Hi ppl,

we know that scriptlets and expressions go inside a _jspservice(), and declarations go outside of _jspservice() when a jsp is converted a servlet.

But in one sample programs which i typed and executed, it is showing all the three scriptlets, expressions and declarations all going inside _jspservice().

so can anybody explain which is true either declaration goes inside or not.

i am totally confused.

THanks,
good guy

Hi,

You are making little mistake in typing a url.it should look like the following

http://localhost:8080/application name/abc.jsp

remember to keep the .jsp file in application folder, that is the folder which contains your web-inf file.

you need to include any information of jsp in a web.xml file.

if any doubt revert back to me.

Thanks,

Hello ppl,

I know that Strings are fixed length, immutable right.

consider the following example and explain how it achieves it.

there is string called

String s = "hello"; ok

when u apply toUpperCase() to the above string it gets changed to "HELLO".

THEN how are you saying it is not mutable. explain please.

Thanks,

Hi friends,

I have one doubt.

Can one object access other objects private variables.If so can
anybody explain.

i know that each object has its own private variables but how can other object access private variables of other object.

Remember both objects belong to same class.

Thanks,
Good guy

hi sirish,

Basically locking an object comes during synchronization areas.

synchronization means only one can access anything.

For example, say myself and u have the same debit card ie having same number on credit card ( we have two copies of credit card with same number).

Suppose i insert card into ATM, at that particular point of time, u are not allowed to access the database (i,e you cant touch data unless one card has finished its transcation) means when one transaction is accessing data, ( indirectly object is locked), u cant allow other transaction to access data.

Have a nice day.

Hi priya,

the program what u have given is working fine except it says deprecated problems. since you are using readLine method which is a deprecated one
i dont find any other problems.

one important thing priya, i the program i dont see where you are checking the number entered, i know you are using assert to check if somebody enters negative number. but where is the assertion statement in program. plz do check once again and revert back to me. ok .

Have a nice day,
Good Guy

Hi sunetra,

I totally disagree with raj.

Remember everything in java is pass by value.

1. For primitives like int, short, double it is pass by value.

eg: int a=5;
somemethod(a); // here you are passing a copy of a's value to somemethod.

2. Even for object references, it pass by value.
eg: A a = new A(); // object a is created.
somemethod(a); // here you are passing a copy of referece to somemethod.

Raj plz understand java is only pass by value, and there is no point of pass by reference.

Thanks,
Good guy.
