Answer:

class Fields
{
void printFields
(Class c)
{
Field f []=c.getFields ();
System.out.println
("NUMBER OF FIELDS : "+f.length);
for (int i=0;
i<f.length; i++)
{
String fname=f [i].getName ();
Class s=f [i].getType ();
String ftype=s.getName ();
System.out.println
(ftype+" "+fname);
}
}
};
class FieldsDemo
{
public static void main (String [] args)
{
if (args.length==0)
{
System.out.println
("PLEASE PASS THE CLASS NAME..!");
}
else
{
try
{
Class c=Class.forName (args
[0]);
Fields fs=new Fields ();
fs.printFields
(c);
}
catch (ClassNotFoundException cnfe)
{
System.out.println
(args [0]+"NOT FOUND...");
