Boolean vlaue for a video store program - please help!!

[fulcanelli]

Hi,

Any idea how I can add a boolean method that will simply say whether a video is available or not. Such as, 'if' the video is available return true, 'else' return false.

I have to admit I'm pretty useless with boolean statements and would appreciate any advice.

The program is a simple Video store management program. My current code is as follows,

package videos;
 
public class Video {
    
    private int days, referenceNumber;
    private static double dailyPrice;
    private double totalPrice;
    private Title videoTitle;
    
    public Video(int refNum, Title t, int d, double dp) {
        referenceNumber = refNum; videoTitle = t; days = d; dailyPrice = dp;
    }
    
    public Video(int title, String film, String lead1, String lead2, String dir){
        videoTitle = new Title(title, film, lead1, lead2, dir);
    }
    
    public Title getTitle() {
        return videoTitle;
    }
    
    public int getReferenceNumber() {
        return referenceNumber;
    }
    
    public void setReferenceNumber(int refNum) {
        referenceNumber = refNum;
    }
    
    public int getDays() {
        return days;
    }
    
    public void setDays(int d) {
        days = d;
    }
    
    public double getDailyPrice() {
        return dailyPrice;
    }
    
    public void setDailyPrice(double dp) {
        dailyPrice = dp;
    }
    
    public double getTotalPrice() {
        return totalPrice;
    }
    
    public void ApplyTotalPrice() {
        totalPrice = days*dailyPrice;
    }
    
    public String toString() {
        return referenceNumber + "" + videoTitle + "" + totalPrice;
    }
}

Also, do you think the above method for calculating TotalPrice will work in this class?

Any help appreciated!!

have a data member to your class which is a boolean - available

this member's value is returned by the method isAvailable().

Any action relating to the check out, check in, etc. of the video would include a query to isAvailable().

if (isAvailable() )
{
this.checkOut()
}
else
{
System.out.println( "Sorry, this title is not available. Choose another." );
}

or something like that ....
