Reflection

I hav written a simple code for finding out all the data fields of a class but i am getting an exceptio :"NoClassFoundException".....I am not understanding hoe to remove it...I would glad to receive any one's help....

import java.lang.reflect.*;


class SampleField
{ public static void getField(Class c)
{ //Class c= Class.forName(s);
Field f[]=c.getFields();
for(int i=0;i<f.length;i++)
{ System.out.println(" ");
Class type=f[i].getType();
System.out.print(type.getName());
System.out.print(""+f[i].getName());
}
}

public static void main(String... s1)
{ try{
Class c= Class.forName(s1[0]);
getField(c);
}catch(Exception e){System.out.println(e);}
}
}

Add the class that was not found to the classpath when you run the program.

You removed the important part :)
s1[0] = ???
Which String do you pass to your programm? Is the ending .class? Remove it. Is the class in a package? Then write package+classname.

import java.lang.reflect.*;
import java.awt.*;


class SampleField
{ public static void getField(Class c)
{ //Class c= Class.forName(s);
Field f[]=c.getFields();
for(int i=0;i<f.length;i++)
{ System.out.println(" ");
Class type=f[i].getType();
System.out.print(type.getName());
System.out.print(""+f[i].getName());
}
}

public static void main(String... s1)
{ try{
Class c= Class.forName(s1[0]);
getField(c);
}catch(Exception e){System.out.println(e);}
}
}



I am sending a class name java.lang.thread through command line argument but still it is showing the same exception....:(

Did you use the right case, Thread instead of thread?
