[velan vel]

public class Test2 {



public static void main(String args[]){



Object x = null;

giveMeAString (x);



//First println

System.out.println (x);



me m1 = new me();

m1.f1="Outside method";



testme(m1);

//Last println

System.out.println(m1.f1);



}



public static void giveMeAString(Object y){

y="Iam inside method";

}



public static void testme(me y){

y.f1="modified inside method";

//inside println

System.out.println("Inside "+ y.f1);

}







}



class me{

public String f1=null;

public String f2=null;

}

What happened when you tried it?

velan please Use Code Tags when you post a source code. That way your code looks formatted. Unformatted code is hard to read. You can add code tags by wrapping your code in [code] [/code] tags. You can edit your message using button and then add code tags to it.

Also please remove the unnecessary blank lines in the code and indent it properly...

output:
null ( see red)
Inside modified inside method ( see orange)
modified inside method ( see brown)

the comment themselves tell the sequences of the print statements
