query its hard for me

[srikanth mycherla]

Kindly post answers for these ..please for all my questions with question numbers ..
class wo
{
static int sum( int a, int b)
{
return (a+b);
}
}

class wer
{
static int b=4,c=6;
public static void main (String args[])
{
int a;
a=wo.sum(c,b);
System.out.println(a);
}
}
1)In this program when i say int a; does that mean it is a static
datamember as i have declared inside a static main method or is that a
local variable ?

2) if i declare int b=4,c=6 inside main does that mean they are static members ..if they are local members how can a static method ( int sum(int a,int b ) can access local members ?since rule says static method can access only static members..

3) if static method can access static members(rule according to java )
why am i unable to declare static int b=4 , c=6 inside main
and print the sum using this called method
static int sum(int a, int b)
{
return (a+b);
}

4)Is there any situation like this in java


class a
{
public static void main (String args[])
{
void display()
{
System.out.println("asldjflaj");
}
}
I do know that its a compile time error
I do know that we cant write method defintion inside a method..am i right.or is there any different supporting statement for this ?


5) is there any chance in java to make a method or a data member static without preceding with the keyword static ?


if i say static int a()
{
int b;//is this a static member or a local variable or instance member
}

Hi,

You should rather post these questions in the "programmer" forum:

good luck!
