers: 8
Day 9. Number of hours worked 5/8 per day. Finished kilometers: 5
Day 10. Number of hours worked 4/8 per day. Finished kilometers: 4
Day 11. Number of hours worked 3/8 per day. Finished kilometers: 3
Day 12. Number of hours worked 8/8 per day. Finished kilometers: 8

I would like the output like this:

Day 1. Number of hours worked 2/8 per day. Finished kilometers: 2
Day 2. Number of hours worked 7/8 per day. Finished kilometers: 7
Day 3. Number of hours worked 8/8 per day. Finished kilometers: 8. Missing to complete: 2
Day 4. Number of hours worked 2/8 per day. Finished kilometers: 2
Day 5. Number of hours worked 5/8 per day. Finished kilometers: 5
Day 6. Number of hours worked 4/8 per day. Finished kilometers: 4
Day 7. Number of hours worked 3/8 per day. Finished kilometers: 3
Day 8. Number of hours worked 1/8 per day. Finished kilometers: 1
Day 9. Number of hours worked 8/8 per day. Finished kilometers: 8
Day 10. Number of hours worked 5/8 per day. Finished kilometers: 5
Day 11. Number of hours worked 4/8 per day. Finished kilometers: 4
Day 12. Number of hours worked 3/8 per day. Finished kilometers: 3
Day 13. Number of hours worked 8/8 per day. Finished kilometers: 8

CodePudding user response：

I would just add a counter to count the extra days as follows:

extraDays = 0
for (int i = 1; i < graph.getNumOfNodes(); i  ) {
    double distance = ((int)graph.getEdges(i) - 8);

    if (graph.getEdges(i) <= 8) {
        System.out.println("Day "   (i   extraDays)   ". "   "Number of hours worked "                   (int)graph.getEdges(i)   "/8 per day. Finished kilometers: "   (int)graph.getEdges(i) );
    } else if (graph.getEdges(i) > 8) {
        System.out.println("Day "   (i   extraDays)   ". "   "Number of hours worked 8/8 per day. Finished kilometers: 8. "   "Missing to complete: "   (int)distance);
        extraDays  = 1
        System.out.println("Day "   (i   extraDays)   ". "   "Number of hours worked "   (int)distance   "/8 per day. Finished kilometers: "   (int)distance);
    }
}
