hi micheal,

could u please mention clearly what is your doubt regarding the code?

In some code i saw,

import DevelopersToolkit.*;
import DragandDrop.*;
import Item.*;
import pipeline.*;

what are all these classes and they are imported from?

we find "java.exe" in both bin and jre/bin folders .
what is the difference between both? are they same?

what is difference between HashTable and HashMap ???

thanks...

please explain the same in detail

what is "out" in system.out.println???

hi anupam,

yes..i got you...if subclass don't extend from superclass,then super()will not be inserted automatically...

Ali pope.....i mentioned ....IF parentclass is assumed as an interface and if test22 implements it ,then call to super class constructor would not be automatically inserted......bcoz interface donot have constuctors......

i request anupam sinha to respond to this answer......

code
____________________________________________________________________________

class ParentClass
{
public ParentClass(String a) // no no-arg constructor
{}
}

public class test22 extends ParentClass
{
String str;
public test22(String a)
{ this.str = a; }
public static void main(String args[])
{
test22 t = new test22("String");
}
}
___________________________________________________________________________

suppose if the parentclass is an interface,then call to super() would not be automatically inserted.....
is it correct scenario, anupam sinha???

if we explicitly call the super class constructor in the subclass constructor...then there will not be any error...

is that correct Anupam Sinha???

--------------------------------------------------------------------------
class ParentClass
{
public ParentClass(String a) // no no-arg constructor
{}
}

public class test22 extends ParentClass
{
String str;
public test22(String a)
{
--> super(a);
this.str = a;
}

public static void main(String args[])
{
test22 t = new test22 ("String");
}
}
---------------------------------------------------------------------------

suppose a java class don't have a constructor...will compiler creates a default constuctor for that class???
