Thanks in Advance....

public class ThreadStarter extends Thread
{
private int x= 2;
public static void main(String args[]) throws Exception
{
new ThreadStarter().makeItSo();
}
public void ThreadStarter(){
x=5;
start();
}
public void makeItSo() throws Exception {
join();
x=x- 1;
System.out.println("answer:"+x);
}
public void run() {
x*=2;
}
}

As I hinted, ThreadStarter() is a method and not a constructor. Hence the default constructor which leaves x untouched is invoked. And later makeItSo() you are decrementing it and hence the output 1.

Constructors in Java should not have any return type (not even void). The moment a return type is specified, it turns into a normal method and hence not invoked during instantiation.

I am Reading Java Series on "Core Java" by Sun MicroSystems Press. It is written by Cay S.Horstmann & Gary Cornell. Although the book is really Good and explains each aspect of java API & associated libraries.

But wonder why they are so much against C/C++:|

anyways, the Book is good read for *programmers* looking to switch to Java. as anyone learning to code first time should skip this. don't believe me check out the first HelloWorld programs given in chapter 1:p

Because those are the languages whose shortcomings, Java was meant to solve. Today C/C++ and Java rule entirely different territories.

I have never read that book. Can you post the code for us to view?

Code: 
public Welcome {
public static void main(String args[]) {

String[] greeting = new String[3]; 
greeting[0] = "Welcome to Core Java";
greeting[1] = "by Cay Horstmann";
greeting[3] = "and Gary Cornell";

for(int i = 0; i < greeting.length; i++)
System.out.println(greeting[i]);
}

}

this is a first program given in the book. the authors call Welcome program extremely simple.

Indeed its simple for programmers but for newbies its a steep learning curve, they have use concepts of arrays,loops etc right into the first program;)

Please check whether you typed in properly. I really don't think it would be this crappy. :confused:

Note: You missed "class" in the first line.

Ha ha ha. ROFLMAO. Thank God they did not introduce design patterns too in the same program. That's why I so love Head First series.
