what is the difference between the instance of a class and the class object
produced by [classname].class.

Thanks

I can also invoke function of the loaded class using the class reference. Am I right ? If I am how that happenes.

Class c = Class.forName("className");
Method m = c.getDeclaredMethod
and then invoke the method

How this works ?

Thanks

One loads the class definition into the JVM, the other creates an instance of the class.

Thanks for the reply.

Can you please elaborate " class definition "? Does the Class.forName creates an object of the class in the memory ? If it not, how we run the function of the loaded class.

Can anyone elaborate on difference between Class.forName and new Object call?

Congrats buddy

can you please tell me what is the best book to refer.

Thanks

I have passed SCJP 5.0 Successfully. Thanks to all of you guys and this forum for helping me lot. Best of luck to all of you.

Great Congrats

Congrats really a great score .

Thanks Anuradha,

Really a good description.

Suppose you have a List of 100 elements. Do you want to retrieve all 100 elements using index method...

that is not true right. So iterator will give you fast retrieving of data from List

implement the interface
i.e
interface q {

}

public class nn implements q{
public static void main(String[] arg) {

q o = new nn();
}
}

In the following code the output could be
1 --- 0,2,4,6,8,10,12,14,
2 --- 0,2,4,6,0,2,4,6,
3 --- 0,0,2,2,4,6,4,6,
4 --- 0,0,2,2,4,4,6,6,
5 --- 0,0,2,4,6,2,4,6,

and many more it could be.

public class Thread1 {
int x = 0;

public class Running implements Runnable {

public void run() {
int count = 0;
for (int i = 0; i < 4; i++) {
count = x;
System.err.print(count + ",");
x = count + 2;
}
}

}

public static void main(String[] a) {
new Thread1().go();
}


private void go() {
Runnable r11 = new Running();
new Thread(r11).start();
new Thread(r11).start();
}
}

This is what Thread is ...
bcoz two threads are created and they are accessing the run method at same time.
Thanks. If any mistake pls Rectify.
