main() method of a class can be invoked in another class.
Whenever Main method is called, a Main thread gets started right?
In this case how many threads get started?

class a
{
static void main(String args[])
{
System.out.println("----a-----");
}
}
public class b
{
public static void main(String args[])
{
System.out.println("----b-----");
a.main(new String[10]);
}
}

if i tried to run assert false:false;
its saying
Exception in thread �main� java.lang.AssertionError: true
at Test.main(Test.java:3)

i thought that in simple assert statement the first expression should be a boolean, but here its seems that it should be true, and if our assumption is false then assertionError occurs.

is am right please someone explain.

dear all

i am preparing for scjp5.0
can anyone tell how the real exam will be?
i go through some mock exams
is that the real exam is also in the same pattern?
i mean whether the questions will come topic vice?
or all the concepts mingled?

i dont know how much i am clear in this question?
but if i know that will be helpful for my preparation?

thank you

with regards
rahul
