大家好，我最近正在从事这项工作，但是我一直在努力寻找一种方法来调用此方法，以便在我获得书名并将其显示在列表上之后
因此调用该方法的类是：
class BookInfo
{
private String strBookTitle;
private char chBookType;
private boolean boolBookFormatAvail[] = new boolean[3];
private double doubBookPrice[] = new double[3];
private String strBookCover;
private String strBookComment;
//set and get
public void setBook( String l)
{
strBookTitle = l;
}
public void setchBookType( char l)
{
chBookType = l;
}
public void setboolBookFormatAvail( boolean[] l)
{
boolBookFormatAvail = l;
}
public void setbooldoubBookPrice( double [] l)
{
doubBookPrice = l;
}
public void setstrBookCover( String l)
{
strBookCover = l;
}
public void setstrBookComment( String l)
{
strBookComment = l;
}
public String getBook ()
{
return strBookTitle;
}
public char getBookType ()
{
return chBookType;
}
public boolean [] getAvailability ()
{
return boolBookFormatAvail;
}
public double [] getdoubBookPrice ()
{
return doubBookPrice;
}
public String getstrBookCover ()
{
return strBookCover;
}
public String getComment ()
{
return strBookComment;
}
BookInfo(String title, char cType, boolean boolFormatE, boolean boolFormatM, boolean boolFormatH, double doubEPrice, double doubMPrice, double doubHPrice, String cover,String strBookCmt)
{
strBookTitle = title;
chBookType = cType;
boolBookFormatAvail[0] = boolFormatE;
boolBookFormatAvail[1] = boolFormatM;
boolBookFormatAvail[2] = boolFormatH;
doubBookPrice[0] = doubEPrice;
doubBookPrice[1] = doubMPrice;
doubBookPrice[2] = doubHPrice;
strBookCover = cover;
strBookComment = strBookCmt;
}

}
public static void main(String[] args)
{
BookList x = new BookList();
System.out.println(x.createList().toString());
}
}
这个方法我想在这里显示：
public void actionPerformed(ActionEvent e)
{
Object source = e.getSource();
String cmd = e.getActionCommand();
BookInfo caca;
BookList pedro = new BookList();
JFrame frame = new JFrame();
if(source == bookType )
{
int b = bookType.getSelectedIndex();
if (b == 0)
{
JOptionPane.showMessageDialog(frame,"No Genre selected");
}else if(b == 1)
{
// here is where the code is supoose to go
}
}
}
我已经尝试过callind类BookList（）的对象，但是不起作用，而且我也尝试使用mu get和set方法只是为了检索也不起作用的信息bu
