I would then create a method to compare with each type (by gender, by year, and by last name). In order to compare objects more effectively, I would send these comparing objects Person objects:

	public int compareGender(Person p)
	{
		String tempGen = p.gender;
		return gender.compareTo(tempGen);
	}
 
	public int compareYear(Person p)
	{
		String tempDate = p.date;
		String[] tDateSplit = tempDate.split("/");
		int tempYear = Integer.parseInt(tDateSplit[2]);
		String[] dateSplit = date.split("/");
		int year = Integer.parseInt(dateSplit[2]);
		return year-tempYear;
	}
 
	public int compareLastName(Person p)
	{
		String tempLN = p.lastName;
		return lastName.compareTo(tempLN);
	}

See if you can figure out how to implement this to compare the objects and resort the arraylist.

I hope this helps. It is quite simple to figure this sort of thing out. You just have to work through the problem one step at a time and try to tackle each issue individually.

Well, if there were no limitations, I would create an object (Person Object perhaps). This object would take a First Name, a Last Name, a Gender, a Date, and an Eye Color:

public class Person
{
	String firstName,lastName,gender,date,eyeColor;	
 
	public Person(String fName,String lName,String gen,String dat,String eColor)
	{
		firstName = fName;
		lastName = lName;
		gender = gen;
		date = dat;
		eyeColor = eColor;
	}
}

hi All,

could you please help me with this :

my ArrayList contains objects with person information :

Abercrombie Neil Male 2/13/1943 Tan,
Bishop Timothy Male 4/23/1967 Yellow,
Bonk Radek Male 6/3/1975 Green,
Bouillon Francis Male 6/3/1975 Blue,


I need to get it sorted 3 different ways and print on console 3 sorted sets :

1. by gender
2. by year desc
3. by last name desc

do I need to create Comparators, or ..?

Thank you !
