Homework - Recompile with -Xlint:deprecation for details

Full error: Example4.java uses or overrides a deprecated API. Recompile with -Xlint:deprecation for details.

I'm not sure why I'm getting this and I still have to do the rest of my printouts but wanted to figure this out first. I've also heard these are just warnings and don't worry about them but I'm not able to test my code to make sure everything is in working order.

import java.util.Date;

public class Example4 {
public static void main(String[] args) {

Buck buck1 = new Buck();


System.out.printf("Buck 1 %s years old");


Buck buck2 = new Buck("10/14/2001", 200.0, 68.0, 6, 2);


}
}

class Buck {


private Date bdate;
private double weight;
private double height;
private int points;
private int horns;


Buck() {
this.bdate = new Date("11/02/2000");
this.weight = 205.5;
this.height = 63.0;
this.points = 10;
this.horns = 2;
}

Buck(String bdateIn, double weightIn, double heightIn, int pointsIn, int hornsIn) {
this.bdate = new Date();
this.weight = weightIn;
this.height = heightIn;
this.points = pointsIn;
this.horns = hornsIn;
}

public Date getBdate() {
return bdate;
}
public double getWeight() {
return weight;
}
public double getHeight() {
return height;
}
public int getPoints() {
return points;
}
public int getHorns() {
return horns;
}


public int getAge() {
Date now = new Date();
int nowMonth = now.getMonth();
int nowYear = now.getYear();
int bdateMonth = bdate.getDate();
int bdateYear = bdate.getYear();

return (nowMonth >= bdateMonth ? nowYear - bdateYear:nowYear - bdateYear - 1);
}

double getmetricWeight(){
return weight / 2.2;
}
double getfeet(){
return height / 12;
}
}

The Date class is an older class. Many of it's methods are deprecated.

So I need to fix it with an updated class to fix this I'm assuming?

That's right. The recommended class is Calendar. For printing out, there is DateFormat.

Perfect...Thanks for your help

How would you rewrite the getAge...Ive tried every way I know of and I'm getting errors across the board

You can create an instance of a Calendar with the static method getInstance(). There are several predefined constants in the Calendar class. In particular, there is Calendar.MONTH, Calendar.DAY_OF_MONTH, etc. If you look at the docs for Calendar.java you will see all of them. You can get a particular piece of information with the get method.
