Strings are immutable right ( mentioned in the text ) apart from theory i want to know the practical application of that.......Like we often change the data of the string many times by using library functions like .toUpperCase or etc.....we use s=s.toLowerCase(); and we get the right output but why not it happens if we write directly s.toLowerCase instead of creating a seperate String object ?? i mean can anyone explain the diff and say how Strings are immutable...practical application is equally important right..so plz

Guys when this is checked in blue j the answer was 176 but i'm not understanding how that would be possible.....i may be wrong in some aspect......plz anyone explain it and say when and where to take care of brackets...........
Guys how exactly string buffer is used in the program part ?? Can anyone give me a precise application explanation as to where and how that has to be implemented...Textbook says that string buffer is better and efficient than strings but i find it confusing and i need to study a lot from text before i could move onto the program part............#PlzsavemeLOL

Identify the invalid integer ...( answer is below ....dont see it till you give it a first attempt.......i too got it wrong on my 1st attempt though )
.Answer is 4 : 01942 ( in octal value/code 0-7 characters would only be allowed ...but here we have 9 in between which is invalid )
many might think the ans is 2 : 0XFACE but the integer value of that is 64,206 ( its an hexadecimal code .......when converted into decimal gives the above value.....if the value is starting with 0X then it is hexadecimal code )
ans 2 is not coz you know why......it is a valid octa decimal code which consists of numbers only from 0-7..........
#HIT Like if you did like it
For a better understanding of keyword ' this ' just refer the textbook example of bank and ATM card and if you'd like to then refer this too..
you'd understand where and why exactly it is used .......Thankyou !
To all the ones who need an application explanation about call by value and call by reference just refer the page 136 of sumita arora text and see the 5.3 program which clearly differentiates between both ( by value and by reference ) .........just see that ...you would get a clear idea and conceptualising would be quite easy ( am not talking about the theory definitions.....) ............

Hey Does anyone know the "standard method" for word extraction accepted in the boards....I do the word extraction process in my own style but in my pre-boards I did this and my teacher cut my marks saying that the board has no time to check such complex codes..so can anyone give me the easier word extraction process??? I can't understand what the council wants from us...they need children who can only cram not understand anything..My problem is the proof that ICSE is encouraging only cramming and nothing else....this board should really change for thebetter of everyone..
