    Default Need help outputting sub-list of an ArrayList

    Here are my Two classes and a tester. I need help outputting a sub-list of all the Highly Paid employees.

    public class Pay2
    {
     
    private String name;
    private char gender;
    private double hours;
    private double payRate;
     
     
    /**
    * Constructor for objects of class Pay
    */
    public Pay2(String n, char g, double h, double r)
    {
    // initialise instance variables
    name = n;
    gender = g;
    hours = h;
    payRate = r;
    }
     
    /**
    * An example of a method - replace this comment with your own
    * 
    * @param y a sample parameter for a method
    * @return the sum of x and y 
    */
    public double computeGrossPay ()
    {
    return hours * payRate;
    }
     
    public char getGender ()
    {
    return gender;
    }
     
    public double getRate ()
    {
    return payRate;
    }
     
     
    }

    double a = sc.nextDouble ();
    double w = s.computeSalary();
    double m = s.computeMale();
    double f = s.computeFemale();
    int h = s.highPay(a);
     
    System.out.println("The weekly salarys for all employees is $" + w);
    System.out.println("The weekly salarys for all males is $" + m );
    System.out.println("The weekly salarys for all females is $" + f);
     
     
    }
    }

    Any feedback will help.

    Thanks, Allusive
