Addition table gaava et arraylist

Question

J'ai ce programme et je veux recueillir des valeurs dans ArrayList operatCible et les valeurs dans le tableau employeeYearsOfService et je veux stocker le résultat dans HashMap<String,integer> qui contient RowKey et le résultat.

Je ne sais pas comment le faire. Ce que je veux

code

public class collaborativAlgorithme { 

    Table<String, String, Double> employeeYearsOfService = 
    HashBasedTable.create(); 

    public static void main(String[] args) { 
    List<Double> operatCible = new ArrayList<Double>(); 
    operatCible.add(4.1); 
    operatCible.add(5.0); 
    System.out.println(operatCible); 

    Table<String, String, Double> employeeYearsOfService = 
    HashBasedTable.create(); 

    employeeYearsOfService.put("AT&T", "Stacy Lerner", 1.4); 
    employeeYearsOfService.put("Microsoft", "Stacy Lerner", 3.5); 
    employeeYearsOfService.put("Microsoft", "Bill Smith", 13.2); 
    employeeYearsOfService.put("Google", "Stacy Lerner", 11.5); 

    employeeYearsOfService.put("AT&T", "Bill Smith", 2.0); 
    employeeYearsOfService.put("Google", "Bill Smith", 9.75); 
    System.out.println(employeeYearsOfService.rowKeySet()); 
    HashMap<String,Integer> result=new HashMap<String,Integer>; 
    System.out.println(employeeYearsOfService); 
    Map<String, Double> attEmployees = employeeYearsOfService.row("AT&T"); 
    for (Map.Entry<String, Double> employee : attEmployees.entrySet()) { 
     // what i do?? 
     // sum values arraylist and values table 
     System.out.println("Employee Name: " + employee.getKey() + ", Years 
    of Service: " + employee.getValue()); 
    } 
    } 
} 

Answer 1

Je résolu mon problème Et j'ajouter quelque chose d'autre (sqrt) .... ce est le code

int k = 0; 
    Double sum = 0.0;//cosine similarity 
    Double sum2 = 0.0; 
    System.out.println(employeeYearsOfService); 
    for (String key : employeeYearsOfService.rowKeySet()) { 
     HashMap<String, Double> hm = new HashMap<String, Double>(); 
     for (Entry<String, Double> employee : 
     employeeYearsOfService.row(key).entrySet()) { 
      sum += employee.getValue() * operatCible.get(k); 
      sum2+=employee.getValue(); 
      k++; 
     } 
     k = 0; 

     System.out.println(sum); 
     System.out.println("----"); 
     System.out.println(sqrt(sum2)); 
     hm.put(key, sum); 
     sum = 0.0; 

     System.out.println(hm); 
    } 


} 

Answer 2

vous pouvez dou que

  HashMap<String, Double> hm = new HashMap<String, Double>(); 
     System.out.println(employeeYearsOfService); 
     for (String key : employeeYearsOfService.rowKeySet()) { 

     for (Entry<String, Double> employee : 
     employeeYearsOfService.row(key).entrySet()) { 
      sum += employee.getValue() + operatCible.get(k); 

      k++; 
     } 
     k = 0; 

     System.out.println(sum); 


     hm.put(key, sum); 


    }
