how "break" calculation

[racewithferrari]

My problem is that my total is coming as a cumalative, it is adding all the States population, so how do I break the calculation when another State starts, suppose NY state start at row = 5, so it should add till that. And for NJ it should add from row6 to row 9, and same for CT state.

import java.io.*;
import java.text.*;
import java.util.StringTokenizer;

public class statepop {

 public static void main(String[] args) {
   
   // System.out.println("Memo# 458");
    DateFormat dateFormat = new SimpleDateFormat("MM/dd/yy");
            java.util.Date date = new java.util.Date();
            String datetime = dateFormat.format(date);
            System.out.println(" \t\t\t\tDate " + datetime);
                   
   System.out.println("**--------------------------------------------------** ");
    System.out.println("State \tCity \tM Pop.\tF Pop. \tChild Pop.");
   System.out.println("**--------------------------------------------------** ");
   try {
   FileInputStream fstream =
 
  new FileInputStream("C:\\Users\\FK\\Desktop\\states.txt");
   // Get the object of DataInputStream
   DataInputStream in = new DataInputStream(fstream);
   BufferedReader br = new BufferedReader(new InputStreamReader(in));
   String strLine;
 int rows = 0;
   float totalma = 0;
   float totalfe = 0;
   float totalch = 0;
  // float avg;
  // float avg1,sum;
  //double gt;
 //  double tax;
   double malep = 1;
   double femalep = 1;
   double childp=1; 
 
   //Read File Line By Line
   while ((strLine = br.readLine()) != null) {
    rows++;
    // Print the content on the console
    StringTokenizer Tok = new StringTokenizer(strLine, ",");
    int currentToken = 0;
    int totalTokens = Tok.countTokens();
    while (Tok.hasMoreElements()) {
     currentToken++;
     String tokenValue = Tok.nextToken();
     if (currentToken == 3) malep = Double.parseDouble(tokenValue); 
     if (currentToken == 4) femalep = Double.parseDouble(tokenValue); 
     if (currentToken == 5) childp = Double.parseDouble(tokenValue);
    

     System.out.print(tokenValue + "\t");
     if(currentToken==totalTokens){
       
     totalma+=malep;
      totalfe+=femalep;
      totalch+=childp;
      if(rows ==5){
       
      System.out.println("\n___________________________________________________________");  
       System.out.printf("\nTotal\t\t%.0f", totalma);
   System.out.printf("\t%.0f", totalfe);
   System.out.printf("\t%.0f", totalch);
        System.out.println("\n___________________________________________________________");}
      
       if (rows ==9){
        System.out.println("\n___________________________________________________________");
       System.out.printf("\nTotal\t\t%.0f", totalma);
   System.out.printf("\t%.0f", totalfe);
   System.out.printf("\t%.0f", totalch);
   System.out.println("\n___________________________________________________________");}
     // System.out.print(malep);
    //  System.out.print(femalep);
    //  System.out.print(childp);
     }
    }
  System.out.print("\n");
   }


    System.out.println("xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx ");
   
 
    System.out.printf("Total\t\t%.0f", totalma);
   System.out.printf("\t%.0f", totalfe);
    System.out.printf("\t%.0f", totalch);
    
   
   
   
    //Close the input stream
    in.close();
   } catch (Exception e) { //Catch exception if any
     System.err.println("Error: " + e.getMessage());
   }
 }
}

states.txtdata file attached where the program reads it.

You should create a class that holds one state's information in it, and have an ArrayList of these objects. Then when you read each line, first extract the state, see if you already an object for this state in your list, if not create one, and if so, add your numbers to it.

Also I'd recommend you use some kind of layout for your code or an IDE formatter and also use methods. That code is pretty horrible to look at like this.

He's obviously running his code through a creative indentation format utility, perhaps to obfuscate it and protect the innocent.

I occasionally look back at code I wrote in my first year of uni (I've only been working as a programmer for 6 months so still only 4 years ago) and thinking what the hell is this. Which someone had slapped me in the face, gave me an IDE and told me to format it properly.
