Can anyone explain me these lines from Carl's Notes:
GridLayout with container larger han components expands to fill its container provided that the number of components matches the rows*columns.
--Empty rows are given space, while empty cols are not.
-- if there aren't enough components, it will try to fill its rows first.

Can anyone explain me whats getCanonicalPath() and getAbsolutePath().
i read that getAbsolutePath() returns the absolute path including the parent directories and as well including the file name itself from where u onvoke this method.
for eg: C:\java\javastudy\file1.txt
is this correct?

how does getAbsolutePath() work?
please explain......

public class Q21
{
int maxelements;
void Q21()
{
maxelements = 100;
System.out.println(maxelements);
}

Q21(int i)
{
maxelements = i;
System.out.println(maxelements);
}
public static void main(String[] args)
{
Q21 a = new Q21();
Q21 b = new Q21(999);
}
}
answer says compilation error at
Q21 a = new Q21()
how explain?

what will happen if you compile/run this code?
public class Q10
{
public static void main(String[] args)
{
int i = 10;
int j = 10;
boolean b = false;
if(b = i ==j)
System.out.println("true");
else
System.out.println("false");
}
}
Answer says True... Please explain!
