Hello,Everybody:
	I'm new to java.I'm now confused by the sequence of initializing
static members of a class.
	Here is an example which I wrote for testing:

class InitSequenceClassA{
	static int i=0;
	public InitSequenceClassA(){
		i=15;
		}
	public InitSequenceClassA(int i){
		this.i=i;
			}
	static void increment(){
		i++;
		}
	}
class InitSequenceDemo{
	public static void prt(String s){
		System.out.println(s);
		}
	InitSequenceClassA isc = new InitSequenceClassA(10);
	static InitSequenceClassA isc1, isc2;
	static{
		prt("isc.i=" + isc1.i+ "isc2.i=" + isc2.i);
	
		isc1 = new InitSequenceClassA(27);
		prt("isc1.i=" + isc1.i + "isc2.i=" + isc2.i);
	
		isc2 = new InitSequenceClassA(15);

		prt("isc1.i=" + isc1.i + "isc2.i=" +isc2.i);
	}	
	public static void main(String[] args){
		InitSequenceDemo d= new InitSequenceDemo();
		prt("d.i=" + d.isc.i);
		
		prt("isc.i=" + isc1.i+ " isc2.i=" + isc2.i);
		isc1.increment();
	
		prt("isc.i=" + isc1.i+ " isc2.i=" + isc2.i);
		prt("d.i=" + d.isc.i);
		}
	}


Compile and excute this class we will get output as follow:

isc.i=0isc2.i=0
isc1.i=27isc2.i=27
isc1.i=15isc2.i=15
d.i=10
isc.i=10 isc2.i=10
isc.i=11 isc2.i=11
d.i=11

The first three lines of the output,that is
isc.i=0isc2.i=0
isc1.i=27isc2.i=27
isc1.i=15isc2.i=15

What happend to create the first three lines?
I think it might be:
1.the loading of class InitSequenceDemo;
2.after the loading of method main,the creating of object d;
which is right?

And which of the above actions comes first?
I mean loading of a class where main method located and loading of
method main,which comes first?

Any help will greatly be appreciated!
Thanks in advance!
