Hi,

Yeah i got that, 3tier/n tier is not for integration of server side and client side things, this is just to reduce the load on server ..right??? then what is the difference between MVC -1 and MVC-2 ???
as both (MVC -1 and MVC-2) are used for the same purpose... is MVC-2 related to 3 tier/ n tier??


Please reply

Hi,

As you mentioned in the above answer that in MVC we can modify the server side methods without affecting client side code. that means we Cant do this in 3 tier...???

other this is you said we can use MVC irrespective of tier? i was under impression that in 3-tier also we can use irrespective of tier..??

Please explain..

hi,

I have a program which is printing 22, but i am not getting how?
i think it is calling Extension object so it should print 16...

code
--------------------------------------------------------

class Base {
int i;
Base() { add(1); }
void add(int v) { i += v; }
void print() { System.out.println(i); }
}
class Extension extends Base {
Extension() { add(2); }
void add(int v) { i += v*2; }
}
public class Qd073 {
public static void main(String[] args) {
bogo(new Extension());
}
static void bogo(Base b) {
b.add(8);
b.print();
}
}
-----------------------------------------------------------

please explain how this program will work

Sheetal

ok now i got that..

using y1.equals("Spencer") we are checking the contents of y1, so it is giving true. right?


Thanx again
Sheetal

ok so we are creating the reference & object also using the 'new' operator. & in "Spencer" it is creating only reference, not an object, so not getting the heap memory. if we want to check the object whether it is equal to any value like "Spencer" then will have to check that using .equals or .equalsIgnoreCase. right?


please correct me if am going wrong.

Thanx for the Help
Sheetal

ok .. then suppose this example


public class ExampleTwo {

public static void main(String [] args) {

String y1 = new String("Spencer");

if (y1 != "Spencer") {
System.out.println("You will be picked up early on Tuesday");
}
else {
System.out.println("You will need to stay all day Tuesday");
}
}
}

then why this condition (y1 != "Spencer") is true?

Please Explain

Hi,
I am having problem with the following code.. why the value of y1 is not "Spencer" , why this condition (y1 == "Spencer") is false?


code
-----------------------------------------------------------

public class ExampleTwo {
public static void main(String [] args) {
String y1 = new String("Spencer");
String y2 = "Spencer";

System.out.println("y1 :: "+y1);
System.out.println("y2 :: "+y2);

if (y1 != "Spencer")) {
System.out.println("You will be picked up early on Tuesday");
}
else {
System.out.println("You will need to stay all day Tuesday");
}
}
}
-----------------------------------------------------------

Hi,

I am preparing for SCJP, studying about the modifiers, my qn is why we cannot use 'this' in static method.?


please explain
Sheetal

Hi,

This program is is not giving any problem at compile time, bt at run time nullPointerException is coming,
public class Example5 { public static void main(String args[]) { String str [][][][] =new String[5][5][][]; for(int i=0;i<3;i++) for(int j=0;j<3;j++) for(int k=0;k<3;k++) for(int l=0;l<3;l++) { System.out.println("out"); str[i][j][k][l]=" "+i+j; System.out.println("out1"); } for(int i=0;i<3;i++) for(int j=0;j<3;j++) for(int k=0;k<3;k++) for(int l=0;l<3;l++) System.out.println(str[i][j][k][l]); } }
please explain

ok, the value which is changed here is the value of year only, right? then after that in the method we are assigning the d2 to d1, so it should effect d1 also, bt we are getting 1999 only instead of 2000 in d1.

Why so?

i think am getting confused here, please explain me,
