Adding amount of salary of 5 arrays of player objects inside 5 arrays of team objects?

Main:

System.out.print("Enter player's salary: ");

double salary = input.nextDouble(); // user enters player's salary (user is creating each individual player object here into array slots)

Team[] teams = new Team[5];

Team class:

private double sum; //the total sum of 5 player's salary under a team

Player[] players = new Player[5];

Player class:

private double salary; //salary of an individual

Player(String fN, String lN, int h, int w, int a, double sal){ first_name = fN; last_name = lN; height = h; weight = w; age = a; salary = sal; } //constructor

Player public void setSalary(double sal) {

salary = sal;

}

and

public double getSalary() {

return salary;

}

How would I create the method to add the sum of each Player's salary from the Player's class into the variable "sum" in the Team class? (like using a for loop in a mutator or something?)

A note that the Player array is created in the Team file and Team array is created in the main file. (somewhere in the lines of teams[i].players[i].getSalary or sum += players[i].getSalary();)
